McCartney family launches new film ‘One Day a Week’

With appearances by Paul, Mary and Stella McCartney, Woody Harrelson and Emma Stone, ‘One Day a Week’ highlights the damaging environmental impact of animal agriculture and encourages people to help by eating less meat

Ahead of the UN Climate Change Conference (COP 23) next week, Meat Free Monday has released a short film about a huge contributor to climate change that is often left out of conference discussions – animal agriculture.

“There’s a simple but significant way to help protect the planet and all its inhabitants”, says Paul McCartney to camera. “And it starts with just one day a week. One day without eating animal products can have a huge impact in helping maintain that delicate balance that sustains us all.”

With dire consequences for ourselves and future generations, livestock production results in vast amounts of greenhouse gases being released into the atmosphere. It requires increasingly unsustainable levels of precious resources including land, water and energy, and is a major contributor towards global environmental degradation and climate change.

The Meat Free Monday campaign has had an incredible response since its launch in 2009, with many of the world’s leading authorities on climate change endorsing meat reduction as an effective way of fighting global warming.

The campaign’s new film ‘One Day a Week’, largely funded by Bloomberg Philanthropies and produced in collaboration with French film director Yann Arthus-Bertrand’s Hope Production, amplifies this message using the breathtaking aerial photography with which Arthus-Bertrand has become synonymous.

Narrated by Paul McCartney, and with appearances from Paul, Mary and Stella McCartney, Woody Harrelson and Emma Stone, the film describes how the beauty of the planet only exists through a delicate balance of climatic conditions – a balance we are dangerously disrupting through our insatiable desire for animal products.

The film uses Paul McCartney’s own music – tracks from his 1997 classical music album Standing Stone, as well as an unreleased song called Botswana.

Meat Free Monday’s aim is to raise awareness and inspire people to make a change in their diets from an easily achievable starting point.

    Not handling a body part of a dead animal, nor having to store it in the fridge – THAT, for ME, is WO/MENS’ LIBERATION!

  • Virginia Abreu de Paula

    Not only the short film is brilliant, but also all interviews he gave about it. I am glad to see he is asking people to also exclude dairy products on Mondays. I am very thhankful to him and all of you involved in this campaign. I do what I can where I live. Not easy, but I don’t give up. Hey, Merry Christmas and Happy New Year to you all.

    If you all care , and have managed to go meat free for one day, try more days.If you cut out meat all together , then go one more step and become Vegan, as the dairy industry is so cruel. Animals should be here with us not for us. x
