Two Main Reasons

Hi my name is Chris H. and in my class of World Cultures I have a lot of things I want to leran but I am just going to explane the two main ones that i would like to learn about. The two are The Global Environment which is about the exploring of the world around us and the other one is The World Today and thats about the early civilizations and the develoment of the world. I want to learn about those cause they sound very interesting and stuff like that.
