Global Warming

I think that global warming is a very real problem. animals and other things are starting to die off or having to migrate to different areas because the enviorment they were raised in is changing so much too fast. For example i was flipping through the channels and stopped on animal planet i think and there was a show on polar bears and how they are being pushed to live on land and starting to head south into canada because the ice caps are melting and they cant find any food on the ice. I think going green is something we all need to consider and take part in now.
