My concern is about Food Crisis and Biofuels. Obviously, both of them are related to Climate Change.
On one hand, there are a number of starving people in the world, especially in the developing nations. On the other hand, many people in the developed countries feed a lot of grain to cattle to produce meat, and they are eager to have biofuels so that they can drive more cheaply because of the high petrol price today.
I do not think Biofuels are the only way to make the world better. At least, we might have to be vegetarians before using biofuels.
Anyway, what do you think about Bioguels related to Food Crisis on sustainability?
