The next big thing

I've heard a couple of interviews with the people involved with Food Inc and it strikes me that as a nation, on the food issue, we're about where we were maybe 10 or 15 years ago regarding global warming - there's a solid minority that is aware of the issue and is advocating for change, but we haven't reach a critical mass, or the issue hasn't quite hit the mainstream. It astonishes me the progress that has been made on climate issues - average people switching to compact fluorescent lightbulbs and bringing their own tote bags to the grocery store. Concern about the climate used to be such a fringe issue and now it's a common and pervasive conversation. I suspect that corporate food production will get into the public consciousness a lot faster than global warming did, because now we're more used to considering these issues, and because people keep getting sick from food.
