Booming bison

摘要

Prior to 1600, an estimated 30-60 million bison roamed North America. Before the turn of the 20th century, the estimate dropped to below 1,000. But the strong and majestic animal now numbers roughly 400,000 and the bison business is booming. Ranchers, processors, chefs, environmentalists, diners and retail shoppers have all contributed to the bison's resurgence in its native land, but consumers want more.
