Great Barrier Reef, Australia
The Great Barrier Reef is not what it once was. Stretching for more than 1,400 miles along Australia’s stunning eastern shores, it remains the largest reef system on Earth. It can still be seen from Space, but get closer and it’s clear that this natural wonder is in trouble.
The problem? It’s all down to climate change. The oceans are getting ever warmer and the Great Barrier Reef just cannot cope. You can see it in the colours – or lack of. Once bright and vibrant, the reef is turning white – a phenomenon known as bleaching. As the ocean temperature rises, the reef expels the algae that gives it that characteristic colour.
Bleached coral cannot reproduce, which means that the Great Barrier Reef is not growing as it once did. More than half of the reef is believed to have died and there’s an 89% decrease in new coral growth. Like to see this breathtaking place before it disappears? Don’t leave it too late.
