can we grow enough to feed the world with permaculture

I just noticed today an interesting post on the question of the resilience of the food system, and the comments involved a discussion between Toby Hemenway and the author. Basically the article looked at one of Hemenway's posts on the food system's resilience (and whether it could feed the world I guess) and wasn't so sure. I think they both came to a general agreement that it's hard to know whether the food system is actually resilient or not, but that it might be. Anyway, this was it:

How resilient is the food system?

I'm new here so I don't know whether this post will work.

Might be better off starting a separate thread.

I disagree that the food system is the last thing that will fail. Advance notice of a big snowstorm will empty the supermarket shelves. Food was a problem during Katrina. Those are signs of an efficient and brittle system.

Even our government suggests everyone keep a 2 week supply of food on hand.

I have removed a bunch of stuff from this thread.

And .... this topic is just too political for my tastes for what I want for these forums. Folks that need to discuss this stuff can take it up in other spots.

I've decided to make this thread available for folks to see - especially since so many people were itching to see what Toby had to say.

My position is very much aligned with Sepp's: with permaculture we can feed a lot more people. And we can reverse desertification. And, at the same time, food is not the only issue with overpopulation.

Sorry some things had to be edited out of this thread.

Since the overpopulation issue is so charged for lots of folks, let's focus this thread on feeding the world as best we can with its human population.
