How the world is coming together to save coral reefs. Volunteer. Despite notable successes at the local level, we still have a gap to make significant impacts at the ecosystem level. Thankfully he agrees. Scientists globally are involved in much research into how we can achieve this. And we know the answer. Climate change and rising sea temperatures are the biggest threat. Plant a coral: Join our efforts to plant and restore corals in the Caribbean, Mexico, and Micronesia. Coral reefs produce a huge amount of oxygen And we kind of need O2 to survive. Peter is managing director at Lady Elliot Island, the eco resort Iâm launching into the ocean from. We may lose them all by 2050.

I dive once more off Lady Musgraveâs shores before itâs time to check out the neighbouring carbon-positive Pumpkin Island â a privately owned island that runs as an eco-retreat and, quite remarkably, manages to offset 150% of its annual carbon emissions. Your excitement will help others get involved. Weâll still have a reef, but there will be less biodiversity. Professor Peter Harrison and a team at Southern Cross University have successfully trialled larval re-seeding (that is harvesting coral eggs and sperm during the coral spawn season, growing the coral larvae in laboratory tanks, and then re-seeding it on reefs in the Philippines and on the Great Barrier Reef to re-establish breeding populations. Become an informed consumer and learn how your daily choices such as water use, recycling, seafood, vacation spots, fertilizer use, and driving times can positively (or negatively) impact the health of coral reefs. The Coral Reef Alliance (CORAL) is a non-profit, environmental NGO that is on a mission to save the worldâs coral reefs. But it too holds scars from human destruction. 10 ways to protect CORAL REEFS. âI can point to just out here, a few feet from the shore, to some of the most stunning coral youâll ever see and youâd find it hard to believe that seven or eight years ago, it looked like a desert,â Peter tells me. If climate change continues at its current rate, thereâs a real threat coral reefs will be dead within our lifetime. Following the widely reported unprecedented mass coral bleaching events of 2016 and 2017, this isnât what I expected to find on Australiaâs Great Barrier Reef. Weâll be sharing more about how we can save coral reefs together during our Earth Day webinar on April 22 nd.

Small, daily actions can help reduce coral reef loss, like reducing stormwater and fertilizer runoff or â¦ My breathing is laboured, soaking up my supply of oxygen at an unsustainable rate, as the waves pound my body. Recommendations are being made, studies conducted and funding sought in order to save coral reefs. Plastic bags, unfortunately, look like jellyfish. We work collaboratively with communities to reduce direct threats to reefs in ways that provide lasting benefits to people and wildlife. The efforts to save coral reefs cannot be ultimately successful, and they wonât be restored to their potential until the environment becomes more hospitable to their survival. How to cite this article, National Oceanic and Atmospheric Administration, Five Things You Should Know About Coral Reefs. Coral around the world has been dying at unprecedented rates, largely the result of warming ocean waters due to climate change. Tragically, since 2016, this has been the case for half of the reef â 80% of the coral along the reefâs north coast was killed off as a result of heat stress. Why we need to save the coral reefs 1. This, in part, triggered the Paris Agreement â a United Nations-sponsored agreement between nearly 200 countries to combat climate change and reduce greenhouse gas emissions. Coral reefs serve a lot of important functiâ¦ Acidification, which occurs as seawater absorbs CO2 from the atmosphere, reduces the amount of carbonate available for corals to build their skeletons, so reefs grow more slowly and become weaker. I head to Lady Musgrave, an uninhabited coral cay popular with nesting turtles. Mitigating climate change is the only long-term, sustainable solution to conserve and restore coral reefs.

