I remember a television special in which Charlie Brown and the rest of the Peanuts gang went to a space station. Towards the end the group of kids are looking down on Earth and one states that borders do not exist on the physical globe and what a wonderful world it would be if the political geography matched the "real" geography.
The below Earth-snapshot disproves the children's version of the world.
For this quiz a) tell how it is possible for such a sharp change in agricultural lands in general terms and b) (feel free to turn on labels and zoom around) describe with details what made this change possible.
