How Outdoor Enthusiasts Can Help Scientific Research About Climate and Wildlife

The nonprofit Adventure Scientists unites skilled outdoors people with scientists to help drive critical conservation work.

When Gregg Treinish set out to hike the length of the Andes Mountains at age 24, there was a lot he didn’t know. For starters, he didn’t realize he and his hiking partner, Deia Schlosberg, would be the first to do it. Or that their 22-month, 7,800-mile trek would gain them international recognition.

He also had no idea what he would do next — but he sure had a lot of time to think about it.

Treinish eventually decided to combine his love of outdoor adventuring with his desire to make a positive impact on the world. The result is the nonprofit Adventure Scientists, which he founded in 2011.

The organization enlists the skills of adventurers, who often travel to remote or hard-to-reach places, to gather data for scientific studies focused on solving environmental challenges. In the past decade Adventure Scientists has helped collect information on pikas, pine martens, plastics and more.

The Revelator spoke to Treinish about combining passion and impact, why this work can be a catalyst for big life changes, and what exciting projects are coming up for him next.

How did you start adventuring?

I grew up in Cleveland in the suburbs and didn’t spend a lot of time hiking or backpacking. My parents aren’t outdoors people. But when I was 16, I went on a backpacking trip in British Columbia and just fell in love with the mountains and with traveling in that way. Then I went to college in Colorado and started being in the outdoors a lot more.

I decided to hike the Appalachian Trail in 2004. I really was passionate about being outdoors, but I felt selfish on that trip for not doing anything beneficial. After that I went and worked in wilderness therapy for a while, taking kids out who were struggling. That furthered my experience and skills in the backcountry.

Then [Deia Schlosberg] and I set out on this journey to trek the Andes, not knowing we would be the first to do it. I thought hundreds of people would’ve done it or would be doing it. We just kind of settled on South America after looking around the world at different long trails.

There wasn’t actually a long trail in South America, but it was clear that we could link stuff together. So we did. We were blogging and posting about it as we went. We had a few sponsors, and somewhere along the way people started following along. We got some magazine articles and wrote some articles. Then National Geographic saw us present in a parking lot after we were done and named us Adventurers of the Year. That opened up every opportunity in the world for us.

When did you combine that passion with the idea of having scientific impact?

One of the things that I love most about long-distance trekking adventures is that it’s just endless hours to think. It’s really a mind game to do expeditions like that. For me it was “What’s next?” and “What am I going to do with my life?” The same questions that we all ask ourselves, but while trekking the Andes, I actually had a lot of time to figure that out and think about it.

When I was finished, I really wanted to study animal behavior and learn how to help species survive and thrive. Lions was where I was focused. There’s a guy here in Bozeman named Scott Creel who studies predator-prey interactions in Africa and applies the carnivore-prey relationships that he learns about there to this ecosystem, because there are a lot of corollaries.

I called him up and said, “Hey, I’m in Patagonia, I just finished walking here from Ecuador. Can I come study with you?” And he was like, “Of course.”

[Deia] was also interested in a film program here. So we moved to Bozeman. I got an undergraduate degree in wildlife ecology and then before I ever made it to Africa with him, I got a job tracking lynx, wolverines and grizzly bears here.

This incredible guy named Steve Gammon taught me how to track, taught me what I was looking for. It’s not rocket science to do it, so we started engaging the public. We would hold these weekend retreats and have people come out and learn how to track with us.

Once we had a reported sighting, I would go and find the tracks and collect DNA. I also had other tech jobs where I worked in California with spotted owls. I worked on the Fort Peck Reservoir on the Missouri River studying pallid sturgeon.

It was awesome. I loved being out there, using my outdoor skills and actually helping — feeling like I was making a difference. I believed that there were more people like me who wanted to make a difference if given an easy opportunity to do that. And then there were also a lot of scientists who needed data. So I combined the two.

Every project we do is designed in partnership with a scientist or multiple. It’s them saying, “We need these data to solve this problem or to address this issue.” We couldn’t do this work without incredible scientists who are trying to solve really big issues.

What kind of projects has Adventure Scientists done?

Early on we did white-tailed ptarmigan studies. We did a pika study, which led to a big publication in Nature. Somewhere around 2014 or 2015 we transitioned to doing much less but much deeper work.

Since then we’ve worked on restoring pine martens to the Olympic National Forest with Betsy Howell of the Forest Service. We’ve partnered with Harvard Medical School to collect scat samples from more than 100 countries that were then used to help narrow the search for the genes that are responsible for antibiotic resistance in enterococci bacteria, which have applications for other bacteria. We have collected the largest data set in the world for microplastics with Abby Barrows.

Currently we’re working with the Forest Service to collect chemical and genetic reference libraries across species of trees. Those are being used by the Department of Justice to prosecute timber theft.

It’s been a very wide swath of projects. I’d say the commonality between them is three things: Is there a big environmental issue that is data-limited? Is there a pathway from collecting data to doing something about the issue? And is there a clear need for involvement from the outdoor community?

What motivates the adventures that volunteer?

Every volunteer probably has a little bit different motivation, but I think in general it’s that we are so lucky to get to play in the outdoors. We’re so fortunate to even have the ability, let alone the resources and the time to do it. So how can I give back? There are so many different types of volunteerism, but I think what’s really cool about this is that you’re uniting passion with giving back. I think that really resonates with people.

We’ve had volunteers who have said that this has been the catalyst to get them to wake up to these issues, to dedicate their lives to them, to pursue careers in conservation. People have gone on to get graduate degrees. Others have started their own nonprofits focused on the issue that they’ve worked on.

I think the other big thing is that many of our projects really require a focus on the environment, like looking for a particular species of bird. Once you learn how to look at the environment in that way, that never goes away. The people who I used to take out tracking would say this, and the people who are keying in on specific species of trees say that every time you walk through a forest, from that point on, you have a different set of eyes.

I’m sure somebody has come up with a name for this, but it’s like, you’re walking along and you see this one purple flower you hadn’t noticed before. It’s so beautiful and you look at it, try to ID it, but then you pick your head and realize they’re growing all around you. That’s the kind of thing that happens. [Our volunteers] start to see the forest by actually tuning in with a different lens. That’s a catalyzing experience for them.

What’s next?

As far as specific issues, we’re working on a really exciting survey of Wild and Scenic Rivers with three federal agencies and over 40 state agencies that will benefit from the data. That project I hope will continue long into the future. We also have work coming up with forests, climate change and biodiversity.

We are also going to be expanding internationally. We were very international initially, but as we focused on more in-depth work a lot of our projects became North America-focused. But we have a lot of experience and knowledge to gain working internationally, and that’s going to be a big focus for us in our next round of growth as an organization.

I’m really excited about that for two reasons.

One is that the promise of this organization has always been international, and I’ve built it believing that we will always be global. And I’d like to make that true.

The second is that the issues we’re working on are international. Illegal forestry, for example. I think 1% of illegal forestry happens in the United States and the rest happens all around the world. And that’s true with climate change issues. In the Global South, people are disproportionately affected by these issues.

We want to be where we’re needed most. We want to be where we can have the most impact.

A Nose for Science: Conservation Dogs May Help in Search for Endangered Franklin’s Bumblebee

Helping Wildlife Survive Climate Change

The new book Nowhere Left to Go shows how climate change threatens myriad species. But there are ways we can help.

This is an adapted excerpt from Nowhere Left to Go: How Climate Change Is Driving Species to the Ends of the Earth © 2021 by Heyne Verlag a division of Penguin Random House Verlagsgruppe GmbH, München, Germany. English-language translation copyright © 2022 by The Experiment, LLC. Reprinted with permission of The Experiment. Available wherever books are sold.

The EU Commission’s vision for making more room for nature includes those areas outside the reserves, known in technical jargon as “the matrix.” Agricultural land and cities cannot easily be dismantled to clear the way for species on the move. Often, however, all they need are stepping-stones.

Cities should therefore, in Brussels’s view, be furnished with woods, parks, and gardens; city farms; green living roofs and walls; promenades, hedges, and meadows, where “excessive mowing is to be avoided.” At the same time, a minimum of 10 percent of agricultural land is to be reserved for buffer strips, for fallow land and hedges, trees, and ponds. Ideally, this would enable species to hop from one refuge to the next.

