Environmental Problems and Threats of the Arctic Tundra
- The melting of the permafrost as a result of global warming is releasing gases that have been trapped.
- Ozone depletion at the North and South Poles means stronger ultraviolet rays can harm the permafrost, and in turn the tundra biome.
- Air pollution can cause smog clouds that contaminate lichen, a primary food source for many animals.
- The exploitation of oil, gas, and minerals and the construction of pipelines and roads can cause physical disturbances and habitat fragmentation.
- Oil spills can kill wildlife and severely damage fragile tundra ecosystems.
- Invasive species push aside native vegetation and reduce diversity of plant cover.
