Leaders warn on biofuels and food

Today, on the BBCNEWS:

Speaking at the UN in New York, Bolivian President Evo Morales said the development of biofuels harmed the world's most impoverished people. And President Alan Garcia of Peru said using land for biofuels was putting food out of reach for the poor.
Meanwhile UK Prime Minister Gordon Brown is hosting a meeting to discuss European policy encouraging biofuels.
But as food prices climb worldwide, there is a fear that development of biofuels could reduce the production of badly-needed basic foodstuffs. The global prices of wheat, rice and maize have nearly doubled in the past year, while milk and meat have more than doubled in price in some countries.
Such rises, combined with high oil prices, are causing increasing political instability in less developed countries across the world. Food riots earlier this month in Haiti, which is highly reliant on imports of food and fuel, led to the deaths of at least six people, including a UN peacekeeper. There has also been unrest in Burkina Faso, Cameroon, Egypt, Indonesia, Ivory Coast, Mauritania, Mozambique and Senegal.

"Biofuels" have shown great promise in weaning the world away from the use of petrofuels. They are supposed to be less polluting, renewable, and all that acreage (primarily corn and soybeans) will go a long way toward absorbing that excess CO2 in the atmosphere.
Not so fast, say critics in the science community. First of all, they say, there's no proof that "biofuels" are any better than their fossil-fuel counterparts when it comes to greenhouse emissions. The other concern is what it may do the planet's ecology. The rush to plant additional acreage for biofuel production could put rainforests at risk, deplete fresh water supplies, deprive wildlife of habitat and eventually, affect the world's food supply.
It comes down to deciding whose needs are greater: the 800 million people all over the world who own and drive automobiles, or the billions of others who survive on a day and already spend half their income feeding themselves.
