Could coral reefs disappear in our lifetime?

Act now to protect these underwater rainforests

Coral reefs are the vibrant heartbeat of our oceans, nurturing over 25% of all marine species. Yet these vital ecosystems face severe threats from climate change and human activities that have already destroyed half of all coral reefs globally.

Unless we take immediate action, experts warn that coral reefs could vanish completely within the next 30 years - a devastating loss of biodiversity and natural wonder in our lifetime.

But there is hope. We've partnered with GaiaOne, a coral restoration organization, to launch the Heartfeldt Coral Nursery in Bira, Indonesia. This groundbreaking project will cultivate and transplant new coral colonies to revive local reef habitats.

Coral nurseries serve as safe spaces for corals to grow and develop before being transplanted onto degraded or damaged reefs as part of restoration efforts.

Heartfeldt Coral Nursery

The Heartfeldt Coral Nursery wants to bring back the beautiful coral reefs in Bira, Indonesia. We work together with GaiaOne, an organization that restores coral reefs. Thanks to our generous donors, we have already funded over 500 tiny coral pieces in our nursery. Now we are planting these baby corals onto the reefs to make them healthy again.

You can still help us grow even more baby corals. By adopting a new coral piece, you support our nursery and help us plant more corals in the future. This way, we can restore more of the reefs in Bira.

Check out our certificate from our local partner, GaiaOne.

The Value of Coral Reefs

Coral reefs are some of the most biologically diverse and economically valuable ecosystems on our planet.


Coral reefs cover <1% of the Earth's surface but are home to 25% of all marine fish species.


Coral reefs reduce wave energy by 97% before hitting the shore.


More than half of all new cancer drug research focuses on marine organisms.


Well-managed reefs produce 5-10 tons of fish/km2 per year.


70 million trips are supported by coral reefs annually.

Climate change and human activity have destroyed 50% of coral reefs already.

Threats to Coral Reefs

Many scientists now believe the very existence of coral reefs may be in jeopardy unless we intensify our efforts to protect them. (Frieler et al, 2013)


Increased carbon dioxide in oceans alters pH levels, which weakens corals, making it harder for them to build their homes and survive in changing conditions.


When stressed (high temperatures, pollution, changes in water chemistry), corals lose their colorful algae, leaving them weak and susceptible to harm, making it tough for them to recover.


Toxins from human activities, like chemicals and trash, flow into the ocean, harming coral and disrupting their delicate balance.


Boats, fishing gear, and other human actions can break or harm coral, making it difficult for them to grow and thrive in their homes.


Your generous contribution to the project deserves recognition.

We've got A's for your Q's

What is a coral nursery?

A coral nursery is crucial for restoring coral reefs. It's a safe space where baby coral fragments grow stronger. When mature, the coral fragments get transplanted back into the local reef. These robust corals fortify the reef's health and resilience, playing a crucial role in its restoration. The techniques used and the coral grown in this nursery are deliberately chosen to enhance the biodiversity of the coral reefs.

Who will be doing the job?

Our local partner, GaiaOne, will manage our coral nursery and monitor the growth of coral fragments to ensure a supportive environment for their safe development.

GaiaOne Restoration, a social enterprise based in Bira, Indonesia, has been chosen as our partner for several reasons, including their holistic approach to coral restoration. While coral planting is a significant part of their work (having already planted 14,147 corals and counting 💪), they are also engaged in other essential activities such as trash cleanups and educational programs like awareness campaigns and coral planting courses, crucial for effective coral restoration.

In what time can you see the results of this project?

Answered by GaiaOne

Short-term impacts may be visible as early as 4 months from the planting day when our coral team transplants mature corals into the reef. The next milestone is seen at 2 years if the planted coral survives changing currents, temperature changes, diseases, and natural predators. The final milestone occurs within the 5 to 10-year timeline, during which the coral has the opportunity to grow and become a new ecosystem fostering biodiversity. Success at this stage is measured by the health and number of other species supported by the existence of the coral colony.

How often will the corals be maintained?

Answered by GaiaOne
The team goes out three times a week to the Tevana House Reef and typically maintains each nursery site/area once a week.

Can I also donate in someone’s name as a gift?

Yes! If you are searching for the perfect eco-friendly present, look no further! You can gift a coral to someone by choosing the ‘Dedicate my donation in honor or in memory of someone’ option on our donation page.

I have donated but I haven't received project updates. What can I do?

First and foremost, thank you for your support! It's great that you're keen to stay informed about the project's progress. We use Donorbox to share regular updates about the project with our donors who have subscribed to them. If you haven't received any updates, please don't hesitate to contact us at and we will be sure to look into the problem.

Are locals involved in the work?

Answered by GaiaOne
Absolutely! Our project manager and coral diver are Indonesian, especially Sul, who is from Bira. We also operate two community nurseries where we collaborate with locals to restore a specific area of the reef and ensure its maintenance when the team is unavailable. Additionally, we engage with local communities to organize events in schools, aiming to educate the next generation and create awareness about marine conservation.  

How is the raised money allocated?

From the raised $3500, our partner GaiaOne will receive $2500 for establishing the Heartfeldt Coral Nursery with 500 coral fragments. The remaining funds will cover our campaign's advertisement and production expenses, including salaries and fees.  

I’ve already donated, what will happen now?

Firstly, thank you for your donation! 💙
Once we reach our funding goal, we will transfer the allocated amount for the coral nursery to our local partner, GaiaOne. They will then place the coral fragments in the nurseries, where they will grow stronger and larger under monitored conditions. When ready, the GaiaOne team will replant them into existing coral reefs to grow in their natural habitats. Throughout this process, the corals will be closely monitored and maintained, involving underwater "gardening" techniques to encourage growth.

We will keep you updated every step of the way via email and through our social media channels, so tune in.
