To school to day we have been talking about this theme and watching a short movie. In the movie we could see how the nature is changing. I think this is a really interesting and little scary, because this can have a bad effect on the people after us. If the explanation for this nature change is correct. Then I think it is sad, that we don't take this problem really seriously. I now many people are working for this case, but maybe we must try a little harder. Because we never know what tomorrow may bring.
