Plastic bags and balloons floating in the water look like jellyfish. Turtles often eat them and choke or starve to death because they have so much plastic in their stomachs.Seabirds eat polystyrene balls and plastic buoys, after confusing them with fish eggs and crustaceans. This makes them very sick!Baleen whales such as blue whales, humpbacks and southern right whales take big gulps of water to feed on krill that they filter through their baleen, and may accidentally swallow plastic rubbish when feeding. The plastic stays in their gut and stops them digesting their food, leading to a slow death!
