you can refer to this composition.With industrial revolution and population growth, human beings destroy more and more nature environment. Unfortunately few people take important on this, most of us only care about what is convenient to us. Today we must play attention to this, otherwise we may move to space one day. Generally speaking, Scientists often defines pollution as “the introduction by man, directly or indirectly, of substance or energy into the environment, resulting in such deleterious effects as harm to living resources and hazards to human health.” Pollution usually classify to three parts: (1) air pollution, (2) water pollution, and (3) noise pollution. The former of two mainly hurt to our body but the last make people couldn’t keep their mind. The most common contaminants come from burning of petroleum hydrocarbon, the using of pesticides and industrial and domestic discharges. Due to those contaminants entering into the environments, we suffer many great problems, for examples, greenhouse effect, ozone hole, acid rain, water eutrophication and others. But we don’t have good policies to deal with them they will persist for a long time. In nature, microbes play a pivotal role in the degradation of waste, often being the dominant factor controlling the fate of toxic material. Before industrial revolution, we didn’t have any pollution, because any contaminants were degraded quickly by bacteria. Today we produce too many synthetic things and trash; bacteria don’t have enough time to decompose them. To solve the problems and save our earth, everyone should take responsibilities to do some things. For instance, in our daily life we must make little litters or governments must make strict laws to ban factories to dump wastes. In order to leave a clear earth to our generations, we should protect our environments as possible as we can.
