Paul McCartney's birthday wish this year is for everyone to stop eating meat.
The legendary musician will celebrate his 78th birthday on June 18 and on this occasion he prepared a guest blog post for animal rights charity PETA.
In the video he shared a powerful message asking people to stop eating animals.
He also called his fans to watch Glass Walls - a film he made with PETA 10 years ago.
McCartney said: "All I've ever wanted for my birthday is peace on Earth – including for animals."
"That's why this year, I'm urging fans to watch a video I hosted for PETA, titled 'Glass Walls'. We called it that because if slaughterhouses had glass walls, who would want to eat meat?
"The video debuted exactly 10 years ago. Since then, the public has finally got a peek at what happens inside the meat trade, and the demand for vegan food is sky-high.
"Whether you're worried about diseases that spring from slaughterhouses, the animals who suffer terribly and needlessly, or the catastrophic impact of the meat industry on our environment, please watch this short video and share it with your friends. Thank you."
Glass Walls video has been viewed by more than 20 million people so far.
