Like Al gore says in the beginning, one problem is that people think that the planet is so big that something little we do won't affect it at all. I think that the ozone should be protected because the more pollution we release the thicker it gets. Then the thicker it gets the more heat of the sun gets trapped here making it hotter. I think that we should use the pictures that he showed us in the movie as a warning to what might happen in the future. We can see how the glaciers everywhere are decreasing dramatically and very quickly. And if we keep letting the glaciers melt the sea level will rise flooding almost every city that is near the ocean of the country. Like he says in the movie it's sort of up to the U.S. to reduce the pollution since the U.S. is responsible for most of the pollution.
