Animals are not to blame for anything
There are only about 20.000 polar bears left in the world. So that makes polar bears a species that may disappear in the next century if the current warming trend in the Arctic continues.
They are one of the animals most affected by climate change, but they are not to blame. The damage we are causing them will be the same or worse the worse the damage we will receive.
The main factor endangering the polar bear is the destruction of its habitat caused by Arctic ice melt, i.e., the gradual decrease of Arctic sea ice during the summer and the sustained melting of the Greenland ice sheet.
