"A hectare of this ancient, delicate plant can soak up 15 times more carbon dioxide every year than a similar sized piece of the Amazon rainforest.
But this global treasure is now under extreme pressure from tourists, from development and ironically from climate change.
Posidonia oceanica is found all over the Mediterranean but the area between Mallorca and Formentera is of special interest, having been designated a world heritage site by Unesco over 20 years ago.
Here you'll find around 55,000 hectares of the plant, which helps prevent coastal erosion, acts as a nursery for fish, but also plays a globally significant role in soaking up CO2."
