This May 13, 2014 aerial photo, shows the Rio 2016 Olympic golf course under construction in Rio de Janeiro, Brazil. Grass has been going down for several weeks at the course, which created an upbeat mood as golf prepares to return to the Olympics after a 112-year absence. That changed Saturday, May 31, 2014 when Rio organizers confirmed that a state prosecutor could halt work on the course unless the developer shows it is following environmental regulations and other requirements under Brazilian law.
