As the Earth gets warmer, the Great Barrier Reef is facing more danger than ever. Dive in to discover what’s harming our coral reef and how you can help protect it!
Australia is a beautiful and unique country. Not only is it the home of cuddly koalas and cute kangaroos, it’s also home to some pretty interesting sea life, too! While a platypus or sharks may come to mind, it’s actually the coral on the Great Barrier Reef that needs our care and attention right now more than ever before.
The Lowdown on coral
Imagine putting on a snorkel and taking a peek under the sea. You’d see plenty of coral – a colourful living organism that attaches itself to the bottom of the ocean floor. Having coral in this type of habitat is really essential for other marine life, as it provides protection, a place to live and a much-needed rest stop for most sea creatures. Coral may look like a bunch of plants dotting the bottom of the sea, but as they use their tiny tentacles to capture prey and food to stay alive, they are in fact, classified as animals. How cool is that?
Bleached as, bro
Sadly, the coral on the Great Barrier Reef (the north-east coast of Australia) has been suffering from what is known as coral bleaching. Coral is really sensitive, and needs certain types of conditions to exist. When these conditions change, coral can get stressed, which can lead to a loss of colour or worse still, death. Usually, when the sun is too hot or the water temperature is too warm, coral can turn completely white. This is due to a plant that lives inside the coral called zooxanthellae algae, which can only survive if the temperature is just right. It’s not all bad news though, as coral can fade to white and go into stress for months at a time, but can regain its colour as soon as the water temperature drops. But, what if the water temperature keeps rising?
A Warm world
Planet Earth is heating up, and the ocean is feeling it. Warmer seas mean more bleaching, stronger cyclones, and stressed marine life. Scientists are working hard on coral restoration and seeding projects to help reefs recover, but cutting carbon emissions is still the biggest way to make a difference. It’s so important to take care of our environment so we can enjoy beautiful natural wonders like the Great Barrier Reef for many years to come!
The domino help?
When coral bleaches and dies, algae and seaweed can take over. That changes the whole ecosystem of the reef. This means fewer fish, fewer turtles and fewer different species overall. It’s a chain reaction that affects everything from tourism to ocean health. Imagine a bunch of seaweed taking over the colourful reef… Sad face! It’s time to do our part to help save the Great Barrier Reef!
What can we do to help?
Coral bleaching and the breakdown of the amazing Great Barrier Reef might feel like something too big for us to change, but everyday choices really do make a difference. Bleaching is happening more often now because long, intense marine heatwaves are putting huge pressure on the reef, and cutting pollution and greenhouse gas emissions helps reduce that stress. That’s why lowering our carbon footprint matters… it’s all about reducing the amount of carbon dioxide released by saving energy and making small changes that add up. So how can you help? Turning off electricity if you’re not using it, walking or riding to the local shops or school instead of driving, and choosing a fan over the air‑conditioning are all simple ways to help protect the environment. It’s not too late to start, and you can feel good about helping the planet!
