To sea turtles, plastic bags in the water can look like jellyfish, floating on the surface plastic can appear to be a tasty snack for a seagull, and to baby perch it appears more appetising than the plankton they are supposed to eat.
Over 90 million tonnes of fish were caught in 2015, according to the United Nations' Food and Agriculture Organisation. Poisoning our seas reduces the fish population and in turn this is poisoning the current fish stocks .
Given plastic degrades to pieces small enough to pass through the stomach into the flesh of fish and other animals, we are already eating some of the plastic we have thrown into the sea.
