Sewage having 'alarming' impact on underwater forests along UK coast
New research found that sewage and agricultural pollution in rivers is having an 'alarming' impact on marine life in underwater forests along the UK coast, with excessive nutrients causing a significant decline in small invertebrates. The study examined 16 sites along the British coast and found that higher concentrations of nitrogen and phosphorus were associated with reductions in animal abundance and species richness.
Sewage and agricultural pollution in UK rivers is harming marine life in underwater forests. Researchers studied 16 sites along the British coast and found excessive nutrients caused a decline in small invertebrates like crabs, shrimps, and snails. The team discovered that higher nitrogen concentrations were linked to a 90% decrease in life per unit of available habitat area. Increased phosphorus levels also had a devastating negative effect on life within lagoon environments. Algae-smothered seagrass meadows in the Thames estuary and the Firth of Forth were among the worst affected areas. The research highlights the need for integrated thinking to protect the marine environment by addressing land-based pollution.
