The Comoros archipelago is one of the nations that contributes least to global climate change, but suffers most from its effects. The Union of the Comoros is one of only two countries in the world classified as both a Least Developed Country and a Small Island Developing State. A visit to the island of Grande Comore will impress you with the way the island has been shaped by its natural environment. The dark volcanic rock limits infiltration, and the few remaining sandy beaches are mined for building materials. On Grande Comore, the largest of the islands, the Karthala shield volcano often leaves visitors in awe of nature.
