How do polar bears affect the environment?

Answer 1

Environmental change is affecting the polar bears because of the melting of the polar ice caps and the increasing temperatures. The melting of the ice caps will give the polar bears a lack of habitat and also no place to hunt for pray. And they are evolved to the cold weather so therefore Global warming will cause them to become extinct ! .. Poor Polar bears .

We can reduce this chance by walking or cycling instead of driving a personal car. and if it is to far to walk or cycle take public transport. we can also do this by using renewable energy sources such as solar, tidal and wind power. And not use fossil fuels like gas, oil, petrol etc

There is no tangible evidence of the ice cap melting any more than normal. In the Arctic summer it recedes, then refreezes in winter. The polar bears are not becoming extinct, their population is actually increasing in some populations.

Answer 2

They are top of the food chain in their region, if polar bears don't exist, other animal populations rise. This could create an imbalance, especially if one species rises and out competes another, which could then endanger the other species.

Answer 3

polar bears do not change our enviorment but we can if we reduse reuse and recycle.

Answer 4
