Polar bears or Gas?

Over the years, the number of polar bears, along with many other animal species, has decreased. While there are efforts to help these animals, there are many more incidents that add to the causes of the reduction of the number of these endangered species.
Today, the polar bears living in Chukchi Sea near Alaska are facing extinction due to people wanting to get oil from the frozen sea. John Kerry and other critics demand a 3-year period to delay to the Chukchi Sea being sold to different oil companies during which the situation of the polar bears could be understood more clearly.

Global Warming evidently is not the only reason for the extinction of these animals. I find it sad that we can’t even leave one sea alone for these animals to live in. Are we so desperate for gas that we need to go around destroying natural habitats of endangered species and kill these animals? I wonder what animals will be left in, say 50 years?
