Hi
I am being told in "PBS NOVA 2013 Earth from space" that the Amason rainforest is being fed continously with phosphites from the Sahara desert where an ancient lakebed releases diatomites into the atmosphere.
All good and well - you might think. But wait! The same program, as well as other sources claim the Sahara desert to be 6000 years old only. So how did the rainforest in South America survived for millions of years, or otherwise -- just how strong Is the dependence of the vegetation in the Amasonas basin on the Sahara nutrients?
Are there any studies of this, or has this question never been asked before?
Why is this connection being quoted so many times? Is it that important of a discovery?
