Essay Title: Polar bears are endangered
Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected ...view middle of the document...

Current population numbers are estimated to be somewhere between 21,000 to 25,000 and severely decreasing. At the present rate of global warming most of the frozen portions of the Arctic may disappear by the end of this century.
There are so many consequences because of global warming and humans polluting. As a result of global warming, the polar bear habitat is getting demolished. The warmer temperatures are melting the ice in the Arctic and North Pole. Polar bears are travelling miles and miles to find ice. Polar bears live, eat, and raise their cubs on Arctic ice, which is breaking up and melting at an alarming rate. Year by year, this problem will get worse and worse. Humans and factories throw away their waste in the ocean and it goes in the water the fish and animals drink. Polar bears eat fish and they are affected by this polluted water as well. Hunters kill many animals including the polar bears and it’s decreasing their population. When polar bear population decreases, other animal populations will rise and the animal chain will change. We should not let global warming take over our species and destroy the animal chain. Polar bears are one of the many animals affected and if there are too many animals affected, the whole animal chain will fall apart. Research shows that, even if steps are taken to reduce emissions now, gases already in the atmosphere will continue to heat up the earth for another 40 to 50 years. Scientific statistics indicate they may suffer extinction by year 2100. We still have many years to make a difference. Global warming should be one of our top priority and we should take action.

Global warming and its resultant climate changes are slowly destroying the earth’s polar regions and everything that depends on it. These regions are home to various animals which are endemic to these places but, they are now struggling to survive and adapt to the changes occurring in their environments, while some may survive, others may become extinct.
