Water Pollution around Us
It goes without saying that our environment is getting worse and worse.We're surrounded by all sorts of pollution,such as air pollution,water pollution,noise pollution,light pollution and water pollution.These pollutions have brought about great harm to our surroundings,causing a large amount of damages and even taking hundreds of lives.Of the all, water pollution is the most serious.
It's well know that water is the source of life and we need water every day.We use it for drinking,bathing,watering crops and so on.Man can't live without water.However,to our big disappointement,water resources have been badly polluted,It's reported that it's now hard to find some pure clean water on Earth.What a problem!
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.
