Early humans hunted the giant bisons until they were almost extinct. The environment of the Mississippi was great for fishing and gathering. The river attracted deers, bear, birds, and smaller game which made it for those living around the Mississippi to hunt. Native North Americans transformed their local environments to best suit them by using fire to reshape landscapes. The environment benefited the Anasazis by cutting down and transporting more than 200,000 trees to construct the floors and the roofs of the monumental buildings in Chaco Canyon(Davidson 14). The systematic use of fire to reshape forests helped hunters in multiple ways: it increased the overall food supply for grazing animals, it attracted those animal species hunters valued most like large game and by clearing forests of ground debris, fire made it easier to track, kill, and transport game(Davidson 14). The fire also increased the fertility in forests soil. The environment of the coasts of Peru attracted many settlers which then turned into large farming settlements. The environment of the Indus Civilization of Pakistan and Western India have sites of many shells. These shells were made to be used for a multitude of reasons such as: bangles, rings, beads, pendants, containers for dispensing oils or liquids in controlled portions, ladles, spoons and blades(Kenoyer 55/56). It is clear that the environment benefited early
