Veganuary, the world's biggest month-long pledge to adopt a vegan lifestyle, aims to receive 350,000 sign-ups for next year.
Last January, a record-breaking 250,310 people registered, as a plethora of top celebrities backed the incentive.
Stars such as Alicia Silverstone, Evanna Lynch, Mayim Bialik, and Joaquin Phoneix have also featured in the latest Veganuary Launch video.
“If you look at the climate crisis or the violence of our food system and feel helpless, thinking 'I wish there was something I could do', you can. Right now. Sign up to try vegan this January,” Phoenix said.
'Don't discount your feelings'
"Do you have a sense that you'd like to switch to a healthier, cleaner, kinder diet, but need more information?" Bialik added.
"Ask questions, try things, do research, and make decisions based on facts, but don't discount your feelings either. Veganuary is a great place to start exploring!"
An advert created by Veganuary is slated to be the first to air on mainstream UK television. However, widespread circulation of the ad is only possible if the crowdfunding total of £40,000 is raised.
"We all know the power of TV advertising to capture people's attention and influence their behavior, so getting the first pro-vegan ad on TV will be a major milestone for our movement," Toni Vernelli, Head of Communications at Veganuary, said in a statement sent to Plant Based News.
"Our crowdfunding campaign gives everyone a chance to play a part in making it happen.
"Thanks to the Big Give every pound donated will have double the impact, but we only have a week to raise the £40,000 needed to get this bold, fresh, and compelling ad in front of millions of people and inspire them to try vegan this January and beyond. Your support could help make history."
