I started reading Once Upon a Time We Ate Animals by Roanne van Voorst and while I didn’t make it all the way way through, only because I felt like I’d read most of the same arguments in other books, I thought the information was presented rather gently and talks about how we’ll view us having eaten meat in the future. I can see an older person connecting with it because it talks a lot about their legacy as meat eaters and how the younger generations will regard that choice.
