Extinct and Endangered Animals


 

Extinct Animals

 

Have you ever seen a dinosaur? Have you ever seen a giant mammoth with huge tusks?

 

These animals once lived on Earth, but they all died out and now we cannot see them on Earth. We say they went extinct. Different kinds of animals have appeared and disappeared throughout Earth’s history. Dodo birds, dinosaurs, woolly mammoths are some of the extinct animals on Earth.

 

Why do animals go extinct?

 

  • Due to the climatic changes.
  • Some animals are unable to compete with other animals for food.
  • Some animals are hunted or killed by enemies or predators for their meat, fur, skin or horns.
  • Some animals are changing slowly from generation to generation. There can be small differences among parents, children and grandchildren. Finally, a different kind of animal evolves (develops or grows).
  • Animals lose their homes when people clear land or fill in ponds for buildings.

 

Endangered Animals

 

We can still see blue whales, giant pandas, elephants, gorillas, koala bears and tigers on Earth. But these animals are in danger of becoming extinct. There are not many of them left on Earth. Blue whales, giant pandas, elephants, gorillas, koala bears and tigers are some of the endangered animals on Earth.

 

Why animals are in danger?

 

  • Animals are poisoned by chemicals from farms and factories.
  • Animals are killed by hunters for their meat, fur, skin or horns.
  • People are destroying habitats of animals to build farms, roads and towns.

 

Not only animals but also there are many valuable plants which have become endangered.
