Steve Brusatte traces the remarkable evolution of birds from their dinosaur ancestors, showing how they gradually developed defining traits like feathers, wings, keen senses, and flight. He explores how birds survived the asteroid impact 66 million years ago—the only dinosaurs to do so—and then rapidly diversified into the thousands of species found around the world today. Along the way, he introduces striking extinct birds, from towering predators to giant seabirds, while also highlighting the intelligence, adaptability, and surprising behaviors of modern species, from tool-using crows to parrots that mimic speech.

A raw look at the environmental damage caused by humans and the resilience of the plants that survive it. Joey Santore explores how invasive species, habitat loss, and modern development have disrupted ecosystems, while emphasizing the vital role plants play in sustaining life. Despite the damage, he highlights practical ways individuals can support native ecology and biodiversity, showing how small actions can contribute to restoring a fragile planet.
