These are the folks who I provoked (into thinking, emotion, approval?) with my comment on triple bottom lines. I also said that green jobs are BS.
Besides those inflammatory remarks, I gave them three big economic truths about water (how we get shortages, the problem of missing costs, and the difference between a slide and shift in demand) and then did Q&A.
Here's the 50 minute MP3 [17MB].
After my talk, I listened to the next presentation -- "what do you want the economy to look like in 2050?"
Besides a lot of impossible stuff ("full employment, end of poverty, etc."), I was interested to see how often people mistook political, cultural and biological goals ("honest politicians, zero-waste society, male-female birth control equality") for economic goals. Don't ask the economy to take care of birth control or corruption!
Bottom Line: It's good to talk to students, if only to give them a few more things to think about.
