You and I stopped flying at about the same time by the sounds of things. How frustrating to have made that journey to go to see an author whose signing got cancelled! Yes, agriculture is a big one. We joined a climate action group a few years ago, and when I realised how dire the situation was, we were trying to think what we could do, because we were pretty good already - I started darning and patching socks when they developed holes, stopped buying a TV guide, and went vegan. It gets to a stage where it's hard to think what more you can do though. We already bought second hand and made things last until they were broken.
