Thanks Brian,

I read something today in an economic investment report (which 
interestingly had nothing to do with biofuels). It stated the 
biggest environmental damages caused by new investments around the 
world were deforestation in Indonesia and burning of the Amazon.

This is likely the effect of biofuels, because these lands are 
being converted to grow sugarcane for ethanol (Amazon) and palm 
oil for biodiesel (Indonesia). I'd much rather go underground and 
take something that's already dead and make fuel (fossil oil) 
rather than have to kill the two most life filled regions on earth 
to get fuel.
