Global Warming

In the movie AL Gore is the former United States vice president and he spoke about a very important and danger problem which is "global Warming".
He also spoke about many important thinks in the movie one of them was the clean water in the river which represent the beauty of the environment. The global warming has many effects to the environment. There are many examples, but the melting ice is one off them, because the water levels rise up about 20 feet. Al Gore showed in his documentary that the peoples are the responsible of this problem, because they are using cars motorcycles and trains to move from a place to another and that makes the CO2 very big in the air. At the end of his movie he mentioned some solution that solves the global warming problem.
I think in the future it going to be a big problem for our children.
