Beyoncé is promoting a plant

Remember all those articles that came out last year advising us to switch to "flexitarian" diets in order to fight climate change? 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.
