· The Great Barrier Reef, located off the coast of Australia, is the world's largest coral reef system.
· It is made up of over 2,900 individual reefs and stretches for more than 1,400 miles.
· The Amazon River, located in South America, is the world's largest river by discharge volume.
· It spans over 4,000 miles and flows through the Amazon rainforest.
· Both the Great Barrier Reef and the Amazon River are home to diverse ecosystems with many unique species.
