Nitrogen pollution identified as major driver of biodiversity loss in UK coastal waters

Phys · May 06, 2026 · 466 words · By Kathy Thomas

Environmental Conservation Marine Biodiversity Pollution Impact

A study by Swansea University and Project Seagrass indicates that nitrogen enrichment is a primary driver of biodiversity loss in UK coastal waters. The research suggests that current regional conservation targets may be insufficient and recommends site-specific nutrient reduction strategies.
