Description

It was plants that first harnessed light from the sun to create a life-giving atmosphere, transforming a barren rock into the lush world we know today. In this program, geologist Iain Stewart journeys from a spectacular rain forest growing inside a cave to remote African deserts to explore the crucial role of the plant kingdom in the development of life on Earth. He also uncovers the epic battle between the dinosaurs and the planet's tallest trees, explains why plants are green and oceans are no longer purple, uses electron microscopy to show plants breathing, and provides photographic evidence of plants signaling other plants of danger - captured here on film for the first time.
