In an electrifying speech delivered at the opening of the World Leaders Summit on Climate Change in Glasgow, Sir David Attenborough gave a message of hope on behalf of the world that through action, we will witness the recovery of the natural world. But his warning of what will follow should we fail to act was also clear and stark. Sir David's speech was illustrated with stunning, cinematic pictures shown on giant screens behind him, produced by Silverback Films, the production company that has collaborated with him on many of his most celebrated natural history documentaries.
