The remote Arctic tundra may seem like the last place on Earth human pollution should be causing a problem — yet it’s filled with mercury contamination. That mercury leaks from the soil into rivers and ultimately the Arctic Ocean, contaminating the fish and other sea life that native communities rely on for survival.
