Where plants grow globally in July, and then in December.

Chlorophyll fluorescence has allowed NASA scientists to map out where you get your produce from (unless from a greenhouse) two opposite times a year.  This is amazing!  The differences are very profound and provide insight into the agricultural world.  I often wonder why my corn comes from Florida and Mexico in May, and then why all fruits come from Costa Rica and Mexico in January.  Geographically, the world's elevations and other features also seem to play an important part in terms of vegetative potential.  Notice the impenetrable mass of the Sahara which prohibits growth anytime, and the extra vegetation around river basins.  This map may confirm what everybody feels, is common sense. However, I applaud the technology which allows man to render an exact display of our green environment.  I love perspective pieces provided courtesy of science.
