Does plastic around the world really get recycled? Not at all! Only 9% of discarded plastic is recycled. Plastic pollution is threatening the marine ecosystem worldwide. More than 8 billion tons of plastic are produced by humanity, and about 8 million tons are dumped into our oceans every year, where it persists for decades. Over the next years, the amount of marine plastic waste will double if we do not act. A global issue affects our ocean, our health, and our well-being. In fact, oceans host 80% of the planet’s biodiversity, they are the largest ecosystem on Earth, and are an import source of food. Despite the fact that researchers are uncertain about the nature and extent of the risk of marine debris on ecosystems and humans, the concern about plastic persistence and their effects on the oceans has increased since the last decade. Once in the ocean, the huge amount of plastic, although widespread, affects the safety of sea transport, fisheries, tourism, recreation, and biodiversity

            Worldwide over 600 million people depend directly or indirectly on fisheries and aquaculture for their livelihoods. Fish provide essential nutrition for over 4 billion people and at least 50 percent of animal protein and essential minerals to 400 million people in the poorest countries. In addition to the pressure exerted by human activities, such as over-fishing, habitat degradation and pollution, both fisheries and ecosystems are exposed to threats related to climate change. It is known that climate change is part of Earth's geological history, but that is not all. In the last 150 years we have been observing a rapid warming of the atmosphere, intensified in the last decades and attributed to the increase in the emissions of greenhouse gases, mainly carbon dioxide from human activities.             Climate variability and change are already affecting aquatic systems physical, chemical, and biological processes. On the coastal zones for instance it is observed in
