The Serengeti Rules
The Serengeti Rules is a 2018 American documentary film directed by Nicolas Brown, and based on the book by Sean B. Carroll. The film explores the discoveries of five pioneering scientists—Tony Sinclair, Mary E. Power, Bob Paine, John Terborgh, and Jim Estes—whose decades of research laid the groundwork for modern ecology and offer hope that environmentalists today may be able to “upgrade” damaged ecosystems by understanding the rules that govern them.
