The Amazon Rainforest

Do you know that the Amazon rainforest is very big? It’s about five and a half million square kilometres. You will find the rainforest mostly in Brazil and in other South American countries.

It is very unusual. It’s very dark in it. If it starts raining there, you will have about 10 minutes to find your umbrella. There are so many trees that it can take 10 minutes for the rain to reach the ground.

10% of the known world species live in the Amazon rainforest. 20% of all the birds in the world live there. It is home to about 40,000 plant species and 2.5 million different insect species. The animal types are different: from big to small, from cute to strange looking, from quiet to noisy. There are a number of dangerous species living in the Amazon rainforest, for example the anaconda.

What will happen if all those animals, birds, fish and plants lose their home, their natural habitat? Some animals will move to other places but most of them will die out. Can it really happen? Yes, and it’s happening now. The rainforest is very old and big, but it is getting smaller every day. The problem is that people hunt animals, they cut down trees to make way for farm land. So many species of plants and animals have already become extinct. About 35 species of animals in the Amazon rainforest become extinct every day. Among the animals that are endangered now are the jaguar, gorilla and some others.

There is another problem, too. Trees and plants in the Amazon rainforest give us a lot of oxygen. If we cut them down, we lose this oxygen, and it can lead to temperature rise.

A number of ecological organizations are trying to save the Amazon rainforest. So if you want to save the rainforest on the Earth, do something! The rainforest will disappear at the end of the 21^st century if you don’t save it. Every little can help.
