Totems of Greater Yellowstone's "bearish" economy. The rarest natural wonders on a planet being increasingly tamed by humans have a worth that only grows over time. Wildlife, by itself, does not create environmental messes that need to be cleaned up and its abundance is what makes Greater Yellowstone stand out in the world. The two most popular animals that people come to see are grizzly bears and wolves, both products of federal protection under the Endangered Species Act. Illustration by Marshall Cutchin
