Somehow, human beings have found a way to exist alongside Mother Nature’s most breath-taking creations. What makes these Natural Wonders so extreme? What are the challenges to human survival within them? And what helps and what hinders us in that struggle?

Answer (and stunning photography) are found with PBS Distribution’s Earth’s Natural Wonders: Season 2: Life at the Extremes. This program, presented in partnership with the BBC, takes viewers to parts of the natural world that nature has carved out on such a scale that they beggar belief.

Vast mountain ranges, impenetrable rainforests and dazzling tropical islands—places where nature is visible at its most primal, most powerful, and most extraordinarily beautiful. For human beings, survival within these wonders can pose extraordinary challenges. Yet in even the most extreme and remote parts of our planet people do survive.
