Half of Britain's urban beaches may be littered with man-made debris, research suggests. A study on Scotland's east coast has found that up to half of some coarse sediments at beaches like Torryburn and Ravenscraig are not naturally occurring materials such as sand or pebbles, but human-made substances like brick, concrete, glass, and industrial waste.
The researchers' findings were made possible by climate breakdown, which is causing more frequent and intense coastal storms that erode coastlines. As a result, these human-made materials have been swept up from land into the ocean and deposited on beaches. This process has created "urban beaches" where man-made debris dominates the landscape.
One example of this phenomenon is Granton beach near Edinburgh, which saw up to half of its coarse sediments made up of human-made materials. These were largely derived from industrial sites along the Firth of Forth that have been eroded by coastal storms.
The same issue has been observed in other parts of Britain, such as Crosby beach in Merseyside, where wartime waste has transformed what is now considered sand into a landscape dominated by bricks and other human-made debris. Meanwhile, researchers at the University of Glasgow have identified "Thames potatoes" – rounded-up litter that has washed up on banks opposite Canary Wharf.
Larissa Naylor, one of the study's co-authors, warned that the findings highlight the need for further research into urban coastal areas and how human activity affects ecosystems. She noted that while climate change is a major factor in this issue, it is not the only one – other factors like pollution and neglect also play a role.
The discovery has sparked calls for greater awareness about the impact of human activity on the environment. As Naylor said, "Beaches are not static landforms – they change" – and researchers say that understanding these changes is crucial to managing our coastlines in the face of an increasingly unpredictable climate.
