Climate Change: Don't sideline plastic problem, nations urged

Scientists are warning politicians immersed in climate change policy not to forget that the world is also in the midst of a plastic waste crisis.

They fear that so much energy is being expended on emissions policy that tackling plastic pollution will be sidelined.
A paper from the Zoological Society of London (ZSL) and Bangor University says plastic pollution and climate change are not separate.

It says the issues are actually intertwined - and each makes the other worse.

Manufacturing plastic items adds to greenhouse gas emissions, while extreme weather such as floods and typhoons associated with a heating planet will disperse and worsen plastic pollution in the sea.

The researchers highlight that marine species and ecosystems, such as coral reefs, are taking a double hit from both problems.

Reefs and other vulnerable habitats are also suffering from the seas heating, from ocean acidification, pollution from farms and industry, dredging, development, tourism and over-fishing.
And in addition, sea ice is a major trap for microplastics, which will be released into the ocean as the ice melts due to warming.

The researchers want politicians to address all these issues – and not to allow climate change to take all the policy “bandwidth”.
Professor Heather Koldewey from ZSL said: “Climate change is undoubtedly one of the most critical global threats of our time. Plastic pollution is also having a global impact; from the top of Mount Everest to the deepest parts of our ocean.

“Both are having a detrimental effect on ocean biodiversity; with climate change heating ocean temperatures and bleaching coral reefs, to plastic damaging habitats and causing fatalities among marine species.

“The compounding impact of both crises just exacerbates the problem. It’s not a case of debating which issue is most important, it’s recognising that the two crises are interconnected and require joint solutions.”
