Since 1989, Sting has been involved in protecting the Amazon through the Rainforest Foundation which he co-founded with his wife Trudie Styler and last month played a benefit concert for the organization. He’s been involved in other environmental causes like supporting sustainable food, and now he’s putting a camera where his mouth is. The performer is producing a film about vertical farming, according to the Deadline blog, starting with documenting the first one to be planted in the U.S.
Sting and his partner in the project, manager Kathryn Shenker, have purchased the film rights to The Vertical Farm: Feeding Ourselves and the World in the 21st Century. The book by the concept’s proponent Dr. Dickson Despommier, a Columbia University professor, will be released in October by Thomas Dunne Books/St. Martin’s Press.

Because nothing sounds as delicious as produce grown in the clean, crisp air of a busy urban center.
