biofuel

Just for the record: biofuel - really bad idea. And I reserve the right to say "I told you so".



World population 6 billion; a couple of billion starving and land is going to be more valuable for growing fuel crops to sell to rich countries than growing food crops. The worst of it is that these rich countries will be feeling all warm and guilt free as they drive, fly and heat their way through these new fuels because they're not from the limited fossil fuel reserves (which are tucked neatly away underground and in oceans and frozen tundra and deserts where you can't grow anything anyway) but instead are renewable and carbon neutral-ish as the plants absorb the CO2 while they grow that they release when burnt. If you ignore the energy of harvesting, processing and transporting. And the effect of the fertilisers on the environment. And the fact that food crops find their way back into the food chain much quicker to lock up more CO2 in the next generation. Read James Lovelock if you don't believe me.
