 \section{Conclusion}
-A class about Energy and Social policy and the author hasn't mentioned climate change, coal, or solar panels even once!  What is he thinking?  How many tons of carbon does your car release in a year? How many shiploads of iron oxide will we have to dump into the ocean for algae to eat up the equivalent about of carbon?  Every question in a class like this is, to at least some extent, informed by numerical calculation and it's pretty arrogant to assume that ``those students'' don't need to (or can't) do the math.  If you're going to have success talking about numerical calculations, you might as well start with examples that everyone can relate to, and everyone eats!  Along the way you might find fascinating historical questions to investigate.
