Really interesting introduction to sustainability problems & solutions, from local to global (like climate change & poverty). It's also an interdisciplinary subject, so it's useful for anyone of any discipline. There were no tests or finals, it was all project and assignment based, with lots of personal reflection essays and a big group project worth 40%. The prof was super nice and there were a lot of interesting guest speakers and interactive learning opportunities like small group discussions & in-class QR code activities similar to Kahoots.
