Plastic food and drink packaging dominates world's coastal litter

The Prevalence of Plastic Litter

Plastic food wrappers, bottles, lids, and caps are by far the most common items of litter found on the world’s shorelines, a study has found. Researchers looked at data from more than 5,300 surveys of coastal litter to produce the first global analysis of its kind.

The Global Extent of the Problem

The information collected spanned 94 countries, and the team was able to extrapolate from that data to include estimates for another 18 countries. Food and drink-related plastics turned up in coastal litter in 93% of those places. No other form of litter was as prevalent.

Regional Variations in Litter

There were, however, some regional variations. Plastic bags, for example, were consistently prevalent in Asia. The study also noted that a ban on plastic bags did not necessarily mean a country had less of such waste – poor policy enforcement or other countries exporting their waste was suggested as a reason for this.

The Impact of Plastic Pollution

Efforts to establish an international treaty to tackle plastic pollution are in turmoil. The chair of the treaty talks stepped down in October after allegations of behind-the-scenes pressure from the UN’s environment programme, which is overseeing the talks. It also emerged this month that the programme’s largest donor, Norway, was reviewing its funding for the body.

Solutions to Address Plastic Pollution

Richard Thompson, the founder of the University of Plymouth’s international marine litter research unit, said policymakers could address plastic pollution by ensuring plastics were only used for essential purposes, and that people could increasingly opt for refillable food and drink containers. Tamara Galloway, a professor of ecotoxicology at the University of Exeter, noted that current economic models tended to treat many forms of plastic as disposable, and suggested reframing it as ‘plastic-lost-value’ to guide policymakers in their efforts to mitigate it.
