Description

This week, we take a break from nuclear power to talk about larger systems: those of Planet Earth. Professor Andy Knoll, renowned Harvard geologist and author of A Brief History of Earth, reveals how life itself has shaped Earth's chemistry, climate, and geology. From the oxygenation of Earth's atmosphere to the potential colonization of Mars, we explore the constant and delicate dance between life and the planet.
