I say that the only way that the world can keep up with food production to the levels that are needed with a growing world population, is by the improvement of science and technology, and with the right policies that permit the application of that science and technology. And that includes availability of the improved seeds, fertilizer — how much of each kind of nutrient — and the control of weeds, which is very important, and then, finally, this whole question of credit and policy on pricing. All of those have to be part of the package.
