Put 2 February in your diary! It is World Wetlands Day! It marks the date that the

Convention(公约) on Wetlands was signed(签署)in1971.This special day was first celebrated in 1997 and it is celebrated every year.

　 The celebration is a call for action. It is a way to show people how important and

useful the wetlands are for people. On World Wetlands Day, people around the world take

part in many wetlands activities. People take trips to the local wetlands. There are talks

about how important the wetlands are. People get together to clean up their local wetlands

Children draw pictures to advertise the day. People also compete(比赛)in boat races.

　 The World Wetlands Day is important! If there are no wetlands, there will be no water for anyone in the future. Wetlands help protect nature and resources(资源)like fresh water. Already, more than 10000 million people in the world do not have fresh water.

　 Many people do not know how important the wetlands are. They can understand why an

elephant or a tiger is important because they are big, beautiful animals. It is much harder for

them to understand how important the animals in the wetlands are. These small animals,

such as frogs and snails, play a very important part in keeping the balance of nature.

　 All plants and animals are part of the food chain(链).If the small wetlands animals

die, some animals in the food chain will have nothing to eat. They will also die. People

need the wetlands to keep the balance of nature in the world. If we do not protect nature

today，it will be gone tomorrow.

What do people do with their old, out-of-date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown out with the rubbish.　　
Some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products. Dell, Hewlett-Packard and other companies now also take back some old computers.　　
In some countries, laws are being passed, too. Computer companies will have to collect and recycle their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.　　
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.　　
The computers then go to schools, charities and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things—and cut down on waste, too.
