We produce more and more technology, we ask the Earth for more and more resources. But I’ll let you in on a secret: at home, in our drawers, there is a small treasure, or rather a mine made of critical raw materials and rare earths. To extract them, however, we must learn to deal with technological waste, the famous WEEE. To broaden the perspectives of all of us (including myself), I had a long chat with the legendary Luca Perri, famous astrophysicist and science popularizer loved by young and old. His live shows are literally irresistible!
Fasten your seatbelts because today, on Earth Day, THE LIFE OF TECH leads you to discover what is hidden inside your end-of-life tech devices but above all we will explain how to manage them in a more conscious way.
We speak more and more often of rare earths, of the critical raw materials that are extracted every day in different parts of the world – but above all in China – and which are used together with columbite, tantalite, cobalt and lithium to produce our tech gadgets and cars electric. Too bad that most of the things we think are totally green and sustainable often have unexpected implications: they are not very sustainable from an environmental point of view and from a human point of view (human rights are often trampled on). How to solve this so complicated (and not complex?)
To shed some light on this very thorny subject, I asked for help from the supernatural gifts of Luca Perri, an astrophysicist and top-level science popularizer; Luca manages to explain any type of topic – even complicated – making it within everyone’s reach.
If you are curious, to know all this and even a little more… I suggest you do not miss our interview with Luca Perri.
The Streets of Tech it’s also available in podcast format so you can listen to it whenever you want: in the car, on the plane, before going to sleep or while you’re working out at the gym or when you go for a walk.
In the unfortunate event that you are only interested in some of the topics of the interview, the video has been divided into chapters which correspond to a question.