Conservationists in the western US have developed a flexible solution. They want to turn the Californian longitudinal valley back into a preferred stopover for migrating birds making the journey from South America to the Arctic. Over a period of many years, one wetland after another was replaced with fields, and numbers of these feathery long-distance fliers dropped drastically. Conservationists used birdwatching maps to determine where and when the birds would gather in the remaining wetlands. They rented fields from rice farmers for the duration of the period when the birds would be stopping. The farmers flooded their fields, turning them into wetlands for several weeks. This approach could be applied to other species embarking on one-way journeys.

At the heart of this concept is the notion of reconciling with nature. To stop species extinction, human beings must transform the landscapes they have long dominated, so that they can be used by as many species at once as possible — be this temporary or permanent.

Proponents of this approach argue that the return of nature to our landscape and settlements might soothe a deep-rooted yearning for proximity to the natural world. Studies show that people who spend more time in nature are healthier and happier. The science community refers to this as “Vitamin G,” where “G” stands for “green space.”

We have grown increasingly estranged from nature in the past fifty years. Children, in particular, are having less and less contact with nature in their everyday lives, instead spending more and more time in front of screens. This has consequences: Children exhibit poorer cognitive and motor skills, experience a higher incidence of mental health problems, and place less value on social cohesion. What’s worse is that the growing generation no longer recognizes how dependent we are on the natural world, and why we need to protect it. In the science community, this is known as “shifting baseline syndrome.” People are steadily lowering their expectations of a healthy environment because they measure the state of nature according to the best experiences they had as children. In other words, they are becoming accustomed to the decline of the natural world.

Conservationists are working to combat this in Great Britain, where they are planning a whole network of pathways of flowering plants to protect pollinators across the country. Those running the initiative hope to cover 370,650 acres with wildflowers. These corridors, each just under two miles wide, are intended to allow wild bees to move back and forth between their isolated habitats as they respond to climate change. “It’s important for animals to be able to move from south to north,” says Catherine Jones, Pollinator Office at the conservation organization Buglife.

Time and again, wild bee conservationists gathered around a table in their office in Peterborough in the east of England to stare at an enormous map of the country. They could see forests, meadows, and heaths, rivers, ponds, and lakes. The activists discussed how best to connect these wild bee habitats to each other and what the most suitable routes for these “insect pathways” might be. They shared suggestions and drew lines. Next, they consulted environmental authorities, the government, city councils, other conservationists, and farmers. “We asked them whether they could transform 10 percent of their land into pollinator-friendly habitats,” says Jones.

In the meantime, they have mapped large areas of Great Britain and provided the first 1,200 acres with potential wild bee pathways. Some of these also run through cities — along stepping-stones like parks and gardens. English lawns are to give way for colorful wildflower meadows, where possible fallen branches will not be cleared away, holes in the ground will no longer be filled in, and metal fences will be replaced with hedges. The measures should encourage bumblebees and other pollinators to use these areas to nest and search for food.

Anyone who allows their garden to grow into a meadow or plants an apple tree or a currant bush can add this to the map on the Buglife website. “Some people find long grass untidy, or worry that it will attract garbage,” says Jones, describing her work in Leeds. “But most people want to get involved.”

There are limits, of course. Not all landscapes shaped by human beings can be redesigned to suit other species. And the debate surrounding the reintroduction of wolves, for example, demonstrates that there is a limit to the pleasure many people take in the advance of the natural world. Looking at it from a different angle, many species avoid humans and would never move into a park, for instance, no matter how attractive its redesign might be.

These species require vast, unmolested swathes of land where they are free to roam. And nature reserves are still best suited to this — ideally as large and as connected as the UN agreement on biodiversity will allow. It does not necessarily mean keeping people out of as many of these areas as possible. Responsible engagement is an option, and it is possible.

Indigenous peoples in the tropics are proof of this. The decline of biodiversity in the areas where they live is less pronounced than elsewhere. Perhaps modern man has forgotten how to engage with nature and needs to be reminded. “We have to see ourselves as part of nature,” says Australian biologist Lesley Hughes. “We cannot exist without nature, even if the West likes to imagine that we can.”

Even if we protect a substantial portion of the Earth, we would not be able to save all the animals and plants. Even intact landscapes have many species that are unable to migrate because they are simply too slow, and climate change is too fast. “We also have to think about the consequences if species are unable to move their ranges fast enough,” says Hughes. “Those that cannot escape or adapt will go extinct.”

Move or Change: How Plants and Animals Are Trying to Survive a Warming World

Polluters: Pick Up the Pace Cleaning Up Your Toxic Waste

The Biden administration’s new “polluter pays” tax offers a welcome boost for Superfund cleanup efforts, but it leaves out one key industry.

For the seventh year in a row, the United States is facing an “above-normal” hurricane season, and the increasing number and intensity of these storms puts millions of Americans at a growing risk of toxic waste washing over their communities from long-neglected Superfund sites.

Fortunately a newly reinstated “polluter pays” tax should improve the situation. Since July 1, thanks to the Infrastructure Investment and Jobs Act signed into law by President Biden last year, chemical-producing and importing companies once again need to pay to help clean up the country’s most hazardous toxic waste sites. The bipartisan infrastructure law reinstated excise taxes on 42 chemicals and derivative products that the industry had previously paid from the Superfund program’s inception in 1980 through 1995. Since the payment mandate expired, funding for the program has dropped precipitously, and many toxic sites have remained untouched as a result.

Now, with global temperatures rising, these funds — and more — are urgently needed. More powerful storms and hurricanes in recent years have wreaked havoc by wiping out homes, destroying essential resources, contaminating drinking water, and knocking out power. Two thousand existing and proposed Superfund sites located within 25 miles of the East and Gulf coasts are particularly vulnerable to hurricanes, flooding, and sea-level rise.

When climate change-driven storms collide with Superfund sites, the consequences can devastate nearby communities. Since 1999 Hurricanes Floyd, Katrina, Irene, Sandy and Harvey have all caused flooding at Superfund sites. While much of the immediate devastation of severe weather recedes with floodwaters, toxic waste too often contaminates water, soil and air long after a storm. In 2017 unprecedented rains and flooding from Hurricane Harvey damaged 13 Superfund sites and released toxic contamination into the San Jacinto River.

The reinstated polluter pays tax will provide the Superfund program with a more solid revenue stream to invest in cleaning up toxic waste. The tax is expected to raise approximately $14.45 billion over the next decade, providing a powerful boost to Superfund cleanups.

However, right now it only covers the chemical industry and does not include the fees previously paid by the petroleum industry. The expiration of both industries’ taxes in the 1990s further shifted the burden from polluting companies to the taxpayers and slowed the rate of cleanups.

Congress now needs to finish the job by reinstating a tax on the petroleum industry as well. Reps. Pallone (D-N.J.) and Blumenauer (D-Ore.) have, in the past, introduced legislation that would accomplish this. It’s past time for Congress to reintroduce and pass this tax, especially with prices at the pump soaring and oil and gas companies making record profits. They can — and should — pay their share to keep our country clean and free from toxic waste.

All people deserve to be safe from hazardous materials. This year became a landmark in our journey to make that happen. But we have another leg to go before we’re finished: By forcing the petroleum industry to do its part to fully fund the Superfund program, we can ensure that the EPA has the resources it needs to quickly and safely clean up the United States’ most toxic sites — before dangerous storms help their waste escape.

‘There’s No Memory of the Joy.’ Why 40 Years of Superfund Work Hasn’t Saved Tar Creek

Saving Mother Earth: New Books About Feminism and Women Protecting the Planet

Protecting women’s rights and the environment go hand-in-hand in these new books, which also celebrate female leaders and scientists.

In the wake of the Supreme Court’s devastating decision to strike down Roe v. Wade, it feels more important than ever to talk about the roles feminism plays in environmental protection.

So let’s dig in. Here are publishers’ descriptions of 20 books — most released in the past 18 months, plus a few forthcoming titles and one classic read — that address the intersection of feminism and the environment, explore the female side of nature, or seek to encourage women activists, leaders and naturalists. Many of these volumes will help inspire, while some will shine a light on ignored aspects of nature. And critically, a few of these books are written for the next generation, who now have another of our messes to repair.

