In the phenomenon scientists call the "Grasshopper Effect," toxic pollutants released thousands of miles to the south evaporate in the warm climate then ride the winds until they reach the cold air of the Arctic where they eventually fall to the earth.
Toxic plankton and plants are consumed by fish and land animals and the pollutants spread up the food chain to Polar bears, seals, and humans.
