"For most of human history, people chased things or were chased themselves. They turned dirt over and planted seeds and saplings. They took in Vitamin D from the sun, and learned to tell a crow from a raven (ravens are larger; crows have a more nasal call; so say the birders). And then, in less than a generation’s time, millions of people completely decoupled themselves from nature."
