Biodiesels Fuel Global Warming

Well, this is not news to me as it's been reported before. A new study published in the journal Atmospheric and Chemistry and Physics proclaims that biofuels derived from corn and rapeseed produce more greenhouse gases than fossil fuels.

The study focuses on nitrous oxide, which is 296 times more powerful as a greenhouse gas than carbon dioxide. Scientists found that the use of biofuels released twice as much as nitrous oxide as previously realised.

The growing of corn for biofuel has already raised it's price to levels that reach into the pockets of the poor. In places like Mexico, where corn is a staple and provides 40% of the protein in the average diet, this has had disastrous effects. In addition to being responsible for higher corn prices and the conversion of land formerly used to grow food, now that it is finally official that the switch to biodiesels also will increase the emissions of greenhouse gases into the atmosphere, will the environmentalists finally accept that turning food crops into fuel crops was a mistake?
