Monsanto crops bred to thwart western corn rootworms, which love eating corn roots, are no longer are doing their job. The rootworms developed a resistance to the natural pesticide the crops produced and are chowing down.

The alternatives for farmers: buy other genetically modified seeds (which will totally work forever!); spray nastier insecticides; abandon the economic model of monoculture and GMO crops. Guess which one's going to happen. Maybe which two out of three.

Scientists are already working on a new way to make buggies regret they ever thought for a second about eating corn: it's called RNA interference, and it builds genetic code into plants that turns off essential genes of any bugs that eat it. At least, we hope it only applies to bugs.
