Coral reefs are some of the most breathtaking and diverse ecosystems on our planet. They are mostly referred to as the "rainforests of the sea" due to their vast biodiversity.

Coral reefs are not just beautiful, they are also useful, as they maintain the health and balance of our planet, protect coastlines from erosion, support fisheries that feed millions of people, and are a source of new medicines. They also attract tourists and provide jobs in many coastal communities.

Unfortunately, coral reefs are under threat due to climate change, pollution, and overfishing. However, many governmental organisations are working to safeguard coral reefs and protect marine life.

Here are some of the most beautiful coral reefs in the world:
