Challenges facing the Marshall Islands

Tony de Brum is the Minister of Foreign Affairs of the Republic of the Marshall Islands on the challenges facing his nation. The Marshall Islands lie just north of the Equator and is made up from two chains of coral atolls and more than one thousand islets. The sea is rising around the republic and Foreign Minister Tony de Brum is continuously campaigning at world forums for climate change to be addressed as it threatens the existence of the Islands, with many parts barely a metre above sea level. Are densely populated small atolls sustainable?
