Waste generated by human activities has now reached the deepest point in the Mediterranean: the 5,112-meter-deep Calypso Deep in the Ionian Sea. A total of 167 objects—mainly plastics, glass, metal and paper—have been identified at the bottom, of which 148 are marine debris and 19 others are of possible anthropogenic origin. These results represent one of the highest concentrations of marine litter ever detected at great depths.
