Thanks for this good, thoughtful comment, Chris.

1. Agreed, but that's not what the corporatists are pushing.

2. There is data that goes both ways on this. Some of the healthiest people alive are carnivores/paleo types.

3. Efficiency isn't the only thing that matters, but I hear you.

4. We could supply the world's protein from a single city of skyscraper food factories, but it doesn't mean we should. I like the idea of taking cues from nature on how many humans there should be.

5. Appear.

6. Pre-historic peoples also didn't live very long. Appeals to nature can always go both ways.

7. I absolutely agree. We need billions less humans and ancient ways of procuring meat that improve the soil.
