Scientists strapped GoPro to a sea turtle and made an incredibly powerful discovery from footage

Scientists have long used animals to help them make new discoveries. Most commonly, animals have been used to help identify new vaccines and medicines, but now, turtles are being used in a completely unique way, and this time to help Mother Nature.

This time turtles have been used to help study and understand the impact climate change is having on the Great Barrier Reef, a large coral system in Australia.

What is the Great Barrier Reef?

The Great Barrier Reef is the world's largest coral reef system and one of the most impressive natural wonders. Stretching out over 1,429 miles, and including more than 2,900 individual reefs, it's certainly one of the most impressive natural sights the world has to offer - which is why it must be protected.

Why are turtles being used?

The World Wide Fund for Nature (WWF) are attempting to tackle the mammoth task of trying to protect the Great Barrier Reef.

To do this, they have teamed up with turtles, strapping GoPros to their shells in order to get a better look at the coral reefs and understand what's going on with them.

Over the years, the reef's population has started to decline due to pollution and global warming. WWF are hoping to put the pressure back on the Australian government to do more to protect this natural wonder.

Why is the Great Barrier Reef dying?

It's well known that the The Great Barrier Reef is in danger of dying out. Over the years, as global temperatures continue to rise, so too does the sea temperature, which is starting to have a knock-on effect on the reefs.

As corals grow, they form bands, much like you would see in trees. These bands contain chemical signatures, which have been used to identify heat-related stress to the reefs.

When the water temperature gets too hot, corals release an algae that gives them nutrients and colour - an event known as bleaching.

While corals can survive bleaching, if they continue to face stress from heat, it can cause them to die out completely. So far, there have been four recorded bleaching events, with the last one taking place just last year, which saw record high temperatures in the water surrounding the Great Barrier Reef.
