The largest living structure on Earth is the Great Barrier Reef.
Explanation:
- Location: Off the northeast coast of Queensland, Australia in the Coral Sea
- Size:
- Stretches over 2,300 kilometers (about 1,430 miles)
- Covers an area of roughly 344,400 square kilometers (133,000 square miles)
- Composition: Made up of thousands of individual coral reefs and islands formed by billions of tiny living organisms called coral polyps
- Why It’s Living: The reef is a massive ecosystem built primarily by living coral animals, making it a single interconnected living structure visible even from space.
Importance:
- It’s one of the most diverse ecosystems on Earth, home to thousands of species of fish, corals, mollusks, sea turtles, and marine mammals.
- Plays a crucial role in marine biodiversity and supports fishing, tourism, and coastal protection.
- It’s a UNESCO World Heritage Site but faces threats from climate change, coral bleaching, and pollution.
