David Attenborough, nature and climate change documentary producer. Andrew Montford, writer for reaction.life: “Tragedy porn” is now a standard green propaganda technique. First of all you need a victim. Animals – preferably fluffy ones, and preferably with large eyes – are ideal, but people will do at a pinch. Then you have to film them in the process of dying or otherwise suffering. A presenter or scientist needs to be on hand to describe the events, preferably choking away their tears. Then you blame global warming.
