According to a 2020 study published in the scientific journal "Nature Communications", as of late 2018, there were an estimated 31-85 trillion microscopic plastic debris floating near the surface waters of the Mediterranean Sea, ranging in size from 0.5 microns to 5 millimeters. It's important to note that this quantity does not include larger-sized plastic materials (macroplastics) or those found on beaches, the seafloor, or within organisms. The presence of such extensive microplastic debris raises significant concerns about potential negative impacts on marine life and ecosystems in the Mediterranean.
