Peak Soil

George Monbiot makes some good points about fuel sources.

He cites a recent report that Peak Oil is upon us, and although environmentalists and geologists have being warning of this for some time, this new report is written by capitalists, so perhaps now governments may start to pay attention.

Growing biofuels to replace fossil fuel seems to getting a lot of criticism, and Monbiot says that land clearance for biofuels causes a massive increase in emissions, and creates a carbon debt that takes between 17 and 840 years to recoup.

An alternative is to use agricultural 'waste', but Alice Friedemann points out that this will likely result in Peak Soil.
