Ask HN: Do you care about sustainability (and how does it show at work)?

I'm a computer science student in University and I've developed a passion for sustainability over the past few years. Bottom line is that I want to make positive social, environmental, and economic contributions to the world in my professional life. Do any other HNers share similar goals? Is anyone achieving this now and, if so, how specifically does it show at work?

I know the term "sustainability" is super broad but, for the purposes if this discussion, I think that's okay.

Right now, my particular interests are in collaborative consumption and education. It would be nice to hear what specific components of sustainability you are interested in as well.
