Pollution

The same chemical, organic, and radiological pollutants that contaminate the ecosystems of the rest of the planet pose particular problems for the Arctic. The freezing temperatures of the Arctic, both on land and at sea, prevent pollutants from breaking down into non-toxic constituent components.²⁰ For instance, although the Arctic nations stopped using leaded gasoline more than a decade ago, the measurable lead in fish and wildlife in the area has not declined.²¹ In addition to the cold, the currents which flow to the Arctic from all over the world bring as much as 60% of the pollutants ultimately sited in the Arctic from somewhere else.²² Thus, the failure to include non-Arctic nations in future Arctic clean-up efforts would leave the majority of incoming pollutants unaddressed.
