The role of 80-million year-old rocks in American slavery — Lewis Dartnell at The Interval

When cretaceous-age rocks in the Southern US eroded over millions of years, they produced a uniquely rich, fertile soil that landowners realized was ideal for growing cash crops such as cotton. It was the soil from these rocks that slaves toiled over in the era of American slavery—and the same ground that ultimately became the epicenter of the Civil Rights Movement.

From Lewis Dartnell’s talk at The Interval, “ORIGINS: How Earth’s history shaped human history.”

About the talk

From the cultivation of the first crops to the founding of modern states, the human story is the story of environmental forces, from plate tectonics and climate change, to atmospheric circulation and ocean currents.

Professor Lewis Dartnell will dive into the planet’s deep past, where history becomes science, to explore a web of connections that underwrites our modern world, and that can help us face the challenges of the future.