Ecofeminism, Intersectionality & Inclusion

The Death of Nature: Women, Ecology and the Scientific Revolution (40th anniversary edition)

by Carolyn Merchant

“An examination of the Scientific Revolution that shows how the mechanistic world view of modern science has sanctioned the exploitation of nature, unrestrained commercial expansion, and a new socioeconomic order that subordinates women.”

The Intersectional Environmentalist: How to Dismantle Systems of Oppression to Protect People + Planet

by Leah Thomas

“From the activist who coined the term comes a primer on intersectional environmentalism for the next generation of activists looking to create meaningful, inclusive and sustainable change. The Intersectional Environmentalist examines the inextricable link between environmentalism, racism and privilege, and promotes awareness of the fundamental truth that we cannot save the planet without uplifting the voices of its people — especially those most often unheard.”

Feminism or Death: How the Women’s Movement Can Save the Planet

by Françoise d’Eaubonne, translated by Ruth Hottell

“Originally published in French in 1974, radical feminist Françoise d’Eaubonne surveyed women’s status around the globe and argued that the stakes of feminist struggles were not about equality but about life and death — for humans and the planet. In this wide-ranging manifesto, d’Eaubonne first proposed a politics of ecofeminism, the idea that the patriarchal system’s claim over women’s bodies and the natural world destroys both, and that feminism and environmentalism must bring about a new ‘mutation’ — an overthrow of not just male power but the system of power itself.”

Fresh Banana Leaves: Healing Indigenous Landscapes through Indigenous Science

by Jessica Hernandez

“An Indigenous environmental scientist breaks down why western conservationism isn’t working — and offers Indigenous models informed by case studies, personal stories and family histories that center the voices of Latin American women and land protectors.”

Ecofeminism, Second Edition: Feminist Intersections with Other Animals and the Earth

edited by Carol J. Adams & Lori Gruen

“Drawing on animal studies, environmental studies, feminist/gender studies and practical ethics, the ecofeminist contributors to this volume stress the need to move beyond binaries and attend to context over universal judgments; spotlight the importance of care as well as justice, emotion as well as reason; and work to undo the logic of domination and its material implications.”

Violent Inheritance: Sexuality, Land and Energy in Making the North American West

by E Cram

“Violent Inheritance deepens the analysis of settler colonialism’s endurance in the North American West and how infrastructures that ground sexual modernity are both reproduced and challenged by publics who have inherited them. E Cram redefines sexual modernity through extractivism, wherein sexuality functions to extract value from life including land, air, minerals and bodies. Analyzing struggles over memory cultures through the region’s land use controversies at the turn of and well into the twentieth century, Cram unpacks the consequences of western settlement and the energy regimes that fueled it.”

Animal Crisis: A New Critical Theory

by Alice Crary & Lori Gruen

“In stark contrast to traditional theories in animal ethics, which abstract from social mechanisms harmful to human beings, Animal Crisis makes the case that there can be no animal liberation without human emancipation. Borrowing from critical theories such as ecofeminism, Crary and Gruen present a critical animal theory for understanding and combating the structural forces that enable the diminishment of so many to the advantage of a few. With seven case studies of complex human-animal relations, they make an urgent plea to dismantle the ‘human supremacism’ that is devastating animal lives and hurtling us toward ecocide.”

Fat Girls Hiking: An Inclusive Guide to Getting Outdoors at Any Size or Ability

Modern Female Leaders & Activists

Still Hopeful: Lessons from a Lifetime of Activism

by Maude Barlow

“In this timely book, Barlow counters the prevailing atmosphere of pessimism that surrounds us and offers lessons of hope that she has learned from a lifetime of activism. She has been a linchpin in three major movements in her life: second-wave feminism, the battle against free trade and globalization, and the global fight for water justice. From each of these she draws her lessons of hope, emphasizing that effective activism is not really about the goal, rather it is about building a movement and finding like-minded people to carry the load with you. Barlow knows firsthand how hard fighting for change can be. But she also knows that change does happen and that hope is the essential ingredient.”

Nature, Culture and the Sacred: A Woman Listens for Leadership (second edition)

by Nina Simons

“Bioneers co-founder Nina Simons offers inspiration for anyone who aspires to grow into their own unique form of leadership with resilience and joy. Informed by her extensive experience with multicultural women’s leadership development, Simons replaces the old patriarchal leadership paradigm with a more feminine-inflected style that illustrates the interconnected nature of the issues we face today.”

Land of Women

by María Sánchez, translated by Curtis Bauer

“María Sánchez is obsessed with what she cannot see. As a field veterinarian following in the footsteps of generations before her, she travels the countryside of Spain bearing witness to a life eroding before her eyes — words, practices and people slipping away because of depopulation, exploitation of natural resources, inadequate environmental policies, and development encroaching on farmland and villages. Sánchez, the first woman in her family to dedicate herself to what has traditionally been a male-dominated profession, rebuffs the bucolic narrative of rural life often written by — and for consumption by — people in cities, describing the multilayered social complexity of people who are proud, resilient and often misunderstood.”

Right Here, Right Now: How Woman Can Lead the Way in the Climate Emergency

by Natalie Isaacs

“The science is clear: if we continue to burn fossil fuels at current rates, the Earth will continue to warm. Already, the consequences of climate change are upon us. Now, in this powerful call to action with optimism at its heart, the founder of the global climate action movement 1 Million Women explains why we all must act, wherever we are, and why, in this decisive decade, we must act now.” (Available Oct. 25)

The Female in Nature

Bitch: On the Female of the Species

by Lucy Cooke

“Since Charles Darwin, evolutionary biologists have been convinced that the males of the animal kingdom are the interesting ones — dominating and promiscuous, while females are dull, passive and devoted. In Bitch, Cooke tells a new story. Whether investigating same-sex female albatross couples that raise chicks, murderous mother meerkats, or the titanic battle of the sexes waged by ducks, Cooke shows us new evolutionary biology, one where females can be as dynamic as any male. This isn’t your grandfather’s evolutionary biology. It’s more inclusive, truer to life and, simply, more fun.”

Sexus Animalis: There Is Nothing Unnatural in Nature

by Emmanuelle Pouydebat

“In the animal kingdom we find heterosexual, lesbian, gay and bisexual behavior, as well as monogamy, polygamy and polyandry … Sexus Animalis tells us everything we never dreamed we wanted to know about the reproductive systems, genital organs and sexual practices of animals.”

Lessons from History

Woman, Watching: Louise de Kiriline Lawrence and the Songbirds of Pimisi Bay

by Merilyn Simonds

“Referred to as a Canadian Rachel Carson, Louise de Kiriline Lawrence lived and worked in an isolated log cabin near North Bay. After her husband was murdered by Bolsheviks, she refused her Swedish privilege and joined the Canadian Red Cross, visiting her northern Ontario patients by dogsled. When Elzire Dionne gave birth to five babies, Louise became nurse to the Dionne Quintuplets. Repulsed by the media circus, she retreated to her wilderness cabin, where she devoted herself to studying the birds that nested in her forest. Author of six books and scores of magazine stories, de Kiriline Lawrence and her ‘loghouse nest’ became a Mecca for international ornithologists.”

A Mighty Force: Dr. Elizabeth Hayes and Her War for Public Health

by Marcia Biederman

“…Elizabeth O. Hayes, MD, doctor for a coal company that owned the town of Force, Penn., where sewage contaminated the drinking waters and ambulances sank into muddy unpaved roads while corrupt managers… When Hayes resigned to protest intolerable living conditions, 350 miners followed her in strike, shaking the foundation of the town and attracting a national media storm. Press — including women reporters, temporarily assigned to national news desks in wartime — flocked to the small mining town to champion Dr. Hayes’ cause. Slim, blonde and 33, ‘Dr. Betty’ became the heroine of an environmental drama that captured the nation’s attention, complete with mustache-twirling villains, surprises, setbacks and a mostly happy ending.”

Windswept: Walking the Paths of Trailblazing Women

by Annabel Abbs

“…a beautifully written meditation on connecting with the outdoors through the simple act of walking. In captivating and elegant prose, Abbs follows in the footsteps of women who boldly reclaimed wild landscapes for themselves, including Georgia O’Keeffe in the empty plains of Texas and New Mexico, Nan Shepherd in the mountains of Scotland, Gwen John following the French River Garonne, Daphne du Maurier along the River Rhône and Simone de Beauvoir — who walked as much as twenty-five miles a day in a dress and espadrilles — through the mountains and forests of France… Abbs explores a forgotten legacy of moving on foot and discovers how it has helped women throughout history to find their voices, to reimagine their lives, and to break free from convention.”

Ten New Environmental Books Offering Inspiration, Insight and Ideas

Salmon Farming’s Dirty Business

A new book looks at the “dark underbelly of our favorite fish” and urges regulators and businesses to better protect wild salmon, coastal ecosystems and consumers.

Sometimes all it takes is a single photograph to change someone’s mind or inspire them to take action. For Catherine Collins and her husband Douglas Frantz, that was a photo of a yardstick plunged 32 inches into filth below a salmon farm near Port Mouton, Nova Scotia.

It led the two investigative journalists to take a deep dive into the salmon-farming industry and its dirty business. The result is their newly published book Salmon Wars: The Dark Underbelly of Our Favorite Fish.

Collins and Frantz, who are also the authors of several other nonfiction books, write about how salmon farming exploded into a $20 billion industry and why that threatens wild salmon, coastal ecosystems and unsuspecting consumers.

There are more than a few descriptions in the book that may leave readers with searing mental images. Here’s one: Sea lice on farmed salmon can number in the hundreds on a single fish, “so numerous that at some fish-processing plants workers use Shop-Vacs to remove them from incoming salmon.”

In an interview with The Revelator, Collins and Frantz explain the threats posed to wildlife, what happens to scientists and activists who challenge the industry, and whether land-based salmon rearing is a better alternative.

Why did you decide to write this book?

Catherine Collins: Salmon Wars may seem like an odd topic for us because neither one of us is an angler, a marine biologist, or even an environmental activist. Instead, we’re like our potential readers — simply people doing our best to eat healthy and responsibly.

That said, we do have connections to the topic that not everyone will have. My father was an avid fly fisherman. For years wild-caught Atlantic salmon was served for special occasions at our house. Sadly, our children have never known that pleasure.

Our view of salmon farms was shaped initially by a small farm that we saw go into the water not far from my parents’ cottage on the South Shore of Nova Scotia in the early 1990s. At first my parents were intrigued. They hoped that aquaculture might take some of the pressure off the dwindling numbers of wild Atlantic salmon. But they realized quickly, as the trash piled up on the shoreline and the eel grass on the seabed below the farm died, that the new technology was not the answer. In fact, it could represent a new threat to wild salmon.

Doug Frantz: Fast forward a couple decades. In January 2020 we went to a public meeting in Mahone Bay, Nova Scotia, a few minutes from our home. A group called the Twin Bays Coalition had sounded an alarm about plans by two multinational salmon-farming companies to locate more than 20 new open-net-pen farms along our coast.

By then salmon farming had grown into a $20 billion industry, and so had evidence of environmental damage from open-net farms. About 400 other people crowded into the community hall and spilled into the corridors that day to hear warnings from environmentalists, lobster fishers, businesspeople and ordinary folks.

We have spent our careers investigating and reporting for newspapers, government and law firms. So we did what we do — we investigated.

We were surprised, and continue to be surprised, by how little people know about the salmon they’re buying in markets or eating in restaurants. Honestly, smart people have no idea about the environmental harm caused by open-net salmon farms or the potential health risks from eating fish that might contain contaminants. This is one of the factors that compelled us to write Salmon Wars.

What are some of the ways that salmon farming can harm wild salmon and other wildlife?

Frantz: Open-net salmon farms are floating feedlots. Each farm generally consists of 10 to 12 cages, also called pens, made of tough plastic netting to allow the ocean currents to flow through while keeping out predators. Each cage holds up to 100,000 fish and a site can contain a million salmon.

The excrement, excess feed and chemical residue from a single farm can equal the waste produced by a town of 65,000 people, according to one study. But a city’s sewage is treated, while a salmon farm simply allows its waste to drift to the seabed, creating a toxic stew that can damage marine life for hundreds of yards.

These farms are often located on wild salmon migration routes. The logic of the salmon farmers is that a good environment for a wild salmon is a good environment for its farmed cousin.

That’s just not true. These farms spew parasites and pathogens that are a proven threat to wild salmon, particularly young salmon as they migrate from rivers to the ocean. One of the biggest threats is from tiny sea lice that attach to those migrating juvenile salmon. It doesn’t take many of these parasites to kill a young salmon.

In addition to the persistent incremental environmental damage, there is a concern about the chance of a catastrophic event — such as the 2017 collapse of the Cooke Aquaculture salmon farms near Cypress Island, Washington. A scathing report by the three Washington state agencies found that the company falsely blamed the collapse on a solar eclipse when it was the company’s own negligence that led to the collapse. In the days after, 250,000 farmed Atlantic salmon escaped into the Puget Sound, competing with the native Pacific salmon for food, threatening native fish with the diseases rampant in the farm environment and potentially interbreeding with the native wild salmon.

Most North Americans likely don’t know that their farmed salmon could have an impact on people as far away as West Africa. Can you explain why?

Collins: Salmon are carnivores and the main ingredient in their feed is small forage fish, such as sardines, anchovies and mackerel. In the early days of aquaculture, it took as much as three pounds of wild fish to grow a pound of farmed salmon. Advances in fish meal production has improved the feed ratio but as salmon farming has grown dramatically around the world, so has demand for wild forage fish.

The impact is clearest along the 3,400-mile Atlantic coast of West Africa, where huge trawlers scoop up thousands of tons of these small fish for processing into fishmeal and fish oil to feed salmon that wind up on dinner tables in wealthier countries.

For Africans, this has been a disaster. The United Nations says half the fish stocks off West Africa are overfished and at risk of collapse. And 40% of these trawlers are operating illegally. Subsistence fishermen have seen catches drop sharply. Women who process and sell the fish in local markets can no longer make a living. And food insecurity is increased in one of the world’s poorest regions.

Do you see similarities with the salmon farming industry and the tobacco or oil industries?

Frantz: We aren’t arguing that eating salmon is as bad for your health as smoking or as bad for the climate as fossil fuels. But there are other parallels.

In the early 1950s tobacco industry scientists discovered links between smoking and cancer. For decades, the industry covered up its findings and waged a war to discredit independent scientists and other critics. The oil and gas industry has tried to shift the blame for the climate crises to individuals, hiding behind slick advertising and captive politicians.

Similarly, big salmon farmers disparage scientists who point out the health and environmental risks from farmed salmon and try to discredit critics. We tell the stories of several people who challenged the salmon farming giants and wound up losing their jobs or facing lawsuits.

Salmon farmers sell their product as naturally raised and sustainable. Last year a federal judge in New York approved a settlement in which Norway’s Mowi ASA, the world’s largest salmon farmer, paid $1.3 million for deceptive advertising, and agreed to stop claiming its Ducktrap brand of smoked salmon was “sustainably sourced,” “all natural” and “from Maine.” This should be seen as a critical moment for the entire industry, and for responsible consumers.

Salmon farming can be reformed, if the public demands that its salmon is raised in healthier, environmentally friendly ways. The fact is that salmon farming, as it has been practiced until recently, is a freeloading business. In most countries salmon farms use the coastline and the water with impunity, paying little to lease the sites and nothing to clean up the damage they cause. In a single-minded pursuit of profit, the multinational corporations behind salmon farming exploit public resources and ignore public health.

Does salmon farming have a future and if so, what would a healthy one look like?

Collins: We think it does. There are three steps necessary to make that happen.

First, consumers need to understand the risks and rewards from eating farmed salmon. That means greater transparency from grocery stores, restaurants and salmon farmers. Something like a QR code on salmon should disclose where and how it was raised and list the chemicals in the water and feed.

