They cannot be fed because of LACK of land, Granted, many countries purposelly starve their people, but millions die from lack of food.
Drought causes shortages of local food production.
Drought is specifically a lack of water, not land. Markets compensate for such a condition by offering food imports to an area that is enduring a drought. Glen's point was that there is no global shortage of arable land. You name a number of places where this is demonstrably true. I merely asserted that most grain grown and billions of water used is only for the production of animals for slaughter.
