The world’s coral reefs are home to a quarter of all marine life – and they’re being wiped out. The Water Brothers visit the Meso-American reef, which stretches for over 1,000 km off the coasts of Mexico, Belize, Guatemala and Honduras. This reef attracts an incredible diversity of life, however, 80% of the coral cover across the entire Caribbean has disappeared in the last 30 years. Why is this happening and what can be done to end the destruction? The Water Brothers are determined to find out how both locals and tourists can play important roles in protecting reefs all around the world.