Second, individual responsibility should be translated into coordinated action. Educated consumers can team up with environmental groups, scientists and government reformers to build a movement that demands that salmon farmers protect the environment and ensure the health of the fish they sell.

Third, governments in salmon-farming countries should stop favoring the economic interests of the industry over protection of the environment and public health.

The industry justifies itself by saying it plays an essential role in feeding the world. But there are better ways to provide the protein the world needs. One technology with the capacity to upend the status quo is recycled aquaculture systems (RAS). These facilities raise salmon on land in large tanks using filtered and recycled water. They don’t need excessive chemicals or antibiotics because the water quality is controlled. And they don’t threaten wild salmon or other marine life because the fish never touch the ocean.

One issue that even RAS plants haven’t solved is the feed. Using ground fishmeal from small fish means farmed salmon is inherently unsustainable, both in open-net pens on the ocean and giant tanks on land. New types of feed are being developed as alternatives to small fish and governments should support these efforts and consumers should vote with their pocketbooks by demanding the healthier, environmentally friendly salmon grown in RAS facilities.

Here’s the bottom line: Options exist to the open-net salmon farms that dominate our supply chain today. Change depends on the actions both of our governments and regulators, but just as importantly, consumers. Change will come when individual decisions are transformed into public demands, regulatory action and a responsible salmon-farming industry.

We can choose a better way and still feed the world.

Save Salmon, Save Ourselves

WTO Agreement Boosts Efforts for a Sustainable Ocean

Fishing subsidies threaten ocean health and food security. The World Trade Organization has a plan to address that, but implementation must come quickly.

After 20 years of discussion, the World Trade Organization has reached an agreement on fishing subsidies. It states that all members should eliminate harmful subsidies contributing to illegal, unreported and unregulated fishing, and the overfishing of at-risk fish populations. It also requires annual reviews on each nation’s progress on implementation and operations.

This required a difficult consensus of the 164 member states, making the agreement an important step forward. But there are still key loopholes and exceptions that must be ironed out for the agreement to be successful. And any agreement is only as good as its implementation.

According to the UN Food and Agriculture Organization, more than 35% of our world’s fish population has been overfished, and that percentage is only rising. Meanwhile around $22 billion was spent in 2018 on subsidies — public funding to make fisheries more profitable — to increase fishing capacity. In many cases fish populations have been so heavily exploited that fishing vessels rely on the distorting effect of subsidies to turn a profit; one expert analysis puts the figure at over half of current high-seas fishing grounds.

For too long these subsidies have devastated marine wildlife, local livelihoods and food security around the world. Fish are a vital source of protein in least-developed countries. As they are overexploited, vulnerable coastal communities are left at risk of starvation; more than half of the small-scale fishers that my organization, the Environmental Justice Foundation, recently interviewed in Ghana reported going without sufficient food in the past year.

An open letter from the Ghana National Canoe Fishermen’s Council says that if illegal fishing — driven in part by harmful fisheries subsidies — isn’t addressed, “the source of income for over 2.7 million Ghanaians will be lost.”

Small-scale fishers deserve a fair playing field. Once all harmful subsidies are removed, alongside increased transparency and enforcement of regulations to end overfishing, they have a chance to be part of a sustainable global fishing network.

Industrial Trawling

Experts estimate that 81% of governments’ fisheries subsidies benefit large industrial fleets, distorting access to marine resources and destroying the heart of many coastal communities. In Africa twice the amount of subsidies from foreign nations goes toward distant water vessels to fish off the African coast than goes to African vessels themselves.

Shamefully, wealthy countries have been directly funding wasteful overfishing and illegal fishing at the expense of small-scale fishing communities. This WTO agreement means we can give fishing communities a chance of survival and begin the end of this clear injustice.

However, this deal is just the start of the shift we need toward a more sustainable fishery sector. Harmful fisheries subsidies aren’t limited to those that prop up illegal fishing or overcapacity. At the moment prohibitions on fuel subsidies — 22% of all fisheries subsidies — have been left out of the text, meaning that there’s still work to be done to restore a truly thriving ocean.

Blue Carbon and the Climate Crisis

This agreement is good news for the climate, too, as the ocean is the world’s largest carbon sink. Around 43.5% of the carbon in marine life like fish — so-called “blue carbon”— extracted from the high seas comes from areas that would be unprofitable to fish without financial support, so we have been driving ocean ecosystems to collapse and speeding up the climate crisis with the same set of subsidies.

For every degree Celsius of warming, global fisheries catch potential will fall by more than 3 million metric tons. These impacts will predominantly be felt by equatorial countries, many of them low-income, where their annual catches will fall by half. This means that ending some of these subsidies for good protects our climate, ocean and peoples’ food security and livelihoods with one stroke of the pen.

Implementation

It’s clear that this agreement has the potential to bring an opportunity for our over-exploited oceans to recover, but at present it relies too heavily on self-reporting from subsidizing member countries, with no binding enforcement measures or mechanism to ensure countries follow through.

All countries must implement the agreement as well as go beyond it, by urgently reflecting this decision in their domestic regulations and removing all harmful subsidies — not just those covered in the agreement — ensuring transparency throughout the process. The European Union and the United States — which both have strong commitments to fight illegal, unreported and unregulated fishing globally – should move quickly and lead by example in removing harmful subsidies from their fleets. But every nation can and must go faster and further than this agreement for a truly sustainable ocean.

At present, subsidies will be limited for at least the next four years as negotiations to expand the reach of this agreement will continue for the duration. We don’t have four more years to continue at this pace — we need quick, joint action from the international and national levels. While the WTO must speed up negotiations to expand the agreement’s remit and make it binding, national governments must also go beyond what the WTO mandates and use their powers to drive sweeping change in both policy and action.

Two key additional aspects will be ending fuel subsidies and addressing subsidies that support fishing overcapacity, which allows fishers to go beyond sustainable catch levels. The latter is mentioned in the agreement, but no comprehensive deal was made. Both international and national actors must include fuel subsidies and fishing overcapacity in their agreements and policies, as well as take more immediate action toward implementing it.

It has taken two decades for the WTO to take meaningful action on ending subsidies for overfishing. We can’t afford to take this long to implement this agreement. If fishing nations take action now and cut the flow of finance to illegal fishing, overfishing and overcapacity, we can drive real progress toward a secure and sustainable future for the ocean and the people who depend on it.

‘Soil Isn’t Forever’: Why Biodiversity Also Needs Protection Below the Ground

We know more than ever about the abundance of life in the soil. Now we have to step up to save it.

Look down. You may not see the soil beneath your feet as teeming with life, but it is.

Better scientific tools are helping us understand that dirt isn’t just dirt. Life in the soil includes microbes like bacteria and fungi; invertebrates such as earthworms and nematodes; plant roots; and even mammals like gophers and badgers who spend part of their time below ground.

It’s commonly said that a quarter of all the planet’s biodiversity lives in the soil, but that’s likely a vast understatement. Many species that reside there, particularly microorganisms such as viruses, bacteria, fungi and protists, aren’t yet known to science.

“Published literature has only just begun to unravel the complexity of soil biological systems,” a 2020 study by researchers from University of Reading found. “We barely know what is there, let alone their breadth of functional roles, niche partitioning and interaction between these organisms.”

But what scientists do know is that healthy and biodiverse soil communities support a wide variety of functions that sustain life on Earth. That includes nutrient cycling, food production, carbon storage and water filtration.

What happens belowground supports life aboveground. And not surprisingly, if that underground biodiversity is threatened, so are the important functions that soil performs.

“When soil organisms begin to disappear, ecosystems will soon start to underperform, potentially hindering their vital functions for humankind,” wrote researchers in a 2020 Science study.

Threats

Unfortunately there’s evidence that soil biodiversity is decreasing today — how badly is still a matter researchers are working to determine. By just one metric, studies found that 60–70% of soils in the European Union are now unhealthy.

The threats there — and across the world — are numerous.

The Reading University researchers narrowed them down to five main areas:

Human exploitation, including intensive agriculture, pesticides, fertilizers and genetically modified organisms.
Land-use change like deforestation, habitat fragmentation, and soil sealing.
Soil degradation from compaction, erosion, and loss of nutrients.
Climate change, which influences temperature and moisture.
The growing threat from plastic pollution.

