Wait a second! Here's the next silver bullet to solve the food problem from the NYTimes. Make as much fuel from plant matter as you want, we have in vitro meat manufacturing on the horizon!
The world has seen the first international conference on manufacturing meat. This is the process, tested so far only at laboratory scale, of growing pork, chicken, or beef through cell culture in vats instead of raising and slaughtering animals.
This may have some merit, BUT how much meat do we really need from a nutritional perspective? I am no dietician, but I do know that we evolved as omnivores; we like many different food items to obtain the nutrients we need for life. It's the protein, right?
My mental model about meat grown in an industrial process (it's what we do now) sans animal leads me down the path of Brave New World. I should be open to the possibilities.
Oh, and the Vanity Fair set will love cruelty-free meat products.
