Read the text carefully and write True or False.

Animals in danger
People have lived on the Earth for many years. They live on different continents in different countries. People depend on their planet, on the sun, on animals and plants around them.
Many animals and plants are disappearing nowadays. Many of them are in danger. Indian tigers and African elephants are among them. People have hunted and killed many tigers in India and a lot of elephants in Africa as tigers and elephants are often dangerous. Tigers can kill domestic animals and sometimes even men. So people are afraid of them and kill them to save their cows and sheep and protect themselves. But people have often hunted tigers for fun and for their beautiful skin. They sell the skin and get money as the prices are high.
The result is very sad. There are few Indian tigers left on the Earth now. Many of them are old and sick. They don`t hunt people but hide from them in deep dark forests. But people have cut down a lot of trees so there aren`t many forests for tigers. African elephants are wonderful animals. They can help men. In the 19th century Africa was full of elephants. But these days there are not many of them except in African parks. Many less dangerous wild animals and birds are also disappearing from the Earth. Modern life is bad for them. The air is not fresh. The water is not clean. Animals don`t have good things to eat and space to live. Their names are in the Red Book. You can find the names of some fish there too.
People must take special care of them all. We must save wild animals. We must find the right balance between land, people and animals. We must take care of nature.

1. People live on different continents in different countries.

3. Indian tigers and African elephants are in danger.
