I used the same podcast as in move one, but I wanted to focus more on the downfall and transition into modern day.  The Dustbowl and the Great Depression were both very detrimental to the wellbeing of the farmers during the Second Green Revolution, and I want to emphasize this in a move.  Specifically, the Dustbowl ended the years of prosperity that many farmers experienced, and because of this, there was a radical change in how farming has progressed since then.  Additionally, I want to take a look at some famous photos taken of farmers during this time to help convey the point that we have come a long way from being so completely dependent on things like rain.
