In this special edition for World Oceans Day, we spotlight the urgent, haunting work of Mandy Barker, the award-winning British photographic artist using sea-salvaged fashion waste to expose the truth about plastic pollution. Her cyanotype series "Photographs of British Algae: Cyanotype Imperfections" reimagines the work of 19th-century botanist Anna Atkins, replacing seaweed with clothing scraps collected from 121 beaches around the UK. The result is both poetic and jarring, earning praise from none other than Sir David Attenborough, who supports Barker's work for its power to inspire real change.
