Should we mine the deep ocean? - The Climate Question Podcast, BBC World Service

In the global race for critical minerals - could the seabed provide solutions? Or should we leave these metal-rich environments undisturbed? Click here to subscribe to our channel 👉🏽 https://bbc.in/3VyyriM Governments and mining companies around the world are on the hunt for the metals we need for the green tech transition. And there’s growing interest in an unlikely source – potato-shaped nodules that are found kilometres below the surface of our oceans! These contain high levels of elements like cobalt, nickel, manganese and copper. Supporters of deep-sea mining say that harvesting polymetallic nodules might be less damaging to the environment than mining on land. But many scientists support a moratorium; they say industrial activity on the seabed could damage the biodiversity of a part of our planet that is currently not fully understood. The BBC’s Climate and Science Reporter Georgina Rannard has been following the deep-sea mining story for five years. She chats to Hosts Graihagh Jackson and Jordan Dunbar. 01.15 The weird and wonderful creatures in the deep ocean 05.37 Polymetallic nodules and why mining companies want them 08.10 How do you do deep-sea mining? 09.35 Potential risks to wildlife 13.10 The “dark oxygen” controversy 15.20 Nickel mining on land in Indonesia 19.30 Do we need deep-sea mining? 20.56 Alternative sources including the Moon!
