 Hello and welcome to Tech Life, the programme about the technology making a difference to your life. I'm Chris Vallance and today we hear from the music legend Peter Gabriel. He's endorsed a competition to find a way of decoding animal communications using artificial intelligence and then talk back to them. Microplastics in our seas and drinking water, it's a real problem. We hear from two teenage students in Texas who found an innovative way to get rid of the stuff.
