Ozone depletion is caused by the release of Chlorofluorocarbons (CFC's). Although the tundra itself does not release enough CFC's into the atmosphere to cause damage, winds carry these harmful gases to the North and South Poles where they collect and deplete the ozone layer. At these poles, where the ozone is thinner, ultraviolet rays are strong and might cause damage to plants and wildlife in the tundra as well. Still scientists are unsure exactly how the extra ultraviolet rays will harm the tundra.

Air pollution is also a huge threat to the tundra because of the influence outside winds have on it. Pollution from factories in Russia, other parts of Europe, and the Eastern United States can be carried to the tundra by winds. The foreign pollution forms smog clouds in some tundra areas and contaminates lichen, a large source of food for many animals.
