In planetary terms, we're all downstream.

If anybody here has trouble with the concept of design humility, reflect on this: It took us 5,000 years to put wheels on our luggage.

Carbon in your body - that's good thing. In a tree, it's good. In the atmosphere, it's a bad. Nature wants to sequester carbon in biota. And when we burn it, we release it. It's the wrong system.
