Threats to the Tundra

The melting of the permafrost caused by the global warming is making it harder for the native animals to survive. Ozone depletion at the North and South Poles means stronger ultraviolet rays that will harm the tundra. Air Pollution can kill food for animals. Oil Spills kill wildlife and causes significant amounts of damage to the environment. Buildings and roads put heat and pressure on the permafrost causing it to melt. Invasive species such as Argentine grey foxes, Canada Geese, and Canadian beavers are eating off the native plants and animals.
