“Destroy the lot of them.”   This man is on a mission to kick down stone stacks, which are a common sight along hiking trails up and down the UK - but why?    Stuart Cox wants to highlight the damage they can do to the environment... by kicking them over.   He’s spreading his message after a recent video he filmed of himself kicking down the stacks in the Peak District in Derbyshire, England, was watched more than a million times on social media.   Tap the link in @BBCNews’s bio to read why the National Trust agrees with him.   #Derbyshire #PeakDistrict #BBCNews
