UK scientists, MPs and campaigners warn that growing microplastic contamination in agricultural soils could threaten food security. Sewage sludge applied as fertiliser is identified as a major source, carrying plastic particles from wastewater onto farmland. Researchers fear microplastics may affect soil structure, microorganisms, fertility and crop productivity. The report calls for legally binding reduction targets, stricter controls on pollution sources, better wastewater treatment and nationwide monitoring to understand the scale and long-term consequences of soil contamination across the United Kingdom.
