Forty volunteer divers carried out a clean up off Playa de Cambriles, where there are important extentions of posidonia.
This plant, also known as Neptune grass or Mediterranean tapeweed, grows in underwater meadows and is the best indicator of the ‘health’ of the seawater, so much so it is considered the ‘lungs of the sea.’
However, this species is found only in the Mediterranean Sea and is in decline, occupying now only an area of about 3% of the whole Mediterranean basin.
In just the one day that the clean up lasted, volunteers managed to remove 200 kilos of plastic and other rubbish.
The Manager of Escuela Buceo de Calahonda, who organised the clean up, Emilio Ortiz, pointed out that it is difficult to quantify the amount of plastic because so much of it is made up of very small pieces. But even so, they filled 30 sacks of the rubbish recovered during their dives.
Ninety percent of the rubbish collected was plastic,” explained Emilio, who went on to point out that nowadays there are only two posidonia meadows left on the whole of the Costa Tropical: one off Playa Cambriles (Castell de Ferro) and the other off Playa de Lance (Rubite).
The main danger to these subaquatic meadows are bottom trawlers, which although are forbidden from getting close to the coast where the meadows are sometimes stray in by error or by design.
Every year volunteers carry out at least three clean-up operations, especially after summer, which is when most human activity occurs and consequently when most rubbish accumulation takes place.
