The environment pollution was more and more serious today. We have no clean water to drink it because of water pollution. And when trees cut down, some animals disappear. There is more and more dirty smoke in the air. People’s health has been great affected by air, noise and water pollution. Many people have died of diseases causing by pollution. In order to live the better life, it’s time for us to protect our world.

Firstly, we shouldn’t throw away rubbish everywhere. And we should recycle, reduce and reuse things, that saves money and reduces pollution. Use things so long as possible. Don’t use plastic bag. Besides, we must plant more trees and stop people cutting it down. We hope our world will be more and more beautiful.

3 . The World Health Organization warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year. Indoor air pollution results from the use of dangerous fuels and cook-stoves in the home. To help fight the problem, the WHO announced, new guidelines aimed at reducing household pollutants.

WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking, heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4. 3 million people die from household air pollution given off by simple coal cook-stoves. WHO officials say indoor pollution leads to early deaths from stroke(中风), heart and lung disease. The main victims are women and girls in developing countries, where they usually stay at home and do the household work.

Carlos Dora is Coordinator in the WHO’s Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene (煤油) fuel indoors. He says opening a window or door to let out the harmful air will not improve the situation. It will only pollute the outdoors.

Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way.

WHO experts note some new, safe and low-cost technologies that could help are already available. In India, you can buy an induction (电磁) stove for about $ 8.00. And in Africa you can buy a solar lamp for less than $ 1. 00. But, this, the agency says, is just a start. It is urging developing countries to use cleaner fuels and increase access to cleaner and more modern cooking and heating items.
