Neptune grass is the oldest living thing in the world. One hectare of this seagrass can absorb as much carbon dioxide as 15 hectares of rainforest. They act as the lungs of the Mediterranean Sea because of the large amounts of oxygen they produce. In 100 years, 30% of them have died out. Thanks to Posidonia, we can bathe in the stunningly turquoise waters when docking the luxury yachts. Take a deep breath of fresh sea air before splashing about and think about going out diving in a rowing boat next time.
