Basically, I'm a perpetual student. I start by finding a subject I really don't know very much, but that I'm curious about. I learn about it through books in a library, by doing interviews with people who know a lot about the subject, and by going out on my own and seeing for myself what's happening.

The current fast food that we have is inexpensive when you buy it, but the long-term costs of eating it and the long-term costs to society, are much too high. This cheap food, when you add up all the total costs, is much too expensive.

There's also a growing trend toward having gardens in schools to literally show kids where food comes from by having them grow and prepare their own food. There's also a movement that's bringing farmers into schools and creating relationships between local farms and local cafeterias, so that instead of frozen mystery meat, you have fresh produce that's coming from the area that has a name and a face associated with it.

During my school visits, I really enjoy the feedback I get from them much more than anything I might tell say to them.