“Land changes [like intensive agriculture] are right up there with climate change,” says Diana H. Wall, a biology professor at Colorado State University and director of the School of Global Environmental Sustainability. “Because what we’re doing is tearing up the soil. And that’s the habitat for all these species.”

When we lose biodiversity in the soil it leads to a decrease in the soil’s ability to withstand disturbances — that could cause a loss of important functions and even more biodiversity.

Knowledge Gaps

Much like new molecular tools have helped researchers understand the microbiome in people’s guts, scientists can now also learn much more about the tiny organisms living in the soil, says Wall. But while research about soil biodiversity is growing, there are still significant knowledge gaps.

A 2020 study on “blind spots” in global soil biodiversity and ecosystem function found that most research focused on a single sampling event and didn’t study how soil changed in the same area over time, which the authors say is “essential for assessing trends in key taxa and functions, and their vulnerability to global change.”

The research has also been geographically unbalanced, they found. Temperate areas, which include broadleaved mixed forests and the Mediterranean, have received more study than many tropical areas, tundra or flooded grasslands.

This is not a new problem: Another study revealed that we lack historical information on soil biodiversity that would make it possible to understand baselines on previous land cover and local drivers of biodiversity. Without understanding past conditions, it’s not clear how things are changing or why.

Knowledge gaps aren’t just limited to science, either. When it comes to policy, national and international bodies lack systematic ways to monitor and protect soil biodiversity.

“At the global scale, soil biodiversity is still a blind spot: most Parties of the Convention on Biodiversity neither protect soils nor their biodiversity explicitly,” found a study published in April in Biological Conservation.

Taking Action

Efforts to better study and protect soil biodiversity have begun to ramp up.

One is the Soil Biodiversity Observation Network (Soil BON), co-led by Wall, which is a coordinated global project to monitor soil biodiversity and ecosystem function to help inform policy.

Wall also leads the Global Soil Biodiversity Initiative, a volunteer scientific network of more than 4,000 researchers who are studying the vulnerability of belowground biodiversity. The group recently sent a letter to the United Nations Convention on Biological Diversity urging action to protect soil biodiversity.

“Knowledge of the importance of the vast diversity of fauna and flora that inhabit soil and sustain all life aboveground should be recognized and included in global policies for the protection, restoration, and promotion of biodiversity,” the group wrote.

Europe isn’t waiting for the U.N. to take action.

The Farm to Fork Strategy, part of the European Green New Deal, calls for better soil protection, including cutting pesticide use in half by 2030. The European Union also launched the Zero Pollution Action Plan for Air, Water and Soil that aims to improve soil quality. And the EU could push further action with a planned Soil Health Law in 2023.

And while soil health demands more big government efforts, there are a lot of changes at the local level and by industries that could help.

In urban areas, pavement that has sealed off soil can be removed and replaced by vegetation. The construction of green roofs and gardens rich in plant diversity can aid soil biodiversity, too.

Farmers, Wall says, have also expressed increasing interest in soil regeneration and carbon sequestration. “There are definitely things that you can do to return the organic matter to the soil,” she says. “What we want is good cover for soil so it doesn’t blow away or wash away. And we also want to make sure that we’re not just cutting vegetation down to bare ground.”

Society also needs to be mindful of the chemicals that we use in our homes, farms and cities, she says: “Pollution in soil is very bad for the organisms that live in the soil, and it’s bad for any that may have a pupating cycle in the soil.”

Soil biodiversity can recover after industrial or agricultural sites are taken out of production, but it may happen slowly and require specialized restoration efforts. In those cases, “microbial transplants together with seeding of target plant species might help speed up these processes,” suggests a 2019 study co-authored by Wall. “Even small changes, which often come at little monetary cost, may increase soil biodiversity and ecosystem services.”

And an even smaller change is also important — getting people to notice and appreciate the role healthy soil plays in our lives and why it’s so vital we protect it.

“Something that we really ought to realize is that soil isn’t forever,” Wall says. “Soils are vulnerable, and we know that worldwide. Pay attention to the life beneath your feet — it’s fragile.”

Why It’s Time to Include Fungi in Global Conservation Goals

Armadillos Make Great Neighbors

Despite their reputation as destructive pests, new research reveals that armadillos support dozens of other species — including, possibly, humans.

When people encounter armadillos, they usually describe the armored mammals in derogatory terms.

“Pests” is a common word, as are “invaders” and even “speed bumps.” Many homeowners brag of “eradicating” them from their properties.

Why the hatred? Nine-banded armadillos (Dasypus novemcinctus) — the only armadillo species in the United States — have slowly expanded their range through the southern and midwestern United States over the past few decades, a process that’s sped up in recent years. Whenever they arrive, they start digging — either to find tasty insects or grubs to eat, or to carve out the large burrows they call home. Those holes can disrupt agricultural fields, backyard gardens and golf courses. And all too often, these incursions into human territory cost the cat-sized animals their lives.

“Some of my students are born and raised in Arkansas, and they’ve said that growing up, the prevailing thing to do when you see an armadillo is shoot it,” says Brett DeGregorio, a wildlife biologist and principal investigator at the USGS Fish and Wildlife Cooperative Research Unit at the University of Arkansas.

But people encountering nine-banded armadillos might want to reconsider their attitudes. It turns out their pesky burrows have a lot to offer local communities.

Home Is Where the Burrow Is

DeGregorio, his colleagues and his students study the shifting wildlife of Arkansas. “Fayetteville is a really fast-growing area, so I’m really interested in how the mammal community changes as we develop,” he says.

In their work, they spend a lot of time setting up wildlife cameras in various parts of the state and examining the images they find. Armadillos weren’t the initial targets of their research, but they proved hard to resist.

“The more cameras we put out, the more time we spent in the field, the more and more interested I got in the armadillos. And we started noticing these patterns.”

As patterns revealed new research questions, DeGregorio encouraged his students to point their motion-triggered cameras at armadillo burrows whenever they were in the field. And they found plenty of burrows to study.

“Each armadillo usually digs about ten of them within their little home range,” he says. “So even if you only have a few armadillos living in the area, you have lots of these holes, and they’re only using one at any given time.”

The burrows themselves are amazing structures. “There’s a perfectly round opening,” he says, “and they don’t go too deep into the ground — maybe three feet down — but they’re really long. If you were to stick your arm down one, you probably couldn’t get to the end.” Armadillos, he points out, don’t do very well in cold weather, and burrows help keep them warm in the winter and cool in the summer.

Ultimately, the researchers spent a year collecting images from burrows at 35 sites across Arkansas, including a woodlot in a suburban neighborhood, a heavily forested park in the Ozark Mountains, a national wildlife refuge, and a rural cattle pasture.

Along the way they documented plenty of armadillos — and a lot more.

A Community of Critters

The research, published this May in the journal Ecology and Evolution, found that nine-banded armadillo burrows were incredibly popular sites, used not just by their original architects but also by at least 64 other species. This included bobcats, foxes, opossums, raccoons, skunks, frogs, skinks, snakes, turtles and 40 bird species.

Some of these animals, like groundhogs and foxes, took over armadillo burrows and adapted them for their own use. The researchers documented one red fox giving birth in its new home, and several Virginia opossums spent long periods in burrows caring for their newborns.

Other animals used the burrows to store food. Cameras frequently caught gray squirrels hiding acorns near or on burrow entrances and later digging them up — if mice didn’t steal them first.

Still other species used burrows as hunting sites. Those acorn-seeking mice made great prey for red-tailed hawks, which appeared to stake out burrow entrances.

DeGregorio says he wasn’t surprised by what they found because similar behavior has been documented around the burrow of other species — notably, tortoises.

“Gopher and desert tortoises get a lot of credit for being these ecosystem engineers because they also dig these extensive burrow systems,” he says. “That’s one of the key talking points for conservation of the tortoises: that they benefit so many other species.”

He expected a similarly extensive list of species benefiting from armadillo burrows — and he found it: “They create a lot of refuges for other animals to take advantage of.”

That may provide a whole other layer of benefits.

