I think we should walk too school because it is a good exercise. When you get a drive too school your car causes pollution. And pollution causes global warming. Global warming causes the world too get hotter.When the world gets hotter the water starts to evaporate and there will be no water for us too drink. Also global warming causes ice too melt, so in the North and south pole the ice will melt and the people and the polar bears there will lose there there home and might even die. That is why you should walk or bike too school.
