In the past 500 years, hundreds of species of animals have become extinct-they have disappeared from the Earth for ever. In many cases this is because animals have been haunted by humans! Or the areas in which they live have been destroyed by humans. Some animals become extinct in the wild but have survived in artificial setting, such as zoos. If they can successfully breed, they may be taken back to the wild. Przewalski's horse, for example, became extinct in the wild but has since been bred in captivity. Now there are herds of these wild horses in their old home around the Gobi Desert. Other species are defined as "threatened", or in danger of becoming extinct. According to the degree of threat they maybe considered as "critically endangered", "endangered" or "vulnerable".

Here are a few tips which will help to stop animals going extinct:

1) Stop destroying animals home.

2) Give them a suitable environment.

3) Never forget to give food if you have a pet

4) If you have some extra food, provide it to the animals

5) Never hurt the animals.

6) Try least to cut down trees.

I hope this you follow these tips and save the animals!
