【Hard Soap Hard Soap (1977)】

Remember all those articles that came out last year advising us to switch to "flexitarian" diets in order to fight climate change?Hard Soap Hard Soap (1977) Beyoncé clearly does.

Following the publication of a scientific study that advised changing to more plant-based meals in order to keep "the food systems within environmental limits", the singer shared a post on Instagram promoting The Greenprint Project -- a website linked to a diet book recently published by her trainer Marco Borges, for which her and Jay-Z provided the intro.

"Our Greenprint is the positive impact we can have on the world by eating plant-based meals," explains the site, before giving examples of how this type of diet can help the environment.

There's also the chance to win "Beyoncé and JAY-Z concert tickets for life*" if you sign up. (The asterisk explains that one pair of tickets is available, and "lifetime" means up to a maximum of 30 years.)

Seeing as Beyoncé and Jay-Z challenged fans to go vegan earlier this year, the giveaway doesn't come as that much of a surprise.

The possibility of 30 years of Beyoncé will surely drum up some additional interest, though.
