About us

Gili Reef Guardians is a youth-led environmental initiative based on Gili Air Island, Indonesia, dedicated to protecting our coral reefs and regenerating the ocean’s ecosystems.

Our Mission

We are on a mission to restore coral reefs, clean our oceans, and protect our island home. Through innovative technology and community education, we aim to bring life back beneath the surface.

Preserving Whales: Essential Guardians of Our Oceans and Key Protectors of Marine Ecosystems for a Sustainable Future

At Blue Hope, we are dedicated to the protection and preservation of whales and their ocean habitats. Whales play a vital role in maintaining the balance of marine ecosystems, and their survival is directly linked to the health of our planet. 

Through research, conservation efforts, and advocacy, we strive to safeguard these magnificent creatures from extinction.

Our History

The Story Behind

What began as a simple dream from two 12-year-olds — to save the reef around their home — has grown into a powerful community movement. Today, local youth, dive centers, and eco organizations work hand in hand to restore coral reefs, plant trees, and build a more sustainable future for the Gilis.

Youth-Led Island Regeneration

More than reef restoration — this is a movement to protect Gili Air from the impacts of rising over-tourism. Our local youth champions are taking action to restore balance between people and nature:

  • Planting 1,000 trees every year to bring back shade, oxygen, and wildlife.
  • Restoring coral reefs to heal the ocean and protect marine life.
  • Educating local schools and running creative community projects to reduce plastic pollution. 
Gili Reef Guardians

Over the past three decades, the world has lost nearly half of its coral reefs due to global warming, pollution, and overfishing.

When the coral dies, so does marine life — fish, anemones, crustaceans, and countless other species lose their homes.

Coral reefs are the rainforests of the ocean, but today they are bleaching — turning ghostly white as warmer waters create unsafe conditions for them to survive. Once the corals bleach, they overheat, weaken, and eventually die, leaving behind lifeless seascapes where vibrant ecosystems once thrived. 

Help Our Cause

Every bit of support helps us protect what we love. 💚

Your donations go directly toward building new Biorocks, cleaning the ocean, and educating island youth.

Corals are not just beautiful — they are essential. They produce up to half of the Earth’s oxygen, protect coastlines from erosion, and sustain marine biodiversity. Without corals, our planet and all its life are in danger.

Please consider donating — every contribution makes a difference.
