| The "Lemonade" singer announced the contest to 
				her 123 million Instagram followers late on Wednesday in support 
				of the Greenprint Project, which encourages people to reduce 
				their environmental footprint by eating plant-based meals.
 Beyonce pledged to eat plant-based breakfasts and go meatless on 
				Mondays, while Jay-Z is promising to eat two plant-based meals a 
				day.
 
 The project is the brainchild of Beyonce's personal trainer, 
				Marco Borges, who published his "The Greenprint" book in 
				December explaining his plant-based diet and exercise plan. The 
				singer and her spouse wrote the introduction to the book.
 
 A study in the journal Science last June concluded that avoiding 
				meat and dairy products would be the biggest way to reduce the 
				environmental impact on the planet because of reduced irrigation 
				of farmland, animal emissions, food processing and transport.
 
 Under the contest rules, one fan will get a pair of tickets to 
				one official concert tour by Beyonce and/or Jay-Z for the next 
				30 years.
