A BBC wildlife film crew has documented the tragic fate of a group of seabirds living on Lord Howe Island, 600 km off the coast of Australia, who are starving to death because their stomachs are so full of plastic pollution there's no room for food.
The birds will eat just about anything they find, traditionally squid and small fish. But with the abundance of plastic in the ocean, they scoop it up as well, and bring it back to the nest to feed their chicks on it.
When the chicks emerge from their burrows with their stomachs full of undigested plastic, they have insufficient nutrition to give them the strength to set out to sea and forage for themselves.
In the documentary, called "Plastics Watch," marine biologists captured hundreds of chicks and attempted to flush the plastic from their systems to give them a fighting chance.
