It comes after McCartney has spent years encouraging people to stop eating animals for ethical and environmental reasons
Paul took to Instagram to encourage his 3.5 million followers to watch the hit documentary, Seaspiracy.
He joins a long line of celebrities encouraging more people to rethink their eating habits by watching the film, which debuted on Netflix in March.
Paul shared the film’s launch post via his stories.
He said: “Have you seen the incredible Netflix program Seaspiracy? It is a very strong documentary on fishing that everyone should watch.”
Paul also directed followers to the film’s website, which calls for more people to shift to a plant-based diet in order to help the planet.
Paul has long called for people to ditch meat. Moreover, the musician is behind the Meat-free Mondays scheme created alongside his daughters, Mary and Stella.
Directed by Ali and Lucy Tabrizi and produced by Cowspiracy‘s Kip Andersen, the debut vowed to uncover the ‘war being waged’ on the world’s oceans.
It follows the pair as they journey across the world and record the shocking impacts industrial fishing has on marine life.
The team said it will ‘radically transform the way we think about conservation forever’ – and since then, a slew of celebrities have voiced their support of the message.
They include the likes of Kourtney Kardashian, Bryan Adams, Florence Pugh, and Tessa Brooks.
Moreover, the Seaspiracy directors launched a petition urging global leaders to protect the world’s oceans.
Within just two weeks, signatures skyrocketed to more than 500,000 worldwide.
