People in North America tend to be more cube-like to fit the weather, while the people in South America tend to be tall and thin. The south grows more food than the north. People from South America tend to have darker skin colors than in North America.
I think societies need laws because if we had no laws people would steal, kill, kidnap, etc.. I think laws kind of put a warning to societies to at least warn someone if they do wrong they'll get punished. I think life would be bad chaos if we had no laws governing our behaviors. I am sorry if this is NOT what you needed. I simply gave my opinion!!!
