The lower one is rubbish - will watch the top one when I get a moment (it's almost an hour long...)
The top one is about the science.
I was thinking about some of those poor country's
Wouldn't mind betting lot of those dry places around the world were more than likely once covered in lush forests that were devastated and used up by past and long gone civilizations,maybe some was burnt to make room for farming,and some used for building and construction and heating,some exported to other country's and some used for weapons for war maybe thats why a lot of the rain forests are gone.History often has a bad habit of repeating itself.
