Will deep-sea mining save us from climate change?

Billions of unassuming rocks on the seafloor could help humanity save itself from the ravages of climate change. These polymetallic nodules contain cobalt and other metals which we need for batteries, electric cars and photovoltaic systems. But harvesting them might destroy deep-sea ecosystems. Special thanks to GEOMAR Helmholtz Centre for Ocean Research Kiel We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.
