In this lesson, let’s learn about what extinct and endangered animals are.
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 some of the extinct animals on Earth.
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 endangered animals on Earth.
Finally, you have to remember that not only animals but also there are many valuable plants which have become endangered.
