At some time you've got to toss up between cultivating the land for humans or their cars, as well as actually accommodating them. All put pressure on demand for land (let alone Al Gore and his conscience trees).

That's a different issue. There is no shortage of land to meet the current needs of biofuel. Sure there is a spike in demand which needs to be caught up to, but the increase in corn prices is not because we have run out of arable land.
