Balloons and balloon fragments are the deadliest kinds of marine pollution for seabirds, killing almost one in five birds that ingest the soft plastic, according to a new study published in the journal Scientific Reports.
The research, conducted by scientists at the University of Tasmania, examined the cause of death of 1,733 seabirds, 32 percent of which had ingested marine debris. Hard plastics — items like LEGO bricks or straws — accounted for 92 percent of all items ingested. Soft plastics — including packaging, rubber, foam, rope, and balloon fragments — accounted for just over 5 percent of items ingested but were responsible for 42 percent of seabird deaths. Balloon fragments, specifically, composed just 2 percent of ingested plastic, yet the scientists found that if a bird ingests a balloon or balloon fragment, it is 32 times more likely to die than if it ingests a hard-plastic fragment.
