1) During the vacations I made a trip with my family by rio Amazon. My father is cientifico environmental and had to make some investigations on the state of the forest and the marsh of rIo. This area is very important because the forest produces oxIgeno and absorbs polluting agents. The health of the forest affects the well-being of the entire world. 
2) Nonwise that rio Amazon was so interesting. he is rio but long of Sudamerica and the long second but of the world. Single rio Nile is but long. We disembarked in one of tributary but the important ones, rio Black, that ends at the city of Manaus. 
3) I like much the city of Manaus. it is the great port but of that region. of alli many products of the forest are exported, like the nut of Brazil, the rubber and several classes of hard wood.   
6) Many species of plants and animals that we saw in our single trip live in the forests of the Amazon and today they are in danger of extinction by the destruction of the forest. serious terrible to see them even disappear the anacondas and the piranas!
