16-year-old climate change warrior Greta Thunberg has spoken to the Pope, parliaments and MEPs about species extinction, deforestation and ocean pollution. She is not alone in her action against global warming. For two decades David Attenborough has warned of the dangers. He now says that scientific evidence proves that if we do not take dramatic action within the next decade, we face irreversible damage to the natural world and the collapse of our societies. Since 15 April, Extinction Rebellion protesters have been disrupting cities globally in 18 countries, calling on governments to introduce stricter climate change measures. They said, ‘Prosecution for criminal damage allows us to take this strategy into the courts, providing an opportunity to tell them that, without an urgent and radical change, the consequences for humanity and life on earth are likely to be catastrophic.’ See
