As polar bears' population decrease, it creeps ever close to extinction This decrease in the population is due to loss of habitat (floating sea ice). This loss of habitat is caused by which of the following?
A. oil spills from ocean drill sites
B. human cities and houses being built in their habitats
C. Global warming
D. introduced can toads which are out competing polar bears for food

Answer 1

C. Global warming


Because of global warming the ice melts away but the polar bears need the icebergs in order to survive, without the icebergs the polar bears will lead to extinction. If global warming continues the ice will continue to melt and the polar bears won’t have any icebergs.
