SCIENTISTS at a Scottish university have highlighted the dangers of marine pollution in a report that found almost three quarters of seabird species in the north-eastern Atlantic had ingested plastic.
The team, from North Highland College UHI’s Environmental Research Institute – part of the University of the Highland and Islands – and the RSPB Centre for Conservation Science, say a co-ordinated approach is needed to gain a better understanding of the issue.
In their paper, published in the journal Environmental Pollution, the authors collated data from all known studies reporting instances of plastic ingestion and nest incorporation in seabirds around northern Europe, Scandinavia, Russia, Greenland, Svalbard, the Faroes and Iceland.
Dr Nina O’Hanlon, a seabird ecologist at the Thurso-based institute, who worked on the project, said: “Marine plastic pollution is an increasing and global environmental issue which poses a major threat to marine biodiversity.
“The production of plastic continues to rise with millions of tons entering the oceans each year. Seabirds can ingest plastic, become entangled in it or incorporate it into their nests, causing impacts which may have negative consequences on reproduction and survival.”
Dr Alex Bond, a senior conservation scientist with the RSPB, said: “Plastic never breaks down, it only breaks up into smaller fragments which remain in the environment and, as its density varies, it can be found throughout the water column, increasing the number of species which come into contact with it.”
O’Hanlon added: “In the north-eastern Atlantic Ocean there has been little effort to better understand how marine plastic affects different seabird species over time and regionally. We believe it’s vital to have a multi-jurisdictional, co-ordinated and collaborative effort to gain a more comprehensive and current understanding of this important issue.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
