Coral Reef Awareness Week Jul 18, 2024

Coral Reef Awareness Week

Blooming pillar corals, green sea turtles, and colorful reef fishes—welcome to the underwater universe of coral reefs. They are formed by tiny marine organisms called coral polyps, which create vast colonies housing many species. As we celebrate their beauty and benefits, it"s vital to recognize the lurking threats of climate change, pollution, and harmful human activities.
