Prior to European settlement, the prairies were home to tens of millions of free-roaming bison. The grasses covering these open landscapes serve as powerful carbon traps, with slender leaves removing CO2 from the atmosphere and returning it to the soil through an extensive system of roots. If cornered by a predator, the bison has large horns to ward them off. Nearly 100 species of grasslands birds, for example, evolved in some part to adapt to the nature of the environment created by the hoof print of bison upon the land.
