Just a brief comment on SemBioSys. It's a very clever technology. One of the advantages of using a plant over using animal sources for some of these drugs is that plant viruses and diseases are totally different from animal viruses and diseases, so you can very likely produce safer products.
In terms of productivity per acre, we're going to have to dramatically increase productivity per acre, especially if you're going to go into the things you were talking about, like putting hemp into car seats. If you have a Volvo, you've got hemp in your car from Europe. If you're going to do it that way, if you're going to start using crops to produce biofuels.... China is using much more food, and the demands from China are going to be huge. So people have reckoned we're going to have to double or triple food production just to meet the demands of China and India and the less developed nations to let them have a standard of living like our own. Africa, of course, has massive problems in productivity per acre.
If we're also going to use land for biofuels, the challenges are huge. We're going to have to use new technologies. The only way we can do this is by using new technologies.
