It's really important for your health, because you will never use as much salt and fat and sugar as a corporation will use cooking for you.

I'm not talking about having to consult Julia Child before you can take a pot off the rack. I think that's something we can all do more and do better.

We could have a greener economy, even a greener consumer economy by changing the rules - whether it's by taxing carbon or trading carbon, I'm not sure what - but in the end there's just a fundamental problem with the sheer amount we're consuming.

Measured against the Problem We Face, planting a garden sounds pretty benign, I know, but in fact it’s one of the most powerful things an individual can do - to reduce your carbon footprint, sure, but more important, to reduce your sense of dependence and dividedness: to change the cheap-energy mind.

But carbon 13 [the carbon from corn] doesn't lie, and researchers who have compared the isotopes in the flesh or hair of Americans to those in the same tissues of Mexicans report that it is now we in the North who are the true people of corn.... Compared to us, Mexicans today consume a far more varied carbon diet: the animals they eat still eat grass (until recently, Mexicans regarded feeding corn to livestock as a sacrilege); much of their protein comes from legumes; and they still sweeten their beverages with cane sugar. So that's us: processed corn, walking.
