Like many people i have lived my whole life feeling guilty and deeply depressed about the terrible state of the world -so much so that i have often felt like there was no point in doing anything about it. this book changes everything because it puts all that bad news (which we are constantly inundated with) into fact-based context. the data that is presented in this fascinating and entertaining book challenges just about everything i believed about the world we live in without in any way minimising the changes that still need to be made
