Lake Windermere in Cumbria could become 'ecologically dead' within the next few years due to the amount of sewage pumped into the water, a campaigner has warned.

Matt Staniek, a conservationist, wildlife advocate, and regular visitor to the lake, launched an online petition calling for an end to sewage dumping in the water.

Windermere could become “ecologically dead” because of the amount of sewage being pumped into its waters, campaigners have warned.

Pictures show algal blooms across the surface of the lake. Campaigners say there is also evidence of dead fish and invertebrates, indicating the waters are not healthy.
