In this volume, learn how millions of bison once roamed the American prairieuntil they were nearly driven to extinction. Turn back the clock to the early 18th century, when the American prairies shook under the hooves of nearly 30 million bison. Fast as a horse, tall as a person, and heavier than both combined, they roamed from coast to coast. A century later, people struggled to find a single one left alive. How did the great herds disappear, and what will it take to bring them back? Available in softcover and hardcover editions.
