What are the four main threats to polar bears?
Threats to polar bears
- Large carnivores are sensitive indicators of ecosystem health. A polar bear at risk is often a sign of something wrong somewhere in the Arctic marine ecosystem.
- Climate change. Climate change, and the loss of sea ice habitat, is the greatest threat to polar bears.
- Toxic pollution.
- Oil exploration.
Why are polar bears endangered by climate change?
Polar bears have relatively high genetic diversity within the species and can disperse over very long distances, suggesting that they may have some capacity to adapt to the ongoing changes in the Arctic. However, their dependence on sea ice makes them highly vulnerable to a changing climate.
Are polar bears still endangered?

What are the effects of climate change on polar bears?
Challenges affecting polar bears The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear’s main prey, seals, which need the ice to raise their young.
Why are polar bears important to the environment?
As one of the largest land carnivores in the world along with grizzly bears, polar bears are known as a keystone species, the apex of the ecosystem. They keep biological populations in balance, a critical component to a functioning ecosystem.
