Salamis, Greece – Three divers’ heads bobbed in the sea. Then, two white balloons surfaced. Attached to them, recovered from a depth of 16 fathoms (29 metres, 96 feet), was the brown tangle of a discarded plastic fishing net.
The underwater cleanup, barely 1.5km (1 mile) offshore the island of Salamis and 40km (24 miles) from Athens, was a tiny contribution to growing efforts to rid the Mediterranean Sea of plastic waste.
