From the Vellmari association, San Félix is mapping Posidonia, with initiatives such as an App that advises boats where not to anchor. Together with other organisations such as the Aquae Foundation, it has been warning for decades about the decline of the plant, which has lost 40 percent of its surface area in the Mediterranean due to human activity, even though, if left undisturbed, it can live for thousands of years. Aquae has its own learning zone, and Vellmari organises the Dive Camps in Mallorca and Formentera, where young people can spend a few days getting to know the seabed through diving and snorkelling. Posidonia is such a familiar landscape for the inhabitants of Ibiza and Formentera that it has always been a part of everyday life. Its leaves and stems are the stuff of utensils and ornaments, Elisa Pomar y varias de sus piezas, inspiradas en el mundo marino. // Elisa Pomar and several of her marine-inspired pieces.
