This week, Nico chats to Nacho Dean - an environmentalist, an adventurer and an Earth ambassador. They discuss the lessons learnt from his Earth Wide Walk adventure as well as his Nemo Expedition, about which he has recently published a book. They discuss the importance of coming together as a global community to fight climate challenges and the systems change which this requires.
