Reply #42: people will not stop driving cars, that's a given.

it may mean a diverse range of methods to provide power when petroleum becomes too expensive or scarce, but cars in one form or another will be a big part of the social landscape for quite awhile yet. and india and china are pretty much just getting started.

seeing as it's not the first time that humanity has made short-sighted and self-centered decisions, it's a pretty good bet as well that biofuels will be a big part of the mix until cleaner technologies are better developed to be more reliable and efficient. so we might as well find ways to produce biofuels that detracts as little as possible from our food-chain.
