we can't blame the development of sustainable fuels on any food crisis we may endure. the food crisis is purely down to the greed of western cultures. our current policy of building huge supermarkets and indulging in oversize portions will not only take it's toll on our bellies, but also the developing world.

A potential obesity epidemic dangles over the west like a flabby sword of Damocles because we eat too much, while the rest of the world starves. How do we respond? By burning food. That leaves aside the fact that clearing land for the agriculture of fuel crops leaves it a much less effective area of the globe's surface to absorb carbon. I just don't see anything but bad things resulting from the adoption of biofuels on any significant scale.

I like the style of the article and the fact that you can directly link to the other articles, it reminds me of an independent style of the New Scientist website. This article certainly brings up a good discussion point, but surely what is being grown on the land is up to the landowner, maybe they could use a small part of the land for the farming of crops for the people who actually do the farming. But I fear the land is probably highly mechanised.
