The world produces vast quantities of biomass even without cultivation.

Half of all biomass is currently eaten or used. If every bit were available for fuel, it would represent about ten percent of our energy needs.

I can’t believe that number. The world produces vast quantities of forest growth, and other plant growth from algae to the weeds in your garden. We can’t be consuming 1/2 of that.

I, too, find that VERY hard to believe!

Tell that to the folks in Florida & on Lake Victoria battling water hyacinth, or the folks in the Southeast watching kudzu overcome everything in it's path.
