At the end of March, I attended the American Society for Environmental History annual meeting in Seattle, WA. I gave a slightly shorter and more coherent version of this talk. It’s basically an overview of the project as a whole, which comes with the advantages of trying to map out bigger themes, but the disadvantages of feeling a little too vague and general. I’d like to think there’s more narrative force and structure in the manuscript. I’ve been meaning to convert the talk to slidecast for some time (I get my students to do these fairly regularly, so it seemed only right for me to try to struggle with the format—I need to work on it).
