Ari Trachtenberg, a BU scientist, piped in that "for mathematics, we invent the axioms. In science, God invents them, and we work on discovering them."
I think that is an excellent distinction, and it may be extensible to a discussion on unsustainability. In industrial agriculture we invent the axioms, in nature, God invents them.
What happens when we try to create an agriculture such as at Polyface Farm, as described so beautifully in Michael Pollan's book, The Omnivore's Dilemma, in which we harness nature rather than fight it. I think this is science at its best: discovering God's axioms.
