1. The Great Barrier Reef
Listed as one of the original natural wonders of the world, the Great Barrier Reef in Australia has been one of the greatest gifts Mother Earth has given us. It is the world’s largest coral reef ecosystem—so large that it can be seen from space. The site attracts two million visitors a year who fly from all over the world to take in the array of colours and marine life.
Unfortunately, climate change has had a huge impact on the reef. The increasingly high water temperatures kill the algae that gives the coral its vibrant colour—otherwise known as coral bleaching. Though we will soon be losing one of our greatest treasures, there is still time to explore this underwater world.
