The sombre statement was the first public event for the Extinction Rebellion North Devon group, which has joined the thousands around the world who say they are taking a stand for the planet. Dressed in black, with green armbands of mourning, more than 100 people took part in the silent procession from Barnstaple Square and up through the High Street. Many bore pictures of animals that have already gone extinct and at the command of a mournful bell, they paused periodically in the High Street to hold a silent vigil before continuing. Extinction Rebellion sees an increasing number of people convinced it is faced with a global emergency and a very real threat to survival if climate change is not slowed within a decade.
