Obviously most people know the world is growing and we need to increase food production. There are lots of things that will help scientists. It's going to take science to increase the food production enough to feed the world. When we hit nine billion people I think it's twice as much food production as we're producing today in the world. That's not going to happen without science.
Some of the things that are coming, like higher efficiency use of nitrogen fertilizers and also water use efficiency.... I think in the future we're going to be talking about nutrients and water to grow food. Those are the limiting factors that possibly could affect food production in the world.
