Guns, Germs, And Steel

Today in human geo we watched a video named Guns, Germs and Steel. It was about why some people are more wealthy than others. Jarod Diamond's theory is that in Europe and the middle east people had access to wheat and better farm animals than people in other places. All of these things spread on the same line of latitude and eventually spread to the Americas. I think that this is a good theory to the problem because things happen to land and forces people to move so this can cause wealth when the people get more diverse and learn more things along the way.
