But if we intend to continue to increase our agricultural output and continue to feed the earth's population then there's no going back, and you can't feed everyone on earth with organic methods. Its hard enough using every trick in the book. Borlaug ( http://en.wikipedia.org/wiki/Norman_Borlaug ) is an amazing guy and anyone who enjoyed this article will enjoy reading about the bio-hacker that fed a billion people and ended mass starvation in India and China by breeding kick-ass wheat and rice that raised agricultural output by seven times since the 1940s!
The solution for Americans: grow your own vegetables! Use plenty of compost, use organic heirloom seeds suitable for your area and spray weekly with dilute dish soap and you'll have minerals a plenty in your veggies and no pesticides. And they'll taste better than anything you've ever had! It doesn't take much land to grow a significant amount of food.
