the buffalo's survival tale
"In the early 18th century 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?"--From the publisher's web site.
