WARNING!For example, if all the polar ice melts and becomes part of the ocean ...…the face of the Earth will change drastically!The sea level will eventually rise 70 meters, and most land areas near the sea will be covered. Not only will the polar bears lose their place to live, but people and many other animals will, too.CO2 is a major cause of global warming. We need to decrease CO2 as fast as possible!
