The three main travel agents peddling damaging short haul flights in central Bristol have been 'closed' by climate change direct action group Plane Stupid. Posters announcing the shops are 'CLOSED, FOR A TOTAL RETHINK' have appeared on the shopfronts, and one store has been closed for business more firmly by a bike lock across the front door handles. Plane Stupid have called a day of direct action against the short-sighted madness of cheap short haul flights. Aviation is the fastest growing cause of climate change.
