People have lived on our planet for many years. They lived and live on different continents in different countries. People depend on their planet, on the sun, on animals and plants around them. Today let's read and speak about some animals on our planet the Earth.
People have hunted and killed many tigers in India and a lot of elephants in Africa. Why?
Many animals and birds on the Earth are disappearing. Many of them are in danger.
Tigers and elephants are often dangerous animals. Tigers can kill cows, sheep, other domestic animals and sometimes they can also kill men. Some people are afraid of tigers and kill them to save their domestic animals and their lives. But some people have often hunted tigers for fun and for their beautiful skin.1 They can easily sell the skin and get a lot of money as the prices2 are high.
The result is very sad. There are few Indian tigers left on the Earth now. Many of them are old, sick animals. Most tigers don't hunt people nowadays, but hide from them in deep, dark forests. Or they rather hid there earlier, because there aren't many forests for tigers nowadays. People have cut3 down many trees. And the question is: "Have those animals got a future?"
We can ask the same question about African elephants. They 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.
This is the sad story of Indian tigers and African elephants. But 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. They don't often have good things to eat and space to live. You can find their names in the Red Book. You can find the names of some fish there too.
People must take special care of them.
We must save wild animals.
We must find the right balance between land, people and animals.
We must take care of nature
