Psoriasis & Psoriatic Arthritis (for at least a decade now) have led me to Humira. The results have been super since I began a few years ago. Brown spots, freckle sized, have appeared in the areas where the Psoriasis was. No one has any idea from Drs to pharmacists. .
In 2006, there was 1.15 acres of arable land per person, world-wide (i.e. 7.68 billion acres / 6.68 billion people). By 2039, there may be only 0.59 acres of arable land per person, world-wide (i.e. 7.68 billion acres / 13 billion people). Source(s): http://one-simple-idea.com/Environment1....
Viewing the map showing the U.S. and China superimposed, it can be seen that China has only a slightly larger land area, 3.69 million square miles compared to the 3.68 million square miles of the United States. However, while approximately 40% of the U.S. land can be cultivated, only 11% of China's land is arable.
