Just so you know, the USA isn’t the only country pushing against the edges of its natural resources. Here’s a fascinating article about Saudi Arabia, water, and food. Oil won’t be able to buy everything.
There is a madness about farming in the desert — especially when temperatures are above 100 degrees Fahrenheit, there isn’t a river for hundreds of miles, and the only water is more than a mile underground. The technological bravado is breathtaking, but Saudis are slowly realizing that it cannot go on. That their dream of turning oil wealth into food self-sufficiency is doomed, and they will have to get food from elsewhere. I heard this at a conference on the country’s changing attitude to water, held at the Jeddah Hilton in 2009. … Not far away a huge desalination plant was making the waters of the Red Sea drinkable for the city.
Saudi Arabians have grown colossally rich on the country’s oil reserves. They have grown used to the idea that petrodollars can buy them anything. But Saudis are waking up to the fact that all their wealth will count for nothing if they have nothing to eat.
