I've heard this topic a few years ago from TV. In that time, I thought that it's crazy. It's never going to happen to this earth. But right now I am interested about global warming more everyday since the world seems to be changing from before and there are more people paying attention to it. I think it seems to be true that this world is getting hotter everyday. Also the natural disasters are happening more often than in the past. I wish that everyone would give better care to our earth. In my opinion, the pollution is the most dangerous thing and also the plastic products that we use are real bad too. I think if we grow more trees it will be good for the earth and people. Since the trees roots are very good to absorb water. Also the people will get fresh air too. If our earth will flood, I think we should build a big barrage in every areas that there are near to the River and the Ocean. I hope that we will solve this problem soon.
