Polar bears

I have learnt that Polar bears are among the largest predators in the whole wide world. Their fur colors turns from pure white to a yellowish colour resulted from the sunlight or staining by oil from the sea by oil spilling. Their skin, nose and lips are black in color to trap heat from the sun. Their fur is thicker than any other bears. Their furs even covers their feet, for warmth and for friction on the ice.
They are highly depend on thicker ice in the region as it can withstand their weight, polar bears spend much of their time on ice hunting for foods, mating and denning for their homes and to keep them warmth. Pregnant polar bears need to eat a lot in the summer and fall in order to build up sufficient fat reserves for surviving the denning period.
Climate change, causes the loss of thick sea ice and it thins the thick ice. If the ice are thinned, it will not be able to carry the weight of the polar bear. And there will also be lesser and lesser sea ice for the polar bears. Loss of sea ice leads to higher shortage of food. This causes the population of the polar bears to decrease a lot as there is insufficient food for all of the polar bears living there.
This can eventually lead to conflicts between people and bears and lethal removal of the bear. Illegal killing of bears also remains another factor causing their decline.

They should stop all the illegal killings of the polar bears as the population is decreasing and it will cause tham to extinct.
