This week, Brian Cox and Robin Ince wonder if the world would be better off without spending an undue amount of time and energy trying to get giant pandas to mate and instead concentrated on saving species which let's face it, are a lot less cute but probably more important for the planet. Should we make a distinction between the organisms we want to save as opposed to those we need to save? The science and politics of biodiversity and conservation, explored and explained (sort of) with the help of Sandy Knapp, Simon Watt and comedian Sara Pascoe. Producer: Rami Tzabar.
