1970 was World Conservation（自然保护）Year. The United Nations wanted everyone to know that the world is in danger. They hoped that people would act quickly in order to conserve nature（大自然）. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man. It is said that there are tens of thousands of kinds of animals in the world, but now many have died out（绝种）. We are changing the earth, the air and water, and everything that grows and lives . We can't live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future？Perhaps it is more important to ask“What must we do now？”The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers and so on. In a small town in the United States a large group of girls cleaned the banks of  11 kilometres of their river. Young people may hear about conservation through a record called“No one's going to change our world.”It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.

Bamboo (竹子) is one of nature’s (自然) most surprising plants. Many people call this plant a tree, but it is a kind of grass.

Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 metres (4 feet) in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.

Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimetres (1 foot) across. This plant also comes in different colors, from yellow to black to green.

Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.

Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting  new buildings and bridges while they are being built.

In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water because they have no money, and their fields often die from no rain and no water. Bamboo pipes  help poor farmers bring water to their thirsty fields without spending a lot of money.
