Will biofuels always be hopeless?: "Fossil fuel emissions were up to about 8Gt/year and climbing fast.... Plants absorb about 120 Gt of carbon/year and turn it into sugars via photosynthesis (and then onto other materials). This is the gross primary production of photosynthesis in the biosphere."

"I do know that we've reached the point where defending our right to emit carbon on the scale we're doing it is several steps down the moral ladder from defending tobacco companies as innocent of causing cancer. On the contrary, I believe we are committing evil in emitting so much carbon, and we need to change. We are heading for disaster after disaster."
