A fish with a yellow head and blue body swims through dark water, its mouth open around a red plastic object, while a translucent plastic bag floats above it; the fish turns and swims away, revealing a torn, red, plastic-like body, as another fish with a yellow beak and red head swims past, followed by a scene of a crab entangled in a plastic bag and a lobster holding a piece of red plastic, ending with an octopus whose body is formed by a white plastic bag, all set against a dark, murky underwater backdrop.
