Everyone should take this course, or a course like it. I found the ideas in this course incredibly enlightening to my understanding of the environment and our place in it. There were so many new ideas in this course, it's pretty amazing. Tragedy of the commons, Malthusian collapse, demographic transitions, insolation and weather vs. climate systems, energy conservation/displacement, virtual water, agricultural water efficiency/contamination/limits, types of environmental policies throughout the world and their impacts, etc.
However, the lecturer can often be biased, making many prescriptive assertions; the video background pictures can often cause a strain because they're not distinguished enough from the lecturer; some of the quiz questions can be poorly worded; and last, but not least, is the overcomplicated way in which the course is organized. Otherwise, it's a very insightful course -- answering a lot of questions I had and providing insight into many I never knew about.
