I told you this a few months back but now there is an actual study which says biofuels are hastening the destruction of rain forest.   New Scientist reports that rising prices for palm oil, used in many biofuels, and increasing demand for biofuels in general are causing farmers to increase the amount of acreage dedicated to such crops.   Palm oil agriculture is the leading cause of rainforest destruction in south-east Asia.   Soybean oil is a good alternative to palm oil but this is the leading cause of destruction of South American rainforest.   Biofuels are "one of the most environmentally damaging commodities on the planet," according to Simon Counsell, director of the UK-based Rainforest Foundation.   Looks like we'll need another alternative.
