This is completely bogus. The ever-increasing global demand for soy foodstock is already accelerating the destruction of tropical rainforests - how is it all sustainable to burn huge amounts of foodstock that so we can enjoy making the world "a smaller and better place" [1]?
Just for fun - an acre of soy produces 70 gallons of "biofuel", so a square mile of soy plantation can produce around 45,000 gallons of fuel, or enough to fly a 747 for about 10,000 miles. After slashing and burning a patch of rainforest, you get about 3 years of crops, before you need to leave it for around 10 years to "regrow". If all of the Amazon rainforest (2,000,000 sq miles) was slashed and burned for soy plantations, and assuming it can magically regrow in those 10 years, we will get enough fuel over one 13-year cycle to fly 5 billion miles. That is about 1/10th the total airplane mileage in one year. [2]
