"... so few of us can really see what is out there. Even when scads of insistent wildlife appear with a flourish right in front of us, and there is such life always — hawks migrating over the parking lot, great colorful moths banging up against the window at night — we barely seem to notice. We are so disconnected from the living world that we can live in the midst of a mass extinction, of the rapid invasion everywhere of new and noxious species, entirely unaware that anything is happening." — Carol Kaesuk Yoon, Reviving the Lost Art of Naming the World
