Around 640,000 tonnes of fishing gear is left in the oceans each year, this remains in the marine ecosystem for hundreds of years.
Over one million seabirds are killed by ocean pollution each year. Three hundred thousand dolphins and porpoises die each year as a result of becoming entangled in discarded fishing nets, among other items. One hundred thousand sea mammals are killed in the ocean by pollution each year.
Plastic debris can absorb toxic chemicals from ocean pollution, therefore poisoning whatever eats it. In fact, plastic pollution is one of the most serious threats to the ocean.
