Beyonce and Jay Z are challenging fans to go vegan in exchange for free concert tickets for life.
The couple have unveiled the Greenprint Project after penning the forward for Marco Borges' new cookbook 'The Greenprint: Plant-Based Diet, Best Body, Better World'. They are giving one lucky fan who pledges to go vegan a chance to get their hands on tickets to their concerts for the next 30 years.
Marco - who is the founder & CEO of 22 Days Nutrition, a plant-based lifestyle solutions company - told vegan news website LiveKindly: "Greenprint is the positive impact we can have on the world (and our health) by eating plant-based meals. It's about getting people to understand the power we have to effect change through our food choices. It is our responsibility to leave this planet better than we found it for all future generations."
