“It was great to speak at COP27 (this is the 27th United Nations Climate Change Options conference, in Egypt Nov 2022). But not so great to go around the stalls, which were nearly exclusively (apart from ProVeg International and a couple of others) talking about fossil fuels. In this vlog, I explore this topic and ask people what they think the single biggest thing we can do to reduce our impact (as individuals) on the climate. Hope you enjoy!”
