You may have known several kinds of police, traffic police and street police. But have you ever heard of energysaving (节能) policemen?

A group of 22 of these new policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning (空调) no cooler than 26℃.

 “If everyone sets their air conditioning at 26℃, Beijing will save 400 million kilowatt-hours of electricity in one summer,” said a TV advertisement.

At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20% and increase renewable (可再生的) energy up to 10% from 7% by 2011.

To introduce the public to a green life, last week Beijing held a show on energy-saving technology and products.

“We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it in our daily life,” said Liu Qianguang, an environmental engineer in Beijing.

Have you ever stayed in a hotel? Most Chinese hotels often provide guests(客人) with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don’t have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.
Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources (资源) and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.
Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life:  Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school dining-room, use your own bowl and chopsticks instead of disposable ones.
To protect our environment and our home, it is very necessary and important for us to save natural resources.

You may have known several kinds of police, traffic police, and street police. But have you ever heard of energy-saving (节能) policemen?

One of their aims is to make sure that these places have set their air conditioning (空调) no cooler than 26 ℃.

"If everyone sets their air conditioning at 26 ℃, Beijing will save 400 million kilowatt-hours of electricity in one summer. That's one-third of all the usage of the city in the season," said a TV advertisement.
Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiangsu Province, are going to follow Beijing's steps in setting up a similar police team.
From 1986 to 2005, China met 20 warm winters. It means that Chinese cities have to spend billions of yuan solving the environmental problems every year.
To introduce a green life to the public, Beijing also held a show on energy-saving technology and productions last week. It attracted lots of attention.
"We want to tell people that there are certain ways to protect the environment. Each of us can find right ways to do it in our daily lives," said Liu Qianguang, an environmental engineer in Beijing.
