The Belize Barrier Reef is a system of coral reefs located along the coast of Belize in Central America. It is the second-largest coral reef system in the world, after the Great Barrier Reef in Australia, and it is home to a diverse array of marine life, including over 500 species of fish, hundreds of species of coral, and a variety of other animals such as sea turtles, manatees, and dolphins. The Belize Barrier Reef is a popular destination for diving and snorkeling, and it is also an important economic resource for Belize, providing income from tourism and fishing. The Belize Barrier Reef is under threat from a variety of environmental stressors, including pollution, overfishing, and climate change, which can lead to coral bleaching and the spread of diseases such as white band disease and white pox disease. It has been designated as a UNESCO World Heritage Site, and efforts are being made to conserve and protect the reef and its ecosystems.
