text: Yeah. Horticulture and agriculture are both engaged in brilliant and fascinating science. It's getting better and more efficient all the time. Current methods are still beyond wasteful, though, and unless we can make crops act more like native plants (little to no extra water needed) I'm skeptical about the future of America's bread baskets. 
  
  I'm thinking the future of farming will likely be in tall buildings dedicated to the task, or using CRISPR to modify crops to grow in salt water. Either that or we need to pump about 1.5 times as much desalinated water as  the Colorado sends down every year, back up from the coast.
