Global warming

Last Wednesday, we watched a movie about global warming and I felt so sad about what is happening to the earth now. I can remembered when I was young, at my friend's birthday, which is April 16th, we were always doing a snowball fight. It was reall nice, but since a couple years, we can't do it anymore. There is no more snow! I'm very afraid about all this drastic change of the weather. In the movie, they showed us a board which demonstrated the evolution of the weather. If we believe in that board, in a vouple years all the iceberg are going to desapear. I think we really need to wake up and to do something.
