How many bison once roamed North America?
A good estimate is that roughly 30 million bison once roamed the grasslands of North America. To the explorers Lewis and Clark, the herds "darkened the whole plains." What happened? People. Massive hunting campaigns brought an end to the seemingly endless herds. Growth of farming and ranching and severe drought caused even more loss.
