Importance of the Tundra
The Tundra plays a large role in the temperature regulation of the planet. As warm air rises from the tropical zone it is cooled in the Tundra causing it to sink back down to the equator. This causes weather and air currents. … the tundra is a key factor in global biodiversity.
What are some threats to the Arctic ecosystem?
The Arctic is under great threat from a multitude of environmental changes induced by human activities, most importantly through climate change, but also through pollution, industrial fishing, foreign species introduced to the area, nuclear waste and petroleum activity.

How does the tundra support life?
Plants and Animals in TundrasMountain goats, sheep, marmots, and birds live in mountain—or alpine—tundra and feed on the low-lying plants and insects.
