If you look at the carrying capacity of agricultural areas throughout the world, their ecological habitats are changing. So I think we're looking at - in our lifetime - great collapses of food services.

People complain that cities don't have fresh, sustainable food, but it's just not true.

We need the humbleness and clarity to see that our food, while benefitting from technological advances, has benefitted even more from free ecological resources: Cheap energy, lots of water everywhere, and a stable climate.
