In a stable environment a large greedy specialist often does better then a lean thrifty generalist. In a more dynamic environment a lean thrifty generalist does better then a larger greedy specialist.

The problem is our methods of food production: Specialized, concentrated and resource hungry. We might have to become more generalized, distributed and efficient.

[Note: Currently "efficiency" is often mistake to mean "externalizing the cost", "doing less", etc. Here it means "more productive with less resources" and "working smarter not harder"]

Our food lacks any real bio-diversity, it all requires nearly the same conditions to grow. For every joule of food we are currently using more then 10 joule of energy, basically we are turning oil into food. And it's not very mobile.
