The Lakes with Simon Reeve S01E02 - Episode 2

The adventurer explores the impact of humans on the Lake District, discovering that the high number of visitors to Scafell Pike is damaging England's highest peak and stretching the resources of mountain rescue volunteers. He goes wild swimming in the crystal clear lake of Buttermere, before taking a look at the less-fortunate Derwent Water, one of the many lakes now clogged with invasive New Zealand pygmyweed.
