Windermere turning green due to high touristnumbers, researchers say | BBC News

High visitor numbers are turning one of Britain's most scenic lakes green, researchers say.

A report funded by the UK space agency suggests alink between peak tourist periods and algal blooming at Windermere in the Lake District.

Algal blooming is caused by warm temperatures andnutrients, and can make the water green and toxic.

Campaigners are linking the blooms to discharges ofsewage, which although mostly treated, are nutrient-rich.
