Greenpeace activists target the South Downs National Park Authority meeting with a ‘Not For Shale’ roadshow, on the launch of a new investigation into fracking in Sussex. The activists put 'Not For Shale' signs by the historic Cowdray Ruins close to the South Downs National Park Authority building in Midhurst where the meeting is taking place. Lord Cowdray supports Greenpeace and the anti-fracking protests.
