- Description
- Chris Packham tells the miraculous story of how plant life turned the Earth from a barren rock into a vibrant green world - a 4.5-billion year-saga of extraordinary highs and lows that almost wiped out all life on the planet. The Earth began as a water world without land masses. Then, a giant asteroid bombardment triggered its plate tectonics, leading to huge fungi, soil and giant swamp forests. But the early plants locked so much carbon dioxide that global temperatures suddenly plunged.
