The increasing on the number of vehicles and factories. Carbon dioxide which helps to increase the earth’s temperature by destroyed the ozone which protect the earth from the sun. we also can’t forget the greenhouse effect. The gases in the atmosphere catch energy from the sun , but without some gases such as ozone which is destroyed by carbon dioxide and methane , heat will by absorbed by the earth . now what can we do to protect ourselves ? first we should learn more about environment . second , we should start saving electricity. By using busses or maybe we can walk instead of using cars. We should also start planting trees.
