We need a solution to the global warming caused by cars, but biofuel isn’t it. If the production of biofuels is big enough to affect climate change, it will be big enough to cause global starvation.
The market responds to money, not need. People who own cars have more money than people at risk of starvation. In a contest between their demand for fuel and poor people’s demand for food, the car-owners win every time. Something very much like this is happening already. Though 800 million people are permanently malnourished, the global increase in crop production is being used to feed animals: the number of livestock on earth has quintupled since 1950. The reason is that those who buy meat and dairy products have more purchasing power than those who buy only subsistence crops.
