Eat or Drive?
Do you prefer to eat your food or burn it
in the gas tank?
The government biofuels incentives and the rising oil price make
producing biofuels increasingly profitable. The land that has been used to grow
food is now used to grow fuels, the food production is shrinking, unlike the
demand for it, and the prices are going up. The growing worldwide number of
mouths to feed, the changing diet from economical vegetarian to less economical
meat eating in China and India as well as the much grown appetite for gasoline in these booming
economies, frequent droughts and floods brought on by the changing climate,
shrinking worldwide fresh water supply all help to drive prices up.
We are talking not only Brazil and Indonesia, Ontario farms are switching to producing corn for fuel with breathtaking
speed. Ironically, this consumes just about the same amount of fossil
fuels in the form of pesticides and fertilisers. As soil getting destroyed by
those, more water and more fertilisers are needed. That will drive the food
prices even higher.
According to the World Bank, “the grain required to fill the tank of
a sport utility vehicle with ethanol … could feed one person for a year”.
Since we do want to both eat and
drive, maybe we should look for another solution? Solar produces 1000x
more energy per acre than soy biodiesel as shown by a 2007 study in Colorado. |
