Sea cucumbers are overlooked ecosystem engineers that keep marine environments functioning. Known as the “earthworms of the sea,” they feed on sediment, removing waste and releasing cleaner, oxygenated sand, helping prevent the seafloor from becoming oxygen-deprived. In coral reefs, they reduce harmful bacteria and support nutrient cycles, sustaining entire ecosystems. Despite their simple appearance, they have extraordinary abilities—regenerating organs and potentially living for decades or more. Threatened by overfishing and environmental pressures, these quiet recyclers are essential to keeping the ocean healthy and balanced.

Who are we - Healthy Seas

Healthy Seas is a foundation committed to marine conservation and removing marine litter, especially fishing nets, to foster healthier seas and repurpose waste into innovative products. Within our comprehensive approach to ocean conservation, an integral component involves educational outreach.

In our commitment to education, we actively engage children of various ages through captivating presentations and hands-on activities focused on marine conservation and the impact of marine litter. Additionally, we provide an immersive virtual reality experience, allowing young minds to explore as divers the underwater world and understand the importance of preserving the seas. Beyond education, our pillars encompass cleanups and prevention. In collaboration with volunteer divers and fishermen, we have successfully removed over 991 tons of waste globally. Our reach spans from the US to Korea, involving 150 partners and 550 dedicated volunteers. www.healthyseas.org
