We all know that plastic isn't great for our planet. But how much do scientists really know about how it's affecting nature - including our own species? Tori and Khalil try to get their noodles around 'nurdles', the tiny plastic pellets that are used to manufacture all manner of everyday objects, discovering that millions are ending up in our oceans, with unknown long-term consequences. Plus, join Natural History Museum researcher Alex Bond on Lord Howe Island, a remote paradise in the Tasman sea and mecca for nesting seabirds, where chicks are falling prey to an ominous new disease: plasticosis. You'll find out: -What caused Sri Lanka's worst maritime disaster? -How much do we know about how microplastics affect human health? -Can we get to a global agreement on ending plastic pollution?