“If you’ve got armadillos around, the general biodiversity in that area is probably higher,” DeGregorio says. “To turn this into a selfish, human-centric thing: We know that biodiversity is directly linked to many human health benefits. One of the species we saw using these burrows the most was the Virginia opossum, which are amazing tick predators. The more opossum we have around, the fewer ticks and the lower prevalence of Lyme disease and the other nasty stuff that keeps us up at night. If armadillos can contribute to that, especially in suburban and rapidly developing areas where they persist really well, I think we should embrace that.”

Shifting Patterns

But those rapidly developing areas come with costs for armadillos.

In another study stemming from the same research, DeGregorio and his team found that humans don’t always make the best neighbors for these armored animals.

It’s not just their perpetual persecution of armadillos as “pests.” It’s also the noise.

The study found that the further armadillos got from Fayetteville, the more active they were during the day. Closer to the city, though, the armadillos were more active in the quiet of the night, when humans wouldn’t disturb them.

Nocturnal activity may make armadillos safer from humans, but it creates other threats.

For one thing, moving around at night exposes them to nocturnal predators like great horned owls and cougars.

For another, it’s just colder at night.

“Armadillos have a really low body temperature,” DeGregorio says. “When we force them to be active during the coldest parts of the night, during the winter, we’re making them do something that they don’t want to do. There’s a real cost to that. It takes them days and days to recover.”

And yet, they persist. No one knows why they’ve expanded their range so much in recent years — some say it’s climate change, while DeGregorio theorizes human development helped pave their way. Whatever the reason, it keeps bringing nine-banded armadillos to other parts of the United States.

And they’ve accomplished this spread in spite of their other … challenges.

“They’re a puzzling species,” DeGregorio says. “One of the things that really strikes you when you start working in armadillo country is kind of how clueless they seem. They have poor eyesight, and when they’re out foraging, they’re so focused on the ground. If you just stand still, it’s not uncommon for them to bump into your legs and then, you know, panic, jump in the air, then run away.”

None of their shortcomings seems to stop them from surviving, thriving and contributing to their surroundings.

“Not only are they surviving in the wild — they’re also extremely adaptable,” he says. “They’re spreading their geographic range at a remarkable rate, and they’re really changing the environment to the benefit of other animals around them.”

Will this research help challenge people’s unfair attitude toward armadillos? “I would love to see that perception change a little bit,” he admits.

It has certainly shifted his own idea of the species, DeGregorio says. He used to see armadillos as “this kind of goofy, overlooked animal.” Now, he says, it’s changed to “Wow — they make a meaningful difference for the ecosystem.”

Could Cleaning the Tigris River Help Repair Iraq’s Damaged Reputation?

One man’s mission to remove trash from the polluted river in Baghdad has inspired a nationwide movement that shows how environmental efforts inspire peace.

The sun beat down on hundreds of Iraqis who met on the banks of the Tigris, in Baghdad, to clean the river.

They gathered this past April under the banner of “Clean Iraq,” a grassroot movement organizing weekly cleanups. It was founded in February by Murtadha Al-Tameemi, a software engineer who grew up in Baghdad but has been traveling the world for the past few years.

“When I came back to Baghdad after being away for a while, I wanted to enjoy the sunset by the river,” Al-Tameemi tells me. “But when I arrived, I could not help noticing the trash that ruined the beautiful nature.”

He started going to the riverbanks every day to pick up trash, and he spread the message on social media. Soon other Iraqis started getting involved. Now, every time there’s an event, several hundred volunteers participate.

He only expected to spend only a few weeks at home, visiting friends and family, but when his project took off he decided to stay longer to oversee it.

The April event, though it was hard work, carried a welcoming and friendly atmosphere. People got to know each other a bit, making a seemingly tedious activity enjoyable while making visible progress. With every hour I spent by the river, I saw garbage bags piling up at the water’s edge.

Similar cleanup events take place at rivers and creeks around the world, but in Iraq this initiative is something new. Al-Tameemi says he believes it has the power to drive positive change well beyond the environmental benefits — it could help transform the image many people have of Baghdad and Iraq as a whole.

But I couldn’t help but wonder: Is the movement making a real change, or is the destruction of the Tigris irreversible?

An Ancient River Suffers From Modern Pollution

For centuries the Tigris has been the lifeline of Iraq. Ancient civilizations settled around the river, boosting trade, urbanization and economic growth.

Historically it was also a symbol of the country’s prosperity. Iraq used to be one of the water-richest states in the Arab world.

Now, however, the pollution of the Tigris River has reached levels so high that those who rely on its water are at risk of contracting life-threatening diseases.

For decades Baghdad has produced more sewage than its three main wastewater-treatment plants can handle — about twice as much every day. A study published this April in the journal Water found that the Tigris in Baghdad contained unhealthy levels of fecal coliform bacteria — about three times what the Environmental Protection Agency considers safe for domestic water supplies in the United States.

A paper published in 2020 in the Polish Journal of Environmental Studies identified severe pollution of Tigris’s water as “one of Iraqis’ major sources of cancer.” And a 2017 report published by Save the Tigris, a network of civil society organizations working together to ensure safe access to water for the people of Mesopotamia, found that “every 24 hours around 400 children were being admitted to Baghdad’s Sadr Hospital with diseases caused by polluted water.”

Inappropriate sewage treatment is just the tip of the iceberg, however.

After ISIS gained control over parts of Iraq in 2014, extremists would regularly demolish dams and poison wells to cut Iraqi forces off from clean water and coerce local communities into obedience. To contaminate groundwater, ISIS would release oil or metal debris into outlets such as the Tigris.

As if that wasn’t bad enough, ISIS fighters would also dump the bodies of their victims into the river. During the war and in months following, corpses washed up on the riverbanks downstream from Baghdad or Mosul. Hundreds of undiscovered bodies stayed in the water and decomposed, contributing to the pollution.

ISIS also targeted oil wells in towns close to the Tigris, spilling crude oil into the streets and river. Even when attacks did not directly target oil installations or water infrastructure, explosions would damage nearby sewage networks, pipelines and water-treatment plants.

It’s been five years since the war against ISIS officially ended, but more than 1 million Iraqis remain what’s known as “internally displaced persons” living in informal settlements. In Baghdad alone, there are more than 1,000 informal settlement areas that lack sanitation facilities and sewage disposal. These displaced people often have no choice but to dispose of their waste directly into the Tigris River.

And it’s not just these internal refugees. In a country that lacks proper strategy for waste collection and disposal, throwing trash into the river has become a common practice.

Can the Tigris and Its People Be Saved?

Experts say the Tigris is dying and requires urgent action.

Last November Cascades — a consortium established to examine how cascading climate change effects can cross international borders — published a study of the Euphrates-Tigris basin which found that ”the gradual deterioration of water quality is rendering a significant proportion of water unusable.” The researchers said Iraq urgently needs to reduce the sources of water pollution and use its water supplies more efficiently.

Unfortunately no government projects currently focus on putting an end to the gradual destruction of the river.

A post shared by سفراء النظافة (@clean.iraq)

But the rapid growth of Clean Iraq suggests that at least some Iraqis themselves want to mobilize and work together to restore the Tigris’s glory. Already some 30,000 volunteers have contributed to cleaning the river. The first cleanups took place only in Baghdad, where they’ve managed to fill more than 24,000 garbage bags with trash found around the river and cleaned a stretch of three kilometers. As the initiative gained publicity, citizens of other governorates expressed interest in joining. With the permission of Al-Tameemi, they started organizing events in other parts of Iraq as well.

Despite their achievements, there’s a risk that the campaign could become stagnant, especially if people start losing their motivation to clean the river.

That could happen if they fail to see any progress. Many of the volunteers I met told me that it’s not uncommon for Iraqis to throw their waste into the river without realizing the harms. Therefore, even as the campaign grows, there will always be people who keep polluting the Tigris.

Cascades’ paper confirmed that, saying Iraq is characterized by “low public awareness on environmental topics.”

And even if all the rubbish is removed from the river’s banks and people stopped adding new garbage, the water is still contaminated with toxins from trash that already broke down, oil spills and industrial waste.

Environmental Peace

Al-Tameemi, recognizing that gap, says he wants to not only clean the river but teach people about the importance of keeping the environment garbage- and pollution-free.

