The biggest thing you can do is understand that every time you're going to the grocery store, you're voting with your dollars. Support your farmers' market. Support local food. Really learn to cook.
We all need to know how to cook. I can buy a chicken and have many meals come from it. Is it affordable? Yes. Cheap? No. I want to pay the farmers the right price for food. They deserve it. They are the most important people in the country besides our teachers.
When I first went to Paris in 1965, I fell in love with the small, family-owned restaurants that existed everywhere then, as well as the markets and the French obsession with buying fresh food, often twice a day.
Create a garden; bring children to farms for field trips. I think it's important that parents and teachers get together to do one or two things they can accomplish well - a teaching garden, connecting with farms nearby, weave food into the curriculum.
