Up in the Air
Dr Tara Shine takes a deep breath and marvels at something we all take for granted: oxygen. She demonstrates how Earth produces a never-ending supply of this gas - the raw material for all complex life - and investigates what else is in the air that we breathe.
One critical component is carbon dioxide, a greenhouse gas that’s causing a dangerous rise in atmospheric warming. Tara will look at the carbon footprint of a loaf of bread and how hydrogen might be the answer for heating and transport. From developing exciting new technologies, to protecting wetlands and forests, the solutions are everywhere. Our ideas and ingenuity can create a better, cleaner and more sustainable future.
