@gungasnake,
Gunga, I have nothing against aquaponics but ultimately it is a far more resource intensive approach to farming when you factor in construction of greenhouses, water filtration systems, etc., and is probably best suited to boutique items like organic Bibb lettuce. Imagine the infrastructure necessary to have greenhouses growing food for 9 billion people in greenhouses.
And even if you did pack the world's population into Texas, that only buys you a few years, as that population doubles, then quadruples, etc... unchecked. Besides which, it's a fallacy to think that scenario could work in any way without a fairy godmother who delivers food and energy to everyone. The reality is that you would need farms beyond Texas producing the food those people will eat... about as many or more farms as there are now. Those will be tended by farmers. The farmers will likely want Walmarts to shop at and hospitals to tend their wounds, and some restaurants to choose from. And then there are energy workers, water and sewage workers, their homes, their children's schools.... Oh yes, that's infrastructure. So the US Midwest looks pretty much like it does now under your scenario, as does much of the rest of the world.
And by the way, reversible temporary sterilization applied to everyone isn't eugenics, you should look up the term. Reversible temporary sterilization is "birth control" and birth control pills are also a form of reversible temporary sterilization.
Quote:The entire human population of the world could fit in Texas and it would not be overly crowded. The Earth could easily support 100 times its present human population, it's a pure question of infrastructure. From where I sit, the future of food production looks more like aquaponics than like GM foods.
