In  Eager: The Surprising, Secret Life of Beavers and Why They Matter, environmental journalist Ben Goldfarb reveals that our modern conception of a healthy ecosystem is wrong, distorted by the fur trade that once trapped out millions of beavers from North America’s waterways. The consequences of losing beavers were profound: ponds drained, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”—including scientists, ranchers, and passionate citizens—recognizes that ecosystems with beavers are far healthier than those without them. Ben, who lives in Spokane, Washington, will share his knowledge about these wonderful animals.
