where do we go?

(in which I switch from real science to my imagination--in other words, the beginning of my career as a science fiction writer)



But really trees take in carbon dioxide, which is one carbon atom bonded to two oxygen atoms. During photosynthesis, the energy from the sun separates the oxygen from the carbon and the tree releases the oxygen. So the tree gives us back twice what it gets. But perhaps by this point we've finished exhaling, have walked away from the tree and someone new is standing by and they're inhaling. Inhaling us.
