Surfers Against Sewage is an environmental charity founded in 1990 by surfers in Cornwall to improve water quality and protect the UK's oceans. They educate communities about conservation, organize beach cleanups that have removed over half a tonne of litter, and advocate for policies to address issues like water pollution, plastic waste, and threats to surfing areas. Some of their successes include educating over 1,000 students about ocean conservation and engaging companies like Haribo to improve packaging and reduce litter. They continue working to enhance ocean protections and gain recognition for surfing as part of UK heritage and culture.
