“Ever wonder where plastic ends up? I have a story I’d like to share.” This week on The Europeans, the Irish journalist Naomi O’Leary describes what happened when she visited a paradise island in a remote corner of the Caribbean, only to find the entire Western world had got there first: plastic, plastic and yet more plastic. We talk about what Naomi found and what Europe can do to stop it. And since we had her here we thought we might as well quiz her about her podcast The Irish Passport, your one-stop shop for all things Irish. In Zagreb, Daniel Martinović is on the line to discuss the success of Dugine Obitelji (Rainbow Families), Croatia’s first children’s picture book showing kids with LGBT parents. Plus: the Netherlands keeps its gas underground; a London embassy keeps Julian Assange off the net; and a tale of redemption for an amateur sculptor in Madeira.
