Hannah Ritchie discusses her new book 'Not the end of the world' with Prof Charles Godfray. We are bombarded by doomsday headlines that tell us the soil won't be able to support crops, fish will vanish from our oceans, that we should reconsider having children. But in this talk, data scientist Hannah Ritchie, author of Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet will discuss with Professor Sir Charles Godfray, Director of the Oxford Martin School, that if we zoom out, a very different picture emerges. They will discuss how the data shows we've made so much progress on these problems, and so fast, that we could be on track to achieve true sustainability for the first time in history and we can build a better future for everyone.
