Party Balloons Are Killing Seabirds

The deadliest ocean garbage for seabirds is balloons, not plastic straws.

In a recent survey of over 1,700 dead seabirds, more than a quarter of the deaths were linked to eating plastic. Four in 10 of those deaths were caused by soft debris such as balloons (which are often made of plastic), even though it made up only 5 percent of the inedible trash in the birds’ stomachs.

Seabirds frequently snap up floating litter because it looks like food; once swallowed, it can obstruct birds’ guts and cause them to starve to death. If a seabird swallows a balloon, it’s 32 times more likely to die than if it had gulped down a piece of hard plastic, researchers reported in a new study.

“Among the birds we studied, the leading cause of death was blockage of the gastrointestinal tract, followed by infections or other complications caused by gastrointestinal obstructions,” lead study author Lauren Roman, a doctoral candidate with the Institute for Marine and Antarctic Studies at the University of Tasmania in Australia, said in a statement.

With an estimated 280,000 tons (250,000 tonnes) of floating marine debris worldwide, about half of all seabird species are thought to ingest plastic on a daily basis, the study authors reported. Birds are especially likely to swallow dangerous balloons because they closely resemble squid, according to the study.

The findings were published online March 1 in the journal Scientific Reports.

As reported in another study, 90% of seabirds now have plastic in their stomachs. Unless we drastically reduce the flow of plastic entering the ocean, by 2050, 99% of seabirds will have plastic in them.
