I would like to have a copy of photo that was taken from the air which
I have seen in the past and can't seem to find now that showed the
difference in the amount of trees on Haiti and the Dominican Republic.
Haiti has distroyed all its trees and the Dominican Republic has had a
successful program against deforestation.  Since both countries share
the same island the differences in this picture were very dramatic.

Hi petersmom,

Here you go - 

NASA Goddard Space Flight Center Scientific Visualization Studio:
Haitian Deforestation
"The border between Haiti and the Dominican Republic (D.R.) is more
than just a political boundary. It also reflects the large amount of
deforestation that has occurred on the Haitian side of the border. One
can easily see from satellite imagery the lush forests still thriving
on the D.R. side of the border, which is in sharp contrast to the
Haitian side of the border."

left and the Dominican Republic is the greener area to the right."

the Dominican Republic."
