These “natural” disasters affect many animals too. The Polar bear is one among many of the affected animals. The Polar Bear also known as “the great white bear” is the largest bear species in the world, it lives in the Arctic.  This great animal is completely dependent of on a sea of ice for survival however the shrinkage of 15 to 20% of sea-ice in the Arctic is slowly killing its prey, causing the species to die of starvation. The melting ice-caps also mean the polar bear has to travel greater distances without any rest. The number of bears found dead in the water due to drowning has therefore increased.
As a result of the melting, solar radiations that are supposed to bounce back on the ice are being absorbed in the water. Consequently, the water's  temperature around the polar caps are getting higher and melting more ice; it is a circular phenomenon. According to experts, “a rapid, dramatic reduction in greenhouse gas emissions is necessary to prevent the extinction of the species.”
A 15% drop in birth rate has been detected by scientists. This is due to the lack of freezing which causes Polar Bears to lose critical fat reserves necessary for females to produce enough milk for their cubs.
The polar bear could be extinct in 100 years. The Polar Bear is in danger of extinction due to Global warming. These animals are faced with the threat of Global warming everyday, due to dangerous levels of CO2 emitted into the atmosphere by our use of planes, cars and other carbon producing equipment. 65% of greenhouse gases are due to public transport like those listed above. With the Arctic getting smaller and smaller the Polar bear will be the first mammal in the world to lose 100% of its habitat through Global warming.
