Collapse at a global scale In his book: Collapse: How Societies Choose to Fail or succeed in 2005. Jared Diamond, he reviews the causes of historical and pre-historical incidences of societal collapse. The book answered too the question: How societies can take so many bad decisions about her society? And J. Diamond writes about four categories to explain societal collapse: 1. Not anticipating the problem 2. The problem arrived but the group don’t perceive him 3. The group perceived the problem but they fail to resolve the problem 4. The group will try to resolve the problem without success Why I created a topic about this book? Because do you think it’s not too late to save our societies? Indeed, J. Diamond speaks about specific population (like Vikings, Malthus in Africa, easter island, Anasazis)…to exemple about his theory But today, if you look each of categories from J. Diamond you can find an exemple very tragic for our population and at the global scale! 1: We could think about progressive disappearance of bees because of GMO, Asian giant hornet, toxic mushroom. And without bees, no pollination. 2. This is clearly the global warming! Policies and population have taken lot of years to admit the relationship between the global warming and the human activities. 3. The third is everywhere! Conflict of interest, corruption, we could speak about Monsanto and GMO with the dependence of many farmer. 4. The pollution of ocean with plastic for to many decades… Well, the book is fantastic and same if the human have incredible capacity to adapt and to innovate; I’m really pessimistic for the future…
