Episode 3: Predators
From Caribbean coral reefs to Yellowstone's forests, serious disruptions in once-stable ecological zones are being linked to a common factor: loss of major predator species. As scientists work to understand the vital role of predators, the question remains: even if humans can co-exist with large carnivores, is it too late to bring them back?

Episode 4: Troubled Waters
Something is decimating aquatic life in the world's oceans, rivers, ponds, and streams. Now, set sail with scientists studying the rapidly increasing pollution of our waterways, and see how advanced research using plants and bacteria is being deployed to help stem the rising toxic tide.
