In this first episode of Earth Unscrewed, a new podcast powered by Virgin, presenters Dr. Helen Scales and Seyi Rhodes get into the topic of cars. With over a billion vehicles on the world’s roads, air-pollution levels are reaching deadly highs. Helen and Seyi explore some breakthroughs that are gaining traction, and that might help ‘un-screw’ the planet. Delve into London’s sewers in search of a surprising clean fuel, and meet the innovators working hard to make costly and polluting cars a thing of the past, by racing clean ones around city centres.
