Coral Reefs and Climate Change

Ocean Conservation in action, 2023

Coral reefs around the world are now facing challenges that put their very existence at risk. Rising sea temperatures, ocean acidification, and destructive practices have taken their toll worldwide, jeopardising the pillars of our oceans ecosystems.

1. What is a Coral Reef?

A coral reef is like Mother Nature’s bustling underwater city, but it’s not a plant—it’s a vibrant living community!

Picture a bustling neighbourhood where corals, which are actually tiny animals called polyps, are the architects.They build intricate limestone homes, forming colourful underwater gardens. 

These coral condos provide shelter to a kaleidoscope of marine creatures. It’s like a non-stop block party, where everyone relies on each other for food, protection, and a place to call home. 

Coral reefs are the lifeblood of our oceans, and they remind us of the incredible interconnectedness of our planet’s ecosystems.

2. Threats to Coral Reefs

Coral reefs are facing a mounting onslaught of threats, primarily driven by climate change. 

One of the most insidious threats is ocean acidification, a consequence of rising carbon dioxide levels in the atmosphere. As our oceans absorb more CO2, they become more acidic, which weakens the calcium carbonate structures that corals depend on for their growth and survival. 

Simultaneously, rising sea levels driven by the melting polar ice caps are reducing the amount of sunlight reaching coral reefs, hindering photosynthesis in the symbiotic algae that corals rely on for nutrients. 

These climate-related challenges are causing widespread coral bleaching and die-offs, imperilling the ecosystems that are not only vital for marine biodiversity but also for the millions of people who depend on them for their livelihoods. Urgent action is essential to mitigate these threats and protect the future of coral reefs.

3. The Great Barrier Reef

The largest living structure on Earth.

The Great Barrier Reef spans 2300km (1429miles), making it visible from space.  Yet, this natural wonder has been under threat due to the increasing impacts of climate change and human activity. But hope is on the horizon, thanks to the Great Barrier Reef Foundation’s Coral Restoration Project.

As we all know, the Great Barrier Reef is a sprawling underwater city teeming with life, home to 25% of all known marine species. Home to a dazzling array of corals, fish, and other marine creatures that form the largest living structure on Earth.

4. Saving our oceans from Climate Change

Great Barrier Reef Foundation offers hope for reefs globally.

One key strategy Great Barrier Reef Foundation is implementing involves high-tech nurseries, where scientists meticulously cultivate coral fragments before transplanting them onto deteriorating reefs, successfully providing a second chance at life.

In addition, coral IVF enables corals to reproduce more efficiently, creating increasingly resilient strains built to withstand the challenges of a changing climate. 

Beyond the lab coats and cutting-edge innovations of 3D mapping and coral DNA sequencing, The Foundation engages local communities, businesses and governments to foster a culture of environmental stewardship. The ripple effects of positive change extend far beyond the reef itself, serving as a reminder that the Great Barrier Reef is not just Australia’s treasure; it’s a global heritage.

These projects are an invitation to the world to join hands and take part in an epic journey of conservation and restoration. One dedicated to bringing the largest living structure on Earth back from the brink of extinction.

5. How you can help

Everyone has the power to help bring our reefs back from the brink of extinction.

Consider:

  • Conserving water to reduce runoff pollution
  • Practising responsible diving and snorkelling by avoiding touching or damaging corals.
  • Choosing sustainable seafood options to protect reef-dependent fish using this sustainable seafood guide.
  • Reducing your carbon footprint in all the ways you’re already aware of
  • Choosing sustainable seafood options to protect reef-dependent fish using this sustainable seafood guide.
  • Raising awareness about coral reef conservation and advocating for policies that combat climate change and ocean acidification.
  • Supporting organisations such as Great Barrier Reef Foundation through donations, fundraising or volunteer work; we are actively partnering with organisations such as The Foundation to create awareness for ocean conservation volunteering and internship opportunities.

Together, we can breathe new life into the sea and ensure that the Great Barrier Reef remains a symbol of hope and inspiration for all oceans.

We are proud to stand with Great Barrier Reef Foundation during the most critical decade in history.
