I gave a talk last week at the Martin School at the University of Oxford, on the findings of a research project ethical consumption – part of a series this Autumn on Certification and Sustainability. We have a book coming out from the project any time now, in time for Xmas, so this was a bit like a promotional gig. They filmed my performance, and have now posted it on their website. I have never actually watched myself talk before; it’s very odd. I seem to wave my hands around a lot, not sure to what purpose. It’s better in audio only.
