Hai there :3
I do not know if your question is incomplete for multiple choice, but let me tell you the proper answer.
Climate change, or global warming as scientists call it, has a very negative impact on animals that live in the Arctic, because many animals that permanently live there, such as the polar bear, walrus, beluga, and other animals depend on sea ice for their survival.
In terms of the polar bear, as referred in your question,<u> new research has shown that climate change affects the polar bears' ability to find new food sources. </u>Polar bears lose their habitat, way of living, and food source, all thanks to climate change.
