Mark Maslin, a Professor of Earth System Science at University College London, has made it his career to study climate change and has authored hundreds of academic papers and multiple books on the topic. But now, the renowned climate scientist has taken a rather different approach with his new book, How To Save Our Planet, where he breaks down in the most no-nonsense way what we each ought to do – not just to protect Earth, but for a whole host of other reasons, from economic savings to our own health. We recently had the opportunity to speak to Professor Maslin about his latest work and the inspiration behind it, why he remains incredibly optimistic about the future and so much more.
