10 million tonnes of litter end up in the oceans every year. That is one garbage truck per minute, 400 kilos per second. Millions of marine animals die every year because of marine litter, including sea birds, seals, whales, dolphins and turtles. In some areas, micro plastics already outnumber plankton by six to one. And the prospects for the future look grim: by 2050, there could be more plastic than fish in the seas and 99% of seabirds could have ingested plastic.
