bilby "If, as some environmentalists demand, it is to happen worldwide, then much of the arable surface of the planet will be deployed to produce food for cars, not people. The market responds to money, not need. People who own cars - by definition - have more money than people at risk of starvation: their demand is effective, while the groans of people at risk of the starving are not. In a contest between cars and people, the cars would win. Something rather like this is happening already. Though 800 million people are permanently malnourished, the global increase in crop production is being used mostly 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."
