Food vs. fuel

The hungry planet: As stocks run out and harvests fail, the world faces its worst crisis for 30 years

Geoffrey Lean, Independent:

Food supplies are shrinking alarmingly around the globe, plunging the world into its greatest crisis for more than 30 years. New figures show that this year's harvest will fail to produce enough to feed everyone on Earth, for the sixth time in the past seven years. Humanity has so far managed by eating its way through stockpiles built up in better times - but these have now fallen below the danger level.

Cars are a new concern, the worry arising from the present drive to produce green fuels to fight global warming. A "corn rush" has erupted in the United States, using the crop to produce the biofuel, ethanol - strongly supported by subsidies from the Bush administration to divert criticism of its failure to ratify the Kyoto Protocol.

Just a single fill of ethanol for a four-wheel drive SUV, says Brown, uses enough grain to feed one person for an entire year. This year the amount of US corn going to make the fuel will equal what it sells abroad; traditionally its exports have helped feed 100 - mostly poor - countries.
