During the documentary, Bonnin watched a shearwater chick's stomach being pumped to remove pieces of plastic.

She also accompanied a team of biologists who examined a dead seal pup, later determining a plastic chord wrapped round its neck as the cause of death.

"This is just utterly heartbreaking and devastating," one viewer posted on Twitter. "How have we allowed this happen to our planet?"
