Tigers are strong and dangerous animals. But now they are in danger.

In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. The number of Siberian tigers (东北虎) was about 300, but now it is less than 22. They’re in danger of dying out. If the government does nothing, we won’t be able to see them in ten to twenty years.

In order to stop people from hunting and killing wild tigers, and in order to make wild tigers more, the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.

However, it’s not enough. Remember that nature is a food chain (链). If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger (饥饿). So the most important thing is to save the animals that tigers eat. In order to protect the wild tigers, we need call on (号召) more people to stop eating, hunting and killing wild animals.

There are many kinds of food in the world. Scientists learn a lot about them. They say that there are some kinds of food people must eat every day. For example, people must eat some green and yellow vegetables. We shouldn’t eat too much meat. People also need to eat some fruits, bread and rice. Of course our bodies need some water and milk.

Scientists say people in different countries and different places eat different kinds of food. They cook food in different ways. Different people eat at different times. In one place, people eat once or twice a day. But in another place, people eat three or four times. The scientists say when to eat and how many times to eat are not important. What we eat is the most important thing.

Nowadays, the world faces two problems. People in some places, for example, in Africa, are not full. Many people are eating junk food. It’s bad for people’s health. So it’s our duty to make everyone full and make everyone healthy.
