Nowadays, our enviroment is becoming serously polluted. There are many reasons cause pollution such as: air pollution, water pollution, soil pollution and deforestation. As a student, I think we should keep the enviroment by using 3Rs in ous life ( there are reseu-recycle- reduce). Going to school by bike. Planting more trees arond. Not throwing trash everywhere. If we follow the simple rules not only will we keep the enviroment clean. But also we will live in a happy and healthy life.
