Kaibakia Pinata holds the fish he caught in his nets off Bikeman islet, located off South Tarawa in the central Pacific island nation of Kiribati May 25, 2013. Kiribati consists of a chain of 33 atolls and islands that stand just metres above sea level, spread over a huge expanse of otherwise empty ocean. With surrounding sea levels rising, Kiribati President Anote Tong has predicted his country will likely become uninhabitable in 30-60 years because of inundation and contamination of its freshwater supplies.
