One of the observations I would make is that if you want to feed the population of the world and preserve species and biodiversity, then I think we have to seriously consider biotechnology as well as other technologies and farming practices.
If you just freeze technology today, as I just referenced, it is going to take a pile of land to produce the same amount of food to feed that population--a pile of land. So you're going to put species at risk. You're going to put water at risk, because you're going to have to look at irrigation to a bigger degree than you might if you had drought tolerance.
I'm with you on the common ground. If you want to preserve species and you want to preserve biodiversity, then we're going to have to look at getting more crop per drop and more yield per acre. Otherwise, we're going to have to plow down a few more grasslands and forests.
