Every day, as the old saying goes, is Earth Day. But what about World Gorilla Day, Manatee Awareness Day and Wombat Day?

We’ve compiled a full calendar of environmental holidays and awareness days, along with several key eco-anniversaries (both good and bad). They offer multiple opportunities throughout the year to promote awareness of endangered species and Earth-friendly activities, as well as a reminder of what we could lose in the days ahead.
