The good, bad and the ugly has to be considered about bioenergy solutions, though what's good for our cars and factories may not be for our stomachs or wallets.
Biofuels may wean us off our fossil fuel addiction, but at a cost: water (and land) that would be available for food production will be diverted to growing crops for biofuels. This has consequences.
One, governements and other actors will have to consider the broader biofuel / food / ecosystem / water implications.
Two, tradeoffs will have to be made, as competition for water will scarcity will have to be balanced with clean energy, increased efficieny in agriculture, greater farm income, and so on.
This complex issue is here to saty, and more needs to be known.
