Knepp is a beacon of hope for England’s wildlife. When Isabella and her husband inherited the estate to farm, they recognised how sick the land was. But a groundbreaking radical experiment has been nothing short of transformative. Now it’s a place where mussel-diving pigs, storks and butterflies find sanctuary, and where thriving flora and a vast array of animals have taken back the land. This is a charming, hopeful and necessary story of ecological regeneration.

It's death on an unimaginable scale, when a majority of Earth's species quickly die out. It's called "mass extinction," and it's happened at least five times before. Cataclysms, such as supervolcanoes or asteroids, are thought to cause these events, but some experts believe a manmade mass extinction could be next. Is our planet in trouble? And if so, is there anything we can do to stop the next catastrophic annihilation? Experts are traveling the world, performing groundbreaking scientific detective work to answer these very questions.

Diseases that were largely eradicated in the United States a generation ago—whooping cough, measles, mumps—are returning, in part because nervous parents are skipping their children's shots. NOVA's "Vaccines—Calling the Shots" takes viewers around the world to track epidemics, explore the science behind vaccinations, hear from parents wrestling with vaccine-related questions, and shed light on the risks of opting out.

Blue Whales: Return of the Giants 3D takes viewers on a journey of a lifetime to explore the world of the magnificent blue whale, a species rebounding from the brink of extinction. Following two scientific expeditions—one to find a missing population of blues off the exotic Seychelles Islands, the other to chronicle whale families in Mexico’s stunning Gulf of California—the film is an inspirational story that transforms our understanding of the largest animal ever to have lived.

Planetary scientist Carolyn Porco explains what it takes to look for life beyond Earth, and what conditions are required for life to exist. Porco argues that Saturn’s moon Enceladus—with its plumes of water vapor spewing into space, confirmed organic materials, and evidence of hydrothermal vents at the bottom of its liquid ocean—is the most promising place to look. Could Enceladus be the key to proving once and for all that life is not unique to Earth? What would it mean—both scientifically and spiritually—if we found evidence of a true second genesis right here in our own galactic back yard?

In the 1970s, Satish Bhaskar became a turtle walker: He walked nearly the entire coastline of India and the spectacular Andaman and Nicobar Islands in search of sea turtles.
