Sir Paul McCartney wants Britain to adopt the Australian practice of “Meat-free Mondays,” to help the environment.

He told The Grocer, “A lot of people go to the gym on a Monday. With meat-free Mondays, it’s a bit like going to the gym but with the added advantage of protecting the planet.”

Because of the huge environmental impact of cattle rearing and meat production, this would mean that less meat would be eaten, so less animals would be needed to feed the population. Thus, the impact of the industry would be reduced.

McCartney points out that though he is a vegetarian, it’s the UN who is encouraging this action.

“One of the most significant conclusions of the recent report on climate change was that we should eat less meat. This is not the Vegetarian Society that said that. It’s the UN,” he said.
