The History of the Planetary Ecosystem

Our world has led a long, sometimes tumultuous, and always complicated life. Over the last four billion years, Earth’s geology has changed radically and dramatically.

Earth, a new five-part BBC documentary narrated by naturalist Chris Packham, tells the story of this change by looking at significant moments in the planet’s history - from the dramatic moment when nearly all life on Earth was wiped out, to the end of the dinosaurs and the rise of humanity.

In this episode, Chris explains why he was drawn to working on the series, explores issues of human-driven climate change and biodiversity loss, and explains the perhaps counterintuitive role that romance plays in science.
