We throw tonnes of rubbish away and globally we’re throwing away more than ever. But what happens to it? Well, that depends on where in the world you live. Some gets recycled, some gets burned and some ends up in dumps or landfill.

British author Oliver Franklin-Wallis has written a book all about rubbish (Wasteland: The Dirty Truth About What We Throw Away, Where It Goes, and Why It Matters). He explains where some of it ends up - and why he’s hopeful about the global waste situation. The BBC’s Duc Ha tells us about the impact of imported waste and recycling on Vietnam.

Also we hear about the UN’s Global Treaty to End Plastic Pollution; the BBC’s Esme Stallard breaks down what it is and whether it’ll make a difference. Betty Osei Bonsu, 26, from the Green Africa Youth Organisation, has been attending UN summits where this treaty has been discussed. She describes what it was like and what her organisation is doing to try to reduce plastic pollution in Ghana and Uganda.
