In this lesson you can learn about what extinct and endangered animals are. You can also learn about why animals go extinct and why animals are in danger.
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. So, we say they went extinct. Different kinds of animals have appeared and disappeared throughout Earth’s history. Dodo birds, dinosaurs, woolly mammoths are a few animals on Earth, which are in the list of extinct 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. Therefore, blue whales, giant pandas, elephants, gorillas, koala bears and tigers are some of the animals on Earth, which are in the list of endangered animals.
Finally, you have to remember that not only animals but also there are many valuable plants which have become endangered.
