The Economist from a few weeks ago seemed to be all about the food crisis. It also proposed a solution – use SCIENCE and TECHNOLOGY to breed specifically high-yielding crops. Sounds a little like GMOs…and a little like a bad idea.
Lack of diversity in agriculture, much like in the human gene pool, increases susceptibility to diseases and pests and tends to favor the less nutritious varieties. This solution also causes a loss of traditional crop varieties and seeds (amaranth, anyone?).
There has to be a better solution, but I’ll think of one later.
