Environment - current issues:
limited natural freshwater resources, roof storage tanks collect rainwater but mostly dependent on a single, aging desalination plant; a century of intensive phosphate mining beginning in 1906 - mainly by a UK, Australia, and NZ consortium - left the central 90% of Nauru a wasteland and threatens limited remaining land resources

Environment - international agreements:
party to: Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Desertification, Hazardous Wastes, Law of the Sea, Marine Dumping, Ozone Layer Protection, Whaling
signed, but not ratified: none of the selected agreements

Geography - note:
world's smallest island country; situated just 53 km south of the Equator; Nauru is one of the three great phosphate rock islands in the Pacific Ocean - the others are Banaba (Ocean Island) in Kiribati and Makatea in French Polynesia
