Elizabeth: You're a real idealist.
Ben: No, I'm a realist. We need to develop crops that can withstand almost anything.
Elizabeth: How are you going to do that?
Ben: Well, we, uh, we take the strongest wheat plants around from the world, cross breed them, then we get the most destructive pests we can find, test the new plants and test again. We're making a lot of progress. We're close to making the strongest wheat the world has ever known.
Elizabeth: And you...when you have it?
Ben: Well I work for a company and they sell it. But it would make food supplies around the world everywhere cheap. Africa, Asia, places where people suffer through cycles of famine. I mean, it might never happen again.
