effects of glodal warming: Animals

I.m sure most people have heard about the effects of global warming on Polar Bears. One article that I found most intriguing was from Canada. The Grizzly Bears and the Polar Bears are now interbreeding. A hybrid was killed in Canada. It had the features of a Grizzly Bear and solid white fur. Scientists say this will become most frequent, because Polar bears no longer have the large icebergs to climb on. Polar bears used to spend most of their time in the water, but now are forced to stay on dry ground. It is interesting how species that were enemies are now breed to keep from going extinct.
