If you think the Earth takes millions of years to change, it’s time to think again! In the second of two episodes we reveal how changes in geology affect life and how one lifeform in particular – humans - is now affecting geology. We also look how Earth is permanently altered by extraterrestrial forces: the sun causes our atmosphere to leak gas into outer space while Earth picks up 60 tonnes of cosmic dust every day. Every morning you’re waking up on a completely different planet.
