Meet Posidonia oceanica

Hello there! May I introduce you to Posidonia? And all the guys are thinking "hell yeah you can!" Posidonia's surname is oceanica, and its really a genus name rather than a surname.. yes you've guessed by now! Posidonia oceanica is not a person but a plant, a flowering plant in fact, that makes its home in the Mediterranean sea.

Posidonia oceanica is already your friend, only you probably don't even know it.  Posidonia provides shelter and breeding grounds for many of the delicious fish, bivalves, cephalopods, and crustaceans that so often find their way onto your dinner plate.  Your leisure is provided for when Posidonia attenuates currents and waves that would otherwise erode away the beach on which you may choose to sunbathe in summer or stroll along during the winter.  Posidonia oceanica breathes life into the underwater world by releasing large volumes of oxygen, supporting all kinds of existence both in the sea and, indirectly, on land.

As one of the receivers of all of these benefits, you may want to be aware of the current threats to Posidonia's wellbeing.  Members of your same species, Homo sapiens, are jeopardising Posidonia's home by spilling chemicals and excess nutrients into the sea, discharging brine from desalination plants, introducing invasive species, dredging and trawling.  Posidonia oceanica's address has always been 'No 1, "All Over", The Mediterranean Sea'; there really is no other place for her to seek shelter until the danger is over.  It is far time we started to appreciate the many advantages of our relationship with Posidonia.  Where would we be without her I hear you ask? Who knows, lets not wait to find out!!
