Biodiversity in the Mediterranean Sea is threatened, in fact, more so than in any other maritime environment on planet Earth. This claim was made by scientist of the Spanish CSIC institute (Consejo Superior de Investigaciones Científicas), a governmental body in Madrid. According to a study conducted by the Spanish scientists, a combination of overfishing, habitat loss, pollution, the arrival of invasive species and the increase in temperature due to climate change, presents a serious threat to marine biodiversity in the Mar Mediterráneo. The research done by the CSIC scientists is part of a global census of marine life, consisting of an international network of researchers aiming to characterize the biodiversity of the world’s oceans, as well as its distribution and abundance, with 25 areas of study.

According to the scientists, the particular problems of our Mediterranean Sea is the fact that it is not an open ocean but a sea largely surrounded by land mass. The study highlights that the more any sea is enclosed the more it is threatened.

Let’s hope it is not too late.

  1. Biodiversity has an intrinsic value that is worth protecting regardless of its value to humans. This argument focuses on the conservation of all species, even if they are ecologically equivalent species.
    Biodiversity performs a number of ecological services for humankind that have economic, aesthetic or recreational value. This argument focuses on conserving ecologically nonequivalent species since ecologically equivalent ones are redundant in terms of services rendered.

  2. Both points of view (intrinsic and anthropocentric) need not be contradictory, as they serve the same ultimate purpose. Yet they often are considered incompatible because they stem from two very different philosophies: one which views nature as innately valuable and one that regards it as economically valuable.
    Both the intrinsic value and the anthropocentric values are presented in this page. The debate regarding the value of biodiversity and the need to protect it is still very hotly contested. The reader is left to draw their own conclusions from the arguments presented.
