The greenhouse is driven by three things: economy, flavor, ecology. Where ecology is what's being grown in this micro-ecology that can simultaneously thrive and better the soil/rotation, not just the flavor.

If you look at the carrying capacity of agricultural areas throughout the world, their ecological habitats are changing. So I think we're looking at - in our lifetime - great collapses of food services.

I'm not here to say I don't eat vegetables - I do, a lot of them - but, from a soil perspective, they're actually more costly than a cow grazing on grass.

The history of food has never had a better biographer. Required reading for anyone who eats.

I'm not an environmentalist, or a doctor, or a nutritionist.

Conventional agriculture has never succeeded in feeding the world, and it's never produced anything good to eat. For the future, we need to look toward alternatives.

If you just think exclusively about what would be the best tasting or the most profitable, you're just not seeing the big picture.
