Global warming is caused by a lot of carbon dioxide. There is a lot of carbon dioxide because people drive a lot, burn wood, and other fuel. If we keep on driving, burning wood, and use our fuel, there will be violent storms. These storms are caused by climate changes.
We can save the world by driving with motor cars and using electric cars, stop burning wood, and use other fuel. You can run, walk, or ride your bike instead of driving a motor car. - James
