Planet Earth

Today we watched a movie in class called planet earth. It was about plains, grass, tundras, monkeys, snow geese, and other stuff. So we had to take notes. Grass covers about 1/4 of the earth. Elephant grass got its name from being as tall as elephants. There were 6 million bison now its one thousand because hunters were hunting them. Elephants arent good at night because there eyesights arent as good as the lions at night. One full grown elephant can feed a pack of lions for a week. Compared to other wild pigs the Pygmy are the smallest.
