The World Health Organization（世界卫生组织） says air pollution kills about seven million people around the world each year. Even if polluted air does not kill us， it can make us very sick. However， breathing dirty air may do more than hurt our body. It can also affect our brain and our ability to think.

A new study shows that air pollution can cause a “huge” reduction in our intelligence（智力）. The researchers reported that long-term exposure（暴露） to air pollution could affect a person’s mental ability in two areas： language and Maths. Xi Chen， the researcher of the Yale School of Public Health， led the study. He and his team found that breathing polluted air could reduce a person’s education level by about one year. Xi said that the effect generally was worse for those over 64 years old， for men and for those with little or no education. “The older people are more affected. And

we find， quite interestingly， men are more affected than women. And people working outdoors are more affected than those working indoors.” The researchers noted that the effect of pollution on the language ability was even more serious as people aged， especially among men and the less educated.

四
Why were language skills more affected than Maths skills？ There are two main kinds of tissue（组织） in the brain： white matter and grey matter. White matter is more connected with a person’s language skills， while grey matter is connected to our ability to solve Maths problems. Studies have shown that air pollution has a great effect on the white matter in the brain， but not the grey matter.
Xi said that air pollution did affect the Maths skills just not as much as the language skills.

When we burn fuels such as petrol and coal， we produce a gas called carbon dioxide（CO2）. Too much of this gas pollutes the atmosphere， and causes it to keep in too much heat. As a result， the Earth’s temperature is increasing. This causes sea levels to rise， and in the future may cause cities to disappear.

Cutting down forests
3. F This makes the greenhouse effect worse because trees take in CO2 and produce oxygen. Cutting down trees also destroys the homes of the animals that live in the forests， and causes the surface of the soil to be easily destroyed by rain. This can cause floods and even more damage to the environment.

In many countries of the world people are saying， “We must do something about our rubbish. We don’t want our world to become one big landfill site（垃圾填埋场）.”
In Ireland the government was very worried about plastic bags so they decided to make people pay for them. Since 2002 Irish people have been paying for the bags they take home from the shops. Of course， they soon stopped buying new bags and started taking bags with them when shopping.

Some countries have made even bigger changes. In 2006， the people of Zanzibar decided to stop making plastic bags. They were worried the bags were killing sea animals. They also said nobody could bring plastic bags into the country. Soon there were no plastic bags in the place.

One of the most exciting recycling ideas is Freecycle. It has grown around the world. People join a Freecycle group because they are looking for things or have things that they want to give to other people. Perhaps they have a chair they do not need any more， or they want a camera. They leave a message on the Internet to tell people what they want or what they are going to give. Nobody buys or sells anything—people give things to other people who want them. It is a good idea because it recycles useful things.
Recycling is important and sometimes it is exciting too， but it is only one part of the answer. Using less and reusing are also important answers to the problem of rubbish.