Use a biodegradable sunscreen, like Aethic, which produces a triple-filter, eco-compatible sunscreen, Monitor changes: Lots of resorts and dive centres supply coral health charts you can take into the water to monitor the coralâs colour and report any possible bleaching concerning, Take nothing: Many eco-resorts have commandeered the motto âtake nothing but pictures, leave nothing but footprintsâ â listen to it, Oyster Diving referral or open-water course. I hope to see you there! And the birds are pooping. The results? When we reach the new site, I steel myself and dive in. Often, the best way to conserve a coral reef is by establishing a Marine Protected Area (MPA). MPAs define what is allowed to happen where, and can be set up to achieve a wide variety of objectives. Signs are dotted across the island, encouraging visitors to be mindful of the footprint they leave and to report anything that might impact negatively on the reef and wildlife. When Iâve regained my composure a little, I ask the skipper to take me to somewhere with shallower, calmer waters. A resilient coral reef is one that can either resist a large-scale stressful event or recover from it. A coral cay formed entirely by sedimentary debris, the island appeared above sea level some 3,500 years ago. The question is not if we can save the coral reefs, but if we choose to. Corals can recover, but the process stresses and may kill them. It has around 900 islands, more than 2,900 individual reefs, and provides a home for in excess of 1,500 species of fish. âWeâve seen some bleaching here, but itâll take time to figure out if the algae will come back or if itâs gone forever.â.

Since Peter discovered how the reef can be protected through land-based maintenance, other islands in the area have followed suit. Coral reefs are like underwater cities, inhabited by thousands of species, built up by the calcium carbonate skeletons of corals. So the turtles spend more time at the surface, trying to breathe, and thatâs when theyâre more susceptible to being hit by boats, too.â We stroll on the powdery white sand of Lady Musgrave Island, spotting turtle nesting sites tucked in the shade of the trees. Itâs clear- if destinations like the Turks and Caicos islands are to keep their pristine seas and beautiful reefs, we need to take action now. Genetics is also becoming a larger area of coral research, giving scientists hope they might one day restore reefs with more heat tolerant coral. MPAs can be set up by the government, but in many places, traditional and local leaders have established their own community management areas which they also monitor and enforce. Contact with the reef will damage the delicate coral animals, and anchoring on the reef can kill corals, so look for sandy bottom or use moorings, if available.

And it is, after all, humans that are ruining this place. The recent years of conservation have seen the turtles return to lay their eggs. The less water you use, the less runoff and wastewater that will eventually find its way back into the ocean. Weâve known for 30 years that climate change leads to the death of entire coral reef ecosystems, and yet weâve done almost nothing to save them. We know climate change is the single greatest global threat to coral reefs. It was first occupied in the 1920s when a factory producing soup from turtle flesh was built here. The next weighty punch came in the 1950s, when tourism was introduced. Killing rats could save coral reefs. Finally, stay informed and spread the word! With sea temperatures averaging 27C, the southern part of the reef is in a much safer space compared to the 35C further north. 8 Easy Ways You Can Help Coral Reefs Here are some simple, effective actions you can take to help save coral reefs and the fish, animals and plants that depend on them. Peterâs words stick with me, and I keep them in mind as I head off to see whatâs happening on the other islands on Queenslandâs Capricorn Coast.

We have to keep in mind how inspiring nature is â if we give it a hand, itâll take it. âCloser to the coast and further north, there are cities washing pollution into the ocean,â Peter continues. Water from the ocean is desalinated to reduce the amount of drinking water being imported in plastic bottles, energy comes from solar power, and waste is composted in a pit system to support the growth of more foliage. Reduce your carbon footprint "Climate change is the greatest threat to coral reef ecosystems," according to the NOAA Coral Reef Conservation Program. Coral reefs are facing a host of local stressors. Inform yourself of safer choices for coral. âWe put the forest in for the forestâs sake,â he explains from the driving seat of a buggy as we bounce over the islandâs somewhat basic roads. Not only do other animals rely on coral reefs for food and shelter, humans also rely on coral reefs because they are nurseries and homes for hundreds of fish species that we harvest. For a decade in the 1800s, the island was visited by workers mining guano (bird poo) â used as gunpowder and fertiliser â which virtually wiped the land of all vegetation, save for eight Pisonia trees.
