Global warming!

OK now the scientists finally tell us what all of us knew already. The earth is getting warmer every year. And it`s our fault! The biggest polluter is the USA, and the USA didn`t sign the Kyoto agreement to help stop global warming because American companies told George W. Bush that it would cost too much. Al Gore is an American politician who nearly became president. He just made an interesting movie about global warming called An Inconvenient Truth. I want to see it. What do you think we can do to help the environment? Tell me your ideas!
