In this Feb. 16, 2013 photo, quinoa plants grow in a farmer's field in Patamanta, Bolivia. A burgeoning global demand for quinoa is spurring new cultivation all across Bolivia's western highlands as prices for the Andean "super grain" soar. But agronomists say quinoa fever is running up against physical limits. Quinoa does not lend itself to industrial-scale production and the rush to increase yields is prompting Bolivian growers to abandon traditional agricultural practices, thus endangering the fragile highlands' ecosystem. Bolivia's President Evo Morales will attend a U.N. event declaring declare 2013 International Year of Quinoa on Feb. 20. (AP Photo/Juan Karita) less
