Our oceans are swirling concoctions of waste that scientists have for years reported is fed by an influx of pollution from both the land and the sea.
But working out what rubbish winds up in the Great Pacific Garbage Patch in the North Pacific, where it comes from, and who is responsible is an ongoing challenge. Now a new study further implicates the global fishing industry in the mix.
This waste category includes items like oyster spacers, eel traps, and lobster and fish tags, as well as plastic floats and buoys.When the authors used computer models to simulate how their samples ended up in the patch, they found that a plastic fragment was 10 times more likely to originate from fishing activities than land-based ones.
Of all 232 plastic objects analyzed by researchers clues about their origins, roughly two-thirds were made in either Japan or China. Yet harder plastics over 5 centimeters in size can sometimes still contain brand or company names, and a few letters or characters can possibly reveal their origin.
