Interested in the bison. They enjoyed hunting and wanted the skins to make coats, so they began to kill bison by the the million. Often they look the Skins and some of the meal from the head, and left the rest or the animal there on the ground. White people also killed bison because they thought they were a danger 10 their cattle. You could even pay ten dollars to ride on a train and shoot bison all day. By 1895, there were only 800 bison in North America. In 1902 people took forty-one animals to Yellowstone National Park. Nobody can hunt animals in a national park. So the bison could live there without danger. Now there are about 350,000 bison in North America again. That is very lucky. When there are only 800 animals of one species in the world. It is very easy for the species to disappear forever.
