The Amazon is the region formed for the basin of the Amazon River and covered by the Amazonian Forest. It is the biggest equatorial forest of the world. The Great Amazon encloses nine countries of South America and an area of 7,5 million km². The Brazilian area represents 66% of this total. The Amazon River, alone, represents about 17% of all the liquid water of the world. It drains one-third of South America.
When the European pioneers arrived in the Amazon, in the 16th century, it was inhabited for a great population of aboriginals. In the beginning of the 20th century, it started a wild deforestation and, today, the ecological balance of the whole Amazon is at risk.
