No, not Martians, of course, but what to call them otherwise? I'm referring to people who are working in the fields of sustainability, efficiency, renewability, etc. I run across a lot of them, and they've all got ideas, perspectives, and stories. So I've decided to try to introduce a few of them via a series of miniprofiles of a type I used to do at the Globe. They're mini because not only are they short, but all the questions, and most of the answers, are 10 words or less.
