Massive biomass plantations don't really help biodiversity. The arable land of the earth that isn't already used for growing food or cities is desperately needed for nature. And as another poster already pointed out, biofuels are horribly poor in terms of energy produced per area. There's simply not enough land on the earth to produce enough biofuel to run our civilization. For a most egregious example of this, see the ongoing disaster in Indonesia where pristine rainforests are cleared away to make room for palm oil plantations, so us Westerners can feel good about using biofuels. Heartbreaking.
