Voters in Greenland have backed a party which opposes a rare earth mining project. On Business Weekly, we ask what this means for the security of the global supply of rare minerals and hear why this project was so controversial. From the ice to the ocean, where the race to extract minerals is on. But environmentalists are concerned that deep sea mining could hurt the world’s oceans, even if they are being mined to help the environment in other ways. You may have heard of the term non-fungible token, but do you know what they are and how they work? We look at whether they are just another crypto craze or an amazing financial opportunity for digital artists. Plus, how to learn the art of complaining. The show is presented by Lucy Burton and produced by Matthew Davies.
