biofuel
A biofuel is a liquid that proudly proclaims itself the ecological vanguard, stuffing corn fields or palm oil from farms into the engine's maw. In exchange for the dilemma of food and environment, it gains the magical incantation of "carbon neutral". The ideal that burning it will merely recycle carbon dioxide quietly morphs into deforestation and agricultural sprawl. The more it touts investment in the future, the more it aggravates present hunger and resource wars. The quest for a holy grail that balances environmental protection and economic growth continues today under the roar of tractors.
