The University of Michigan has become the second major university to ban sales of Coca-Cola products on campus because of concerns over labor practices in Columbia and environmental practices in India . New York University imposed a similar ban a few weeks earlier. U-M is one of several institutions pressing the beverage producer to authorize an independent review of its practices in Columbia and India . The university said it is prepared to resume selling Coke products once the impasse is resolved. The decision was widely covered by print and electronic media.
