In the video McCartney, two of his daughters, and the actor Woody Harrelson preach the virtues of going veggie just for one day a week.
“[Vegetarianism] not the total solution, but it’s part of the solution,” McCartney said. “A lot of people have been saying this for a long time but there’s resistance.”
“Particularly when you’ve got someone like Trump who says that [climate change] is just a hoax. A lot of people like myself think that’s just madness so it’s maybe a good time now to try and focus people’s attention and say ‘look, forget about him we can do something.'”
