Firstly ,air pollution,which has a bad effect on the environment,comes from factories,power stations and cars.Lots of factories take pollution to world .for example,In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal.Over 2,500 animals were killed that night,Hundreds of thousands of animals were injured.Many of them injured lost their sight.Next,Chemicals in the smoke from power stations cause a lot of damage.They can travel hundreds of miles in the wind before falling to the ground as rain.Nevertheless this “chemical rain” gradually destroys trees in the forests and kills fish in lakes.In Germany,over 50% of the country's trees had been damaged by the year 1986.Last,Cars are a convenient transportation,but they also cause serious problems.All the time,they are pumping huge amounts of waste gases into the atmosphere.These gases,in turn,cause disease and even death.Therefore,it is urgent that the problems be solved.

What has resulted in the problem? First is industrial pollution.With the development of industry,thousands of the factories have been set up,which realease poisonous gases,water and other waste every day.Second,agricultural pollution.China is a country with a big population.It needs mountains of food for its people every day.So,agriculture is developing rapidly,leading to agricultural pollution. In order to make the crops grow well,farmers use chemicals and fertilizers in great amount.They both do harm to the soil and the underground waters.Third is domestic sewage.As is mentioned above,China has a great population,creating millions of tons of life waste every day.This life waste consists of some harmful materials that pullute the water.
For man's bright future,it's now time that water pollution were stopped.Let's be waiting.
