Biofuels are made from corn and other plants and have been touted as a means of weaning off fossil fuels. Until now, the main argument against biofuels is they take away from the food supply. But what about the water supply? Biofuels require staggering amounts of water: the production of one liter of biodiesel requires 14,000 liters of water.
"Water that is used for bioenergy – whether it be for a food crop such as maize or a non-food crop such as jatropha – cannot be used for food production, for drinking water or for maintaining natural ecosystems. The water footprint, developed by Prof. Arjen Hoekstra, one of the authors of the PNAS article, is a powerful tool for surveying this."

- VOKL is my self-assigned nom-de-blog in the format of a Newfoundland radio call sign. It gives me a name for my voice. And when you say it out loud it's vocal. See? VOKL. This may also reveal a subconcious desire to punnish my readers. I hope you understand. Anyway it's my blog. Start your own blog.
