This week in science

This week we used the Jenga blocks and some had green representing dead plants, red representing air pollution, yellow representing toxic waste, and blue representing dead animals. It was fun but it was mostly about the damage to our ecosystem and how much of it is caused by use humans.https://s3.amazonaws.com/cs-vancouversun/CommunityServer.Components.PostAttachments/00/00/34/80/35/globalwarming.jpg?AWSAccessKeyId=0TTXDM86AJ1CB68A7P02&Expires=1271222825&Signature=yfFVWGzNppaTRyO%2fFhSGFszo7vo%3dThis is what we cause, is a poor bear our on its own and has to swim as soon as that ice berg melts and will freeze. This is all from driving cars to much and burning oil which eventually creates the image above. Now they are highly endangered. They are the top of the food chain in the Arctic and if they aren't there then a whole bunch of things will be laying on the ground dead.
