As wild swimming becomes evermore popular, a list of wild swimming spots in the UK is expected to include Lake Windermere, in the Lake District.
Unfortunately, Lake Windermere is turning green according to a new study.
Sky News reported:
The Save Windermere campaign group, which helped organise the study, said it showed a "direct correlation" between the number of visitors and algal blooms.
"With a clear link between human activity and algal growth, action is imperative," said Matt Staniek, founder of Save Windermere.
"Save Windermere is calling for complete removal of all sewage from Windermere."
Good luck with that.
