Nowadays, the earth,the humans'homeland,is suffering from serious damage , which is caused by humans' activities. By burining fossil fuels,such as coal,oil,natural gas ,we took off green house gases. Many factories took off the polluted water into rivers directly,polluting the envrionment seriously. To earn money ,mang people cut down trees ,causing siol erosion. As teenagers ,we should learn to save energy and protect the envrironment whithout efforts. 希望对你还有用!
