This was a fairly good course. First, about Bartelmus. He has worked his whole life for economic institutes and various world organizations (such as the UN) working on the economics of sustainable development, and so he brings an incredible knowledge of the subject - both from the viewpoint of detailing the history of the progression of sustainable devt theories, and also from his own experiences of successful ideas.
Sustainable Development: Most economics majors probably are unfamiliar with this subject, so a one sentence summary: it deals with economic, social, and political practices that affect resource depletion and other inputs to the economy, and how our current economic practices affect a future generation's ability to sustain our quality of life. If you aren't familiar with it, that's expected - half the course deals with the fact that standard economic theories do not account for these concerns, and it develops alternative micro and macro models that incorporate sustainable devt.
So, it was an interesting course, and mostly well presented by Bartelmus. Negatively, the readings were scattered, but not horribly so.
Of course, most of the ideas here won't help you when you're stealing money from people while working at Goldman Sachs, so take this course if you are interested in environmental economics, and have a fairly good background in micro.
