Extinction Rebellion protesters wave flags as London Marathon runners pass through Parliament Square on April 23, 2023, in London, England. XR and like-minded groups are inviting members of the public to the Unite to Survive event at 'The Big One'. This is a four-day action running from the 21st to the 24th of April where people will gather throughout Westminster and at the Houses of Parliament hoping to put pressure on politicians to act on climate change.
