Just a few years ago it seems that bio-fuel would save the world, now it seems as the world looks to food crops to make ethanol there is a shortage of food on the world market. Countries that rely on vast imports of rice/corn/wheat are finding that the price for these staple crops are doubling or getting so expensive that some countries have imposed restrictions on exports.
While we in the rich countries can afford to spend a few Euro more at the local supermarket, for the vast majority of people around the world a few euro mean the difference in eating at all. I don’t think the people who pushed for bio fuel really understood the problems that would arise from using food for fuel. Even now the EU has allowed farmers that put aside land, to be used to stop the rise of even higher prices next year. It looks to me as if there will be a bumper crop next year… Will that not depress the market then ? so that the following year farmers won’t plant as much ? or will the extra crops be used for making bio-fuel.
I do hope that the summer will be a good one 
At least if i don’t feel the price difference poorer people will. I do think that over the next few years we will all be in for a lot of interesting times.
I think that the whole plan for bio-fuel has to go back to the drawing board!
