On the eve of Earth Day, over a thousand Christians from diverse denominations came together in London for a climate protest against new fossil fuel exploration, particularly in the North Sea, and to call for a transition to a sustainable, just and fossil-free world. The event was a part of ‘The Big One’, a four-day protest organised by Extinction Rebellion and attended by Operation Noah, Christian Aid, Tearfund, Christian Climate Action, CAFOD, A Rocha UK and Green Christian.
