Mind blowing.. Sahara fertilizes Amazon!

Now this is some extraordinary insight. The Sahara fertilizes the Amazon? Yes, and apparently, without dust from the Sahara, the Latin-American rainforest could not survive. Quite counter-intuitive, isn’t it? It works something like this;

The Bodélé depression is a patch of dessert located northeast of Lake Chad (17°N, 18°E), near the northern border of the Sahel. It is known to be the most vigorous source for dust over the entire globe. The dust that this place, about 1/3 of the state of Florida, produces, travels over the Atlantic in the form of sandstorms, to the Amazon Rainforest. It is a natural fertilizer, without with the Amazon could not exist! (source: http://iopscience.iop.org/1748-9326/1/1/014005/fulltext/)

Weird as it may sound, the soil of the Amazon is not very nutrient rich (as this article explains). All the nutrients and fertilizers for the Amazon soil have to come from somewhere else.. From one of the most dry places in Africa! I think it’s beautiful how the earth works, and how we as humans are only slowly beginning to understand its true wonders!

In case you still have some scientific doubts, (I can’t blame ya!), here is the full research paper.
