We face many global problems, such as drought, flooding and climate change. All of these issues are rooted in science. It'll take politics and people and business to fix them, or for us to manage them, but none of that can happen without a solid scientific base.

In front of an audience at the Hay Festival, Adam Rutherford is joined by Steve Jones, Professor of Genetics at University College London, Marcus du Sautoy, the Simonyi Professor of the Public Understanding of Science at the University of Oxford, and science journalist, Gaia Vince, to discuss what the future holds for humanity and the planet, what we can know, what we can predict, and what is to come.

Adam Rutherford talks to Gaia Vince about the new age of man, the Anthropocene, and the impact it is having on peoples' lives, to Marcus du Sautoy about chaotic systems and when maths can and cannot predict the future, and to Steve Jones about forecasting human population growth and how we are still evolving.
