A boy covered in reef-mud stands with other boys in the village of Ambo on South Tarawa in the central Pacific island nation of Kiribati . 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.
