I worked in R&D for one of the largest agricultural seed producers in the world for 3.5 years and I'd like you to know that there is no need to worry about food. Using hybrid breeding techniques, corn has gone from an average of 40 bushels/acre to 180 bushels/acre in the past 60 years. And the bulk of that gain was simply from traditional breeding techniques - they've just barely cracked the door on using genetic data to make better/more informed seed selection and advancement. The industry is currently averaging a gain of 4 bushels/acre per year and that is only going to accelerate with the massive amount of money that is being plowed into marker analysis. And it isn't going to stop with corn either. Big-Ag is expanding BIG into Asia, South America and to a lesser degree Africa and a lot of awesome work is being done on Rice, Canola, Sunflower and Sorghum. Those crops will be making some major gains in the next 10 years. Don't let the Malthusians scare you, everything is going to be alright.
