There's been a lot of fuss about the dust coming from the sahara desert. Which is something that is not new at all and happens every year.
Now, I recall watching a video of an old science man saying something along the lines that the origin of life was the air. He mentioned this phenomenon of saharan minerals traveling across the ocean to nurture south american forests. The thing is I can't find this video anywhere and can't remember the name of the guy either. Can you please help me out?
