ENVIRONMENTAL PROTECTION Nowadays, we face many global problems. And one of them is pollution. So how can we save the Earth? Firstly, we shouldn’t throw the rubbish on the floor，we should throw it in the bin so it can recycle. Secondly, we should save the water. There are many countries in the world are lack of water. So we shouldn’t throw anything into the river or lake. Thirdly, the air pollution is very bad. We must plant more trees and we should ride bike more instead of driving cars. We say ‘mother nature’, so we need to take care of it and change it for better. 本文来源：https://www.wddqw.com/doc/3f6e268e844769eae109ed3a.html
