"Extinction, in biology, the dying out or termination of a species. Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, over exploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers)."
One of the mainly reasons That polar bears are dying is because of climate change, sea ice is melting, which mean that it is hard to get around to get food to survive. So we can help by

Polar bears are very important species and if they were to go extinct, it will affect the environment. The Arctic Fox depends on the polar bear for food they eat the left over seal carcass after the polar bear is done so if polar bear go extinct Arctic Fox might as well. Seals population might increase, but also affecting the fish that seals feed on. We are not exactly what will happen, but biologists have said that polar bears extinction will definitely affect the chain.
If a polar bear comes contact with oil spills it can affect the bear's fur from growing so the bears have to do something to keep themselves warm which means increasing its caloric intake which can be hard since the ice is melting
Polar bears can ingest oil through their fur and eating contaminated prey. Which can cause liver and kidney damage and it has long-term toxicity. Bears can be poison even if a little amount of oil touches their fur.
Around 600 or 3% of Canadian polar bears are hunted by native Inuit hunters. Native people have hunted polar bears for a long time.

There are many ways that polar bears are going extinct, but one of them is climate change. Polar bears depend on sea ice to get their food for the summer and autumn because now that ice melts earlier in the spring and takes time to form later in the autumn like in southern range, like Hudson Bay and James Bay in Canada. Polar bears have to live without food. When polar bear have nothing to eat, they become unhealthy which lead to less reproduction. Scientist believe the reason cub dies because of less food and not enough fat on the mother.
