The rainforests

Did you know that...

...some rainforests are olderthan dinosaurs! ...sonie trees in the rainforest are 45 metres tali!

The Amazon rainforest is in Brazil. It's the biggest rainforest in the world. Thirty per cent of the world’s animals and piants live there. There are morÄ™ than two million insect species in the rainforests. But, every day, about 35 species becorne extinct and disappear.

Why? Because people don't protect the rainforests. Every year. they cut down a lot of trees. Last year, they cut down an area as big as Galicia. Smali farmers and big companies cut down the trees for different reasons.

Farmers sometimes want to have space to cultivate food. Companies cut down trees to make paper and cardboard.

If people destroy the rainforests. the consequences will be serious for everybody. That's because the rainforests produce most of the earths oxygen. If they don't produce oxygen, there will be morÄ™ carbon dioxide in the air. If there is morÄ™ carbon dioxide in the air. the world’s temperaturÄ™ will increase. This problem is called 'global warming’.

We must protect the rainforests. We need them now and people will need them in the futurÄ™.
