Posidonia oceanica meadows, those dark patches of seagrass that run along our coast, are ancient. Amongst the oldest living organisms in the world, these seagrass meadows measure time in thousands of years.
Some meadows have been growing since before our ancestors first walked out of Africa. They have been around as civilizations have risen and fallen, kings and queens have come and gone, battles have been fought, trading routes spread.
Dubbed the lungs of the Mediterranean, the meadows are a globally important carbon sink—they absorb at least 15 times the amount of CO2 as tropical rainforests while also producing oxygen. They act as a refuge, breeding ground, and nursery for thousands of creatures. But, because of human interference, they are fast disappearing. We may have already lost 50 percent. Now they’re ours to save.

Our first campaign begins with the belief that if people know just how precious Posidonia meadows are; how they serve to protect coastal ecosystems and communities and work to lessen the impacts of the climate emergency, and how their disappearance is directly connected to making us more vulnerable to the extremities of rising temperatures, wildfires and floods; this will inspire collective action to protect them.
Greece and its neighbours are on the frontline of the climate crisis. The Mediterranean region is warming 20% faster than the global average, putting pressure on already strained ecosystems, unstable economies and vulnerable societies.
With the longest coastline in the Mediterranean, Greece has the opportunity to take the lead in protecting this irreplaceable ecosystem and making our communities more resilient.

Posidonia Challenge:
It is not a race but we are running out of time
This October we are planning an awe-inspiring 200-kilometre, non-stop relay swim that will connect the Posidonia meadows of the Argosaronic and bring communities together to better understand the importance of this habitat and the need to protect it.
This extraordinary event will unite celebrated Greek athletes who will showcase their endurance and commitment to the cause. They will work together, swimming without stopping for two days and two nights. As they take on this challenge, the athletes will highlight the beauty and global importance of the Posidonia meadows.
The relay is also a call to action for us all, serving as a powerful symbol of unity and determination, demonstrating that collective action is what we need to preserve our natural heritage and to rise to the challenge of the unfolding climate crisis.
