Pollution from the “huge” pig and poultry farming sectors is harming rivers, the wider landscape and nature, a report from the Wildlife Trusts warns. HotspotsThe situation is particularly acute in the “hotspots” where poultry and pig production are concentrated, the report warns. Conservationists are calling for the government and industry to support farmers to shift to a less polluting and more integrated pig and poultry system to clean up rivers and help meet legally binding environmental targets. In Wales, nearly 56 per cent of the total poultry flock is in Powys, and in Northern Ireland, two-thirds of pig holdings are in just two council areas – Armagh City, Banbridge and Craigavon, and Mid Ulster. While environmental regulations are in place for pig and poultry housing across the UK, the report warns the majority of breeding sows in England fall outside environmental permitting rules, along with significant proportions of pig populations across the UK.
