Which Central American country is known for the Biodiversity Hotspot of the Mesoamerican Barrier Reef?

Belize is recognized for its significant contribution to the Biodiversity Hotspot of the Mesoamerican Barrier Reef. This region is one of the most important coral reef systems in the world, home to a diverse array of marine species and ecosystems. Belize's coastline boasts the largest barrier reef in the Northern Hemisphere, which provides critical habitats for numerous fish, coral, and other marine organisms. The protection and conservation efforts in Belize have helped maintain its rich biodiversity, making it a crucial area for both ecological research and tourism.

The other countries listed, while they also have important natural resources and biodiversity, do not primarily highlight the Mesoamerican Barrier Reef to the same extent as Belize. Costa Rica, for instance, is well-known for its rainforests and terrestrial biodiversity, Nicaragua and Guatemala have significant ecological areas as well, but in terms of the specific biodiversity associated with the Mesoamerican Barrier Reef, Belize stands out distinctly.
