More Good News!

Deserts are greening as a consequence of increased atmospheric CO2,
climate is getting back to being what we used to experience during the
climactic optimum and presumably people displaced by desertification of
Africa can re-occupy their homelands.

The reason most of the desert is unpopulated is because there isn't any
water there


The reason for a lot of desert in Africa is over grazing by goats
etc./overpopulation/ ground water depletion.
When the goat die of starvation vegetation slowly returns.
