Vegan singer Billie Eilish has urged her fans to ‘help the world’ as she celebrated Meat Free Monday’s tenth anniversary.

The 17-year-old superstar posted on her Instagram: “I just wanted to say happy birthday to Meat Free Monday.

“I’ve been vegetarian my whole life, vegan for five years. Help the world – I try.”

Meat Free Monday urges non-vegans to reduce their animal product intake and is seen as an important driver in convincing people to transition to veganism.

Last week Eilish launched into a passionate plea to her fans, asking them to wake up to the realities of the meat industry and go vegan.

She urged her 26 million Instagram followers to react to an investigation which reveals abuse at huge dairy business Fair Oaks Farms.

“I keep my mouth shut most of the time about this because I believe everyone should do eat and say whatever they want… and I don’t feel the need to shove what I believe in, in anyone’s face,” she wrote.

“But man … if you can watch the videos that I just posted and not give a f*ck that it’s you contributing by literally eating the creatures that are being fully tortured just for your pleasure, I feel sorry for you.

“I understand that meat tastes good … and I know you think you’re just one person and it won’t change anything if you stop but that’s ignorant and stupid. If you have half a brain, you should know ‘one person’ adds up. Be smarter.”

Retailers lined up to ditch Fair Oaks Farms in Florida after an undercover investigation revealed horrific abuse inflicted on calves.

The investigation from the Animal Recovery Mission showed workers kicking, throwing, beating and burning young cows at Fair Oaks Farm in Newton County.

The farm posted a lengthy apology following release of the footage. It accepted responsibility for the abuse and explained that the workers involved had been fired.
