Being an "outdoorsy" person teaches you a lot along the way. In the mountains, we see the effects of climate change clearly before our eyes. Matthias' guest this time is the far-sighted entrepreneur, avid athlete, speedflyer and film maker Malcolm Wood. With documentaries like The Last Galciers or A Plastic Planet – which David Attenborough called the most important film of our time – the mountain advocate in the UN world environment programme has made it his mission to share his experiences with the world. Enjoy this heartfelt, inspiring and profound conversation.
