Because Earth is getting warmer.
Melting sea ice is a threat to the polar bears because without the sea ice the polar bears predators will see them and swim away.
Melting Icecaps are where the polar bears used live. If they have to swim farther distances to get to a resting spot, then they are going to be more tired and will drownd because of exuastion
Due to the melting of polar ice caps, where they live, there habitats are being destroyed and they are ending up in the ocean.
They're going to die out, because if it keeps melting, the polar bears will have no ice to live on. And eventually, they are going to die out soon.
ice is melting and there is no place for polar bears to mate and rest after feeding
yes because they live on ice and now thay have to adapt to their fast changing surroundings which they are finding it hard to.
THey live in the polar ice because their fur and they are used to that temperature
probaly because global waming which is melting the polar ice caps
Right now, polar bears depend on humans. The habitat of the polar bear is decreasing. Because of global warming, the ice is melting. Polar bears are dying off because they have to swim long distances to get to ice.
global warming, melting of sea ice...
I'm not sure, but I think Alberta isn't cold enough for the polar bears. Also, there might not be enough ice caps in Alberta for the polar bears to live off of. People talk about how the polar bears are struggling to survive because global warming is melting all their ice caps. Many times, if there aren't enough ice caps, the bears can't find food or survive.