“It’s not just about cleaning the river,” says a videographer named Karrar, who creates content for the campaign’s social media accounts. “It’s about spreading awareness, making a change and bringing people together.”

Theoretically, it might achieve even more for Iraq.

According to a special issue of the journal International Affairs published in January 2021, environmental initiatives like this can play a major role in peacebuilding in conflict areas. Papers in the issue used cases from Colombia, Liberia, Yemen and other countries to show how working together on protecting nature reduces tensions, drives integration and unites members of society.

“Environmental challenges offer opportunities for cooperation,” the editors wrote, “because they transcend political boundaries, may be less sensitive politically than other topics, and may stimulate actors to consider longer time horizons… Cooperation on environmental challenges can be instrumental in building trust and understanding between social groups.”

After decades of tyranny, Iraq finally appears to be stable enough that people can focus on actions such as this. Environmental degradation is a major consequence of armed conflict, so cleaning the Tigris River could be a sign of the country’s cautious recovery.

As part of that, the Clean Iraq movement — which has received global news coverage — could show foreigners that Iraq is open to the world and that it’s no longer a war-torn country where people live amid horror and fear.

“We are always happy to see foreigners in Baghdad,” says Abdul, a participant at one of the cleanup events. “Not many people come here because they think the war is still happening. But Iraq is peaceful now, and it is a beautiful place.”

Time for Solar Energy to Shine

President Biden made waves with recent actions to boost solar manufacturing, but states have been busy, too.

This spring President Biden gave a shot in the arm to solar and other clean-energy technologies with a couple of important executive actions. The move comes at a critical time, since Congress has yet to pass comprehensive legislation needed to help fight climate change.

Fossil fuels still make up the largest share of electricity generation in the United States, but renewables have chipped away at dirty power and now represent the majority of new power sources coming online.

Wind is behind nearly half of all electricity generation from renewables, but a lot of solar is waiting in the wings. Berkeley Labs reports that solar combined with battery storage accounted for 85% of new capacity awaiting grid connection at the end of 2021.

The last decade has been a big one for solar, with a 40-fold increase in electricity-generation capacity between 2010 and 2021.

That has a lot to do with solar panel costs coming down and efficiency going up. In 2010 the price for residential solar was $7.53 per watt — that fell to $2.65 at the beginning of 2021. Over the same time, utility-scale solar dropped from $5.66 per watt to $0.89.

But not everything about solar is bright this year. The outlook dimmed a bit as economic and political forces squeezed the industry.

Federal Action

The first quarter of the year wasn’t a good one for solar — installations fell 24% compared to the first quarter of last year.

One of the biggest issues stems from a Department of Commerce investigation into whether China is skirting import duties by shipping solar components through a handful of southeast Asian nations. That’s led to a threat of new tariffs, which has put nearly two-thirds of planned U.S. solar installations in jeopardy, according to a report from industry researcher Rystad Energy.

It’s put the Biden administration’s climate agenda in peril.

To counter that, the administration in June announced a two-year tariff exemption on solar panels from Cambodia, Malaysia, Thailand and Vietnam as a result of the Commerce investigation.

Those four countries account for about 80% of the U.S. supply of solar modules, which is why most U.S. solar companies welcomed the news.

“The 24-month tariff extension offers some certainty at a time when it is needed most, and it buys some time for industrial clean energy policies like long-term tax credits and manufacturing incentives to be put into place,” reported PV Magazine.

About two-thirds of solar industry jobs in the United States are in the development and installation of projects, with only 14% in manufacturing, according to Canary Media.

Of course, the companies that do manufacture in the United States, like Auxin Solar, weren’t excited by Biden’s action.

But the president also took action to boost domestic production by invoking the Defense Protection Act to kickstart manufacturing of solar-panel parts and other clean energy-related technologies, including insulation, heat pumps and materials needed for power-grid infrastructure.

Additionally, the administration hopes to spur more domestic solar-manufacturing capacity by using the federal procurement process to streamline government purchasing.

Now come a few more critical steps. Congress needs to get to work funding these initiatives, and homeowners and businesses need incentives to start buying the products.

Regional Growth

Action on solar hasn’t been confined to D.C.

Florida scored a defensive solar win, which came from a somewhat unlikely source: Republican Gov. Ron DeSantis, not normally a pal to environmentalists. In April he vetoed a bill that would have set back the state’s burgeoning solar industry by reducing how much money homeowners with rooftop solar get from the extra power they send back to the grid.

In Puerto Rico residents are tapping solar and storage systems on their road to recovery and resilience after a duo of devastating hurricanes hit the island in 2017. There are now more than 8 times as many rooftop solar systems compared to 2016. Much of the growth has been spurred by grassroots efforts, though, and residents say more help from the government and utilities is still needed.

New York, meanwhile, is using the power of the sun to edge closer to its goal of getting 70% of its electricity from renewables by 2030. On June 2, state officials announced contracts for 22 large-scale solar and energy storage projects with enough capacity to power 620,000 homes. It’s the largest land-based procurement so far for the state and will add more than 2 gigawatts of solar and 160 megawatts of storage.

Siting Concerns

A significant advancement came from Maryland, where the state legislature passed House Bill 1039 to exempt solar projects from county and municipal property taxes if half of the electricity they generate goes to low-to-moderate income customers at a cost that’s 20% lower than the base rate of the local utility.

That’s good for climate equity. But the bill had another bonus. The same tax breaks also apply for projects that make use of marginal lands like rooftops, brownfields and landfills, as well as for “agrivoltaics,” in which land accommodates both solar and agriculture.

Maryland’s plan takes a critical issue into consideration: As solar installations increase, where the projects are sited has become paramount.

Massachusetts is making a big push for renewables, but some of that is coming at the expense of important natural areas.

A 2020 Audubon report found that a quarter of land being developed in the state is for ground-mounted solar arrays. Additional research found that most of that development was razing farmland and forest, including in the ecologically important Coastal Pine Barrens.

If current trends hold, 150,000 acres of land will be lost to development for renewable energy in Massachusetts — land that provides other important functions fighting climate change.

The Audubon report suggests a different path forward: “We must encourage the continued growth of the solar energy sector while emphasizing rooftop and parking lot canopy systems rather than ground-mounted arrays that degrade wildlife habitat and other important values of natural land.”

Existing rooftops could meet up to 47% of the electricity needs in Massachusetts. And that’s just the tip of the iceberg.

A report from Environment America found that big box retail stores, shopping centers and malls across the country have a combined 7.2 billion square feet of rooftop space that could help generate 84.4 terawatt-hours of solar electricity each year — enough to power almost 8 million average U.S. homes. The states with the biggest potential, according to the study, are California, Florida, Texas, Ohio and Illinois.

California also has another opportunity beyond marginal land — marginal waters.

This fall, a pilot project to construct solar panels over irrigation canals will begin in Turlock Irrigation District near Modesto. The solar-water combo is expected to be a win-win. The canal water will cool the solar panels, increasing their efficiency, while the panels stretched over the canals will provide shade, lowering evaporation and reducing the growth of aquatic weeds.

If the test project is successful, California has ample opportunity to expand it. Research by University of California Merced found that covering the state’s 4,000 miles of canals with solar panels could reduce evaporation by 82%, save 63 billion gallons of water a year, and generate 13 gigawatts of power.

There’s another huge benefit. Building these arrays over California’s canals could prevent more than 80,000 acres of farmland or natural habitat from being developed into solar projects, according to UC Merced engineering professor Roger Bales, who’s been involved in the research.

“Solar canal installations will also protect wildlife, ecosystems and culturally important land,” he wrote in The Conversation. “Large-scale solar developments can result in habitat loss, degradation and fragmentation, which can harm threatened species such as the Mojave desert tortoise.”

Desert solar development has also endangered desert plant communities, which play important ecological roles, as well as providing cultural resources to Tribes.

While we do need to build more solar, we don’t need to do it in sensitive habitats. If more states — or the federal government — follow Maryland’s lead and incentivize renewable development on marginal lands, we can advance clean energy while not further imperiling biodiversity.

And we’ll need to — we can’t fight climate change without thriving ecosystems.
