SAVE EARTH, SAVE US

     With the development of modern society, pollution caused by human activities is becoming a more and more serious problem.

     Smoke from factories and gases from vehicles are the main reasons for air pollution. Rivers are polluted when people throw waste into them, or when factories pour waste water into them. Modern lifestyle and modern ways of production also cause noise pollution. As a result, many species are dying out. More and more people are suffering from health problems.

     Enough attention should be paid to this problem and measures shou ld be taken. Firstly,we should make laws to prevent factories from pouring waste water into rivers and sending smoke into the air without being dealt with. Secondly, we should raise people’s awareness of the serious problem and call on more people to protect the environment. Only by working together can we help the environment!
