Biofuels Will Not Solve Our Environmental Problems.
Biofuels are widely touted as the solution to environmental problems caused by our profligate use of carbon-based fuels. Unfortunately, this miracle-solution suffers from the same limitation as all others: we live in a finite world and can only realistically produce a finite amount of biofuel. If, as some environmentalists demand, biofuels were to be widely adopted worldwide, then most of the arable surface of the planet will be deployed to produce food for cars, not people.
