Turquoise sea at Cornish beauty spot turns BROWN in latest case of raw sewage being pumped into the water with South West Water blaming 'climate change'

St Agnes Beach in Cornwall is well-known among locals and tourists alike for its beautiful scenery, charming village and great surfing conditions. But the usually-turquoise water was turned completely brown on Sunday morning after Cornwall's water company, South West Water, appeared to have allowed raw sewage to be discharged into the ocean. Video footage online shows a huge mass of dark brown sewage in the water, right on the coastline, which slowly mingles with the pale blue sea alongside it. One social media user shared the photo with the caption 'Speechless'.
