Every second of every day, an estimated 256 kilogrammes (kg) of plastic is dumped in oceans globally — about 22,000 tonnes per day.
Discarded plastic nets ensnare mammals and birds, fish ingest micro-fragments, and the shoreline and seabed is increasingly littered with rubbish.
Alarmed by these statistics, a Belgian living in Barcelona identified a business opportunity.
He created Sea2See, a start-up that recycles discarded plastic fishing nets to manufacture sunglasses and optical frames.
