*. Do humans live in the Amazon Rain forest ?

*. How many people are there?

*. Amazon is the most wonderful place in the Earth. It’s the heart of the Earth.

Not only do millions of species of plants and animals live in rain forests, but people also call the rain-forest their home. The Amazon is the world's largest rain forest. An estimated 400-500 indigenous Amazonian Indian tribes (Amerindians) exist today in the Amazon Rain-forest. There are about fifty of these tribes who do not have any contact with the outside world. These groups have their own society where kids do not go to a formal school but instead, when they are old enough, are taught what they need to know from their elders. Another interesting fact is that some of the greatest threats to these tribes come from people from the outside world.
