Toxicological studies spotlight the effects of pollutants on polar bears and whales, with new research strategies being developed to understand their impact on marine life.
A ten-year study of Chukchi Polar Bears, conducted from 2008 to 2018, found more bears than expected — and healthy ones, too. That’s despite sea ice loss in the Bering and Chukchi Seas.
