We all have different priorities. There's no one single set of ethical rules.

High-quality food is better for your health.

Nature abhors a garden.

The shared meal elevates eating from a mechanical process of fueling the body to a ritual of family and community, from the mere animal biology to an act of culture.

It's more important that you eat vegetables, even if they are conventional -- I'm talking about for your health -- then it is until you wait until you can afford organic, or you can find organic.

There are many people who don't do well on a vegetarian or vegan diet, that for them, meat is a very nutritious food. So, I'm not prepared to give up meat. I don't think we need to give up meat, but we certainly need to change the way we raise meat and diminish the amount of it in our diet.

The food system is a very complex beast. There are people who are going to get their food at Wal-Mart or at Safeway; they're not going to the farmers' market. Those people need choices too.
