Bio-fuel - Drink-Or-Drive Scenario?
An interesting article dated May 11th that raised the question of how sustainable and feasible Bio-fuels (Corn & Soy) really is, when you take into account the water demands to grow those crops as well as pollution from soil erosion/degradation. With corn, it's 50 gal of water for every mile driven. Soy jumps up to 150 gal of water.
While just numbers...but for crops grown in thirsty states (CA & CO) is this really a better alternative. The avg person should drink at least one gallon of water/day. We probably use more for showers/sanitation/cooking. Throw on top the increased demand required by these thirsty crops and you're crunching on the amount of water people will be able to access.
I've also been always a little skeptical about Bio-fuels. Running on peat or moss is one thing. Running on agricultural crops that have a demand as a food source is another. Mexico demonstrated not too long ago that increased demand in corn, like any good economy, will increase the prices. And for Mexico, corn is a staple food, used to make all sorts of commodities (tortillas for starters).
I'm on board about being green. I'm not on board making impoverished lives harsher and stripping food supply away.
