According to Avery, the demand for biofuels threatens moves toward sustainable farming practices and will further destroy rain forests. This is of course true if we continue to pursue current biofuel feed-stocks like corn, soy and even sugarcane. What we need to do is slow down the growth of fuel production from those sources and focus on next-generation sources like cellulose and algae. Of course, even those need to be monitored to make sure we aren't using excessive amounts of fresh water and that the energy input doesn't exceed the output. There are definitely a lot things we need to consider before moving forward too quickly, but moving quickly seems to be the one thing we're so good at.
