Read aguanomics http://www.aguanomics.com/ for the world’s best analysis of the politics and economics of water
researchers set up three plots: one replicated the typical Midwestern cycle of planting corn one year and then soybeans the next, along with its routine mix of chemicals. On another, they planted a three-year cycle that included oats; the third plot added a four-year cycle and alfalfa. The longer rotations also integrated the raising of livestock, whose manure was used as fertilizer.The results were stunning: The longer rotations produced better yields of both corn and soy, reduced the need for nitrogen fertilizer and herbicides by up to 88 percent, reduced the amounts of toxins in groundwater 200-fold and didn’t reduce profits by a single cent.
Oh, and there’s a lot of misperceptions of libertarians as laissez-faire fans of natural selection who don’t care about others (in reference to Paul Ryan’s fanfare for Ayn Rand), but that’s wrong. (I’d also say it’s wrong about Rand, since she was more worried about the sins of collectivism and fascism than the actions of free individuals.)
