Why we must reduce the pollution in the world

Nowadays, impact on environment pollution is a serious issue. Air and water are very important. Both of them are sources of human life. Air supplies us oxygen to breathe which is used for our body to live. Human will die without water. So that is why we should reduce using cars, reduce waste of water, recycle and reduce using plastic bags.

Firstly, cars release smog containing mostly carbon dioxide. It can make chemical reaction in the atmosphere, causing the greenhouse effect and the “hole” in the ozone layer. People cannot prevent not using cars. It is impossible. But we can reduce using cars. Public transport is the best choice.  Riding bicycles or using solar gas powered car is good ideas as well. Carbon dioxide also causes acid rain. The effect of acid rain on the environment can be very serious. It can destroy plants and make plants cannot carry on the photosynthesis and release oxygen. This is the air pollution from acid rain.

People need to be responsible for the use of water. In the foregoing paragraphs, we have talked about the acid rain already. This effect can change the quality of lakes, rivers and reservoirs. These three areas are the sources of our drinking water, when pollute to water can become acidified. In some developed countries like United State and Australia, people waste a huge amount of water for mulching gardens, swimming pools, hoses running to wash the cars and so on. On the other hand, in some developing nations, the governments do not have enough money for facilities maintenance, so many taps are broken and as a result of water leakage. All of them are the reasons of waste of water.

If people use plastic bags lesser, this could reduce an enormous amount of plastic going to landfill. Plastic going to landfill is a serious problem as it cannot be decomposed easily. Some plastic will need one hundred years to be decomposed. This will cause a great environment threat in the coming years. These reasons are explaining why we should reduce using plastic bags. Use plastic bags for rubbish bin and take our old plastic bags to reuse in the next time when we go shopping.  Moreover, we could bring our own bags when out for shopping.
