The Second Urban Revolution

On friday, we talked about the second urban revolution; which was a large scale movement of people to cities to work in manufacturing. The 2nd urban revolution was made possible by two things

1. It improved food production and created a larger surplus
2. People moved around the places where they worked, creating cities.

There were many steel factories and many people moved around the steel factory.  There was a need for grocery stories, banks, clothing stores and many more; and this is how many cities were created. 

Steels is now not needed because now we have something to replace it, which is called plastic.  Steel factories that were once thriving are called "rust bells."
