Perhaps the most important effect of the new revolution in genetics is that all people may benefit from it, not just those in highly developed nations. Countries that cannot afford tractors, fertilizers, and other expensive aids to modern agriculture may be able to use these things in a simpler, sustainable agricultural system. There are still many things to be done. We must find ways to produce our food with fewer chemicals. One way is to find natural biological controls to do the same things chemicals do now. such "miracles" have happened before, and they have helped agriculture become one of the most progressive, efficient industries in the world.
