As the world's population continues to grow toward a projected 9 billion people by the early 2040s, the demand for food, fresh water and energy will grow with it. At the same time, supplies (water, in particular) are shrinking. So, does it really make it sense to suddenly accelerate the use of crops to produce fuel to satisfy our seemingly endless demand for energy? Of course not, especially when you consider the amount of water it takes to produce that fuel by current processes. The obvious answer to that question raised by Dennis Avery is an emphatic no.
