Did you know that the soil of the aAmazon rain forestrainforest is poor?

Despite its exuberance, the Amazon rain forestrainforest has a poor soil. The nutrients are in the soil's surface and it is composed by a thin layer of humus (leafsleaves, dead things, branches...). This way, the forest keeps itself alive. But deforestation is a threat to the forest, because, if the soil is unprotected and exposed, it is easily leached. This region has a constantly hot and humid climate, which provides its majesty.

The Amazon rain forestrainforest is the biggest rain forestrainforest in the planet, with about 5,5 million square kilometers, of which 3,3 million are in Brazil. It occupies 47% of the bBrazilian territory. It's the region with the world's largest biodiversity. In a few square kilometers of forest there isare more vegetal species than in all of Europe and more animal species than in all of Central America. Only 10% of its biodiversity is known by science. It has a great potential tofor medical and industrial research and applications. Of course it should be a sustainable exploration. Unfortunately, that doesn't always happen. Government fights to combat biopiracy and deforestation, but due to its immensity, it's hard to keep these things away.

You wrote "5,5 million" (and "3,3 million")and used a comma as the decimal separator. In most English-speaking countries, the period is the decimal separator instead (5.5 million). But many English speakers in South Africa use the comma, so "5,5 million" is not wrong, but most English speakers who don't know that will be confused or think it looks strange.

I enjoyed reading this. It's very thoughtful. Thank you.
