Will the World Come Together to End Ocean Plastic Pollution? It Depends

The global community has solved significant environment problems, such as the ozone hole, but has fallen far short on others. When it come to plastic pollution, environmental researcher Malcolm David Hudson asks, which way will the world go?

In early December 2017, the United Nations Environment Program (UNEP) in Nairobi announced a resolution on marine litter and microplastics. The move was widely welcomed as the emerging “plastic oceans” crisis has become starkly clear.

It is estimated that 8 million metric tons of plastic waste finds its way into the ocean each year, and it is notoriously difficult to remove. The impacts are increasingly apparent: great rafts of plastic are congregating in ocean gyres, blame games have broken out between neighboring countries, and marine species face poisoning from the associated toxins.

There may even be direct risks to humans, especially the 400 million or so poor people who depend critically on fish for their food. As yet, fisheries are more threatened by over-exploitation and climate change, but we are now finding plastics in our marine ecosystems and even in food such as mussels and oysters.

A Timeline, but Not Binding

Given the urgency of the problem, a more decisive global leadership is needed and so the U.N.’s announcement is certainly timely. Its resolution on marine litter and microplastics is the first genuine global attempt to tackle the problem. It aims to eliminate marine litter in the long term, urging counties to take action by 2025, to “prevent and significantly reduce marine pollution of all kinds” and “encourages” them to “prioritize policies” that “avoid marine litter and microplastics entering the marine environment.” Among other promising points, an international working group will be set up to seek legally binding options to tackle marine litter, and it is encouraging to see that almost 40 countries have signed up to the voluntary Clean Seas campaign since its launch in February 2017.

The elephant in the room here is the lack of any binding targets. Under pressure from key players like the United States, China and India, the UNEP has backed off putting in targets or binding commitments, although it was reported that the U.S. was at least engaged in the discussions. It is worth noting that China is the biggest emitter of plastic marine litter and along with the U.S. and India has a very large plastic manufacturing sector.

Alarming Parallels

There are alarming parallels with the past two decades of attempts to tackle climate change. Evidence that greenhouse gases emitted by human activities were causing more energy to be trapped in our atmosphere has been increasingly clear since the mid-1990s, but vested interests combined with the need for equitable treatment of developing countries means that progress has been painfully slow – so slow that it will now be much harder to stay within the 2C (3.6F) limit that scientists view as potentially manageable for future generations. Even now, while the evidence is clear and the impacts are painfully apparent round the world, the U.S. has backed out of the 2015 Paris agreement.

But we are capable of better. In the 1970s and 1980s, we faced another major environmental threat. Pollutants used in refrigerants (chlorofluorocarbons, or CFCs for short) were damaging the ozone layer, which acts as a protective screen from the worst of the sun’s ultraviolet rays. Alarm bells were ringing as skin cancers increased, and scientists predicted a catastrophe within decades.

That time, despite the now-familiar lobbying and stalling by industry, which argued that the science was uncertain and that more evidence was needed, the world got together. The Montreal Protocol was agreed in 1987 and since then the harmful chemicals have been phased out or managed more effectively. We have seen the ozone layer recovering toward pre-1980s levels and, in a positive unintended consequence, the phasing out of chemicals that are also potent greenhouse gases.

We humans have a mixed track record. The recovering ozone layer shows that we can, if we have the will and the leadership, get to grips with even the most wicked of environmental problems and turn things round. But, as our attempts to deal with climate change have shown, progress can be slow and getting everyone working together remains fraught with difficulty.

We should not forget that plastics have revolutionized our lives – I am typing this on a plastic keyboard, for instance, while wearing a plastic-fiber fleece, and looking through plastic lenses in my glasses. Any change will be tough and could have economic consequences.

But however important plastic seems to our lives, we depend even more on the health of the oceans for our well-being and for that of the planet. Right now, attempts to get the world together to deal with plastic waste and ocean pollution are at a crossroads; at least it’s good news we have made it this far.
