I’m just gonna quote the post:

Last fall a group of CCA architecture students, led by Landscape Architect David Fletcher and Rebar art and design studio shared a meal together at a local taco truck for a class assignment.  Our research seminar explored San Francisco’s food and wastesheds. Our premise was that a seemingly simple, familiar food like the taco truck taco could provide visceral insight into the connections between the systems we were exploring.

Turns out it was pretty tough. Big twist, right? Anyway, there was a talk that we already missed, but the chart is still sweet, even at the small size it’s shown. If anyone finds more about the talk let me know. LINK.
