Humanity is under threat - from storms that seem to get ever fiercer, earthquakes that seem ever more deadly, and killer viruses that are engulfing the globe. Some scientists think it's time for us to fight back. Can we - should we -hack the planet?
Saiful investigates how to generate energy without destroying the planet in the process. Saiful begins his lecture by being plunged into darkness.
