How Are Polar Bears Being Affected By Global Warming?
Polar Bear on Melting Ice (by Paul Souders)
Polar bears have evolved for a life on the sea ice, which they rely on for reaching their seal prey. But the arctic sea ice is rapidly diminishing due to a warming Earth, affecting the entire arctic ecosystem, from copepods to seals to walruses. For polar bears, sea ice losses mean:
- Reduced access to food
- Drop in body condition
- Lower cub survival rates
- Increase in drowning
- Increase in cannibalism
- Loss of access to denning areas
- *Declining population size
