We mapped out where the drilling could take place — and how it overlaps with the critical habitats of the most sensitive species at risk.

Drawing clear borders around the Arctic Ocean matters for the future of the people who live there — and for the planet as a whole.

The disappearance of a tiny oceanic parasite, researchers warn, indicates that overfishing has caused an ecosystem to fall out of balance.
