Biofuels could end up damaging the natural world

the posting goes on to suggest that the problems include some of the following - (directly quoting from the site -

"

• The grain required to fill the petrol tank of a Range Rover with ethanol is sufficient to feed one person per year. Assuming the petrol tank is refilled every two weeks, the amount of grain required would feed a hungry African village for a year
• If ethanol is imported from the US, it will likely come from maize, which uses fossil fuels at every stage in the production process, from cultivation using fertilisers and tractors to processing and transportation. Growing maize appears to use 30% more energy than the finished fuel produces, and leaves eroded soils and polluted waters behind
• Using ethanol rather than petrol reduces total emissions of carbon dioxide by only about 13% because of the pollution caused by the production process, and because ethanol gets only about 70% of the mileage of petrol
