We look at the ways in which plants have adapted to survive in the harshest climates on Earth. Whether in the driest, hottest deserts or the coldest Arctic wastes, plants have come up with some ingenious ways of surviving, including eating animals and actually caring for their offspring.
On the other side of the world under the crystal clear blue waters of the Pacific Ocean lies one of the most enchanting places on the planet. Over ten thousand miles away on the north eastern coast of Australia lies the Great Barrier Reef, one of the natural wonders of our world. It provides shelter to some hidden wildlife sanctuaries that contain some magical marine creatures. Iolo Williams dives deep beneath the surface of the coral sea to discover what state this natural wonder is in. He travels from the extreme swells of the northern part of the reef right down to the cooler pristine corals of the south. He discovers how healthy the Great Barrier Reef really is in some of its key locations to see and find out if there are real signs of hope the reef can survive the threat of global warming.

Watch as birds solve puzzles and challenge our basic notions of intelligence. Call somebody a “bird brain,” and you’re not delivering them a compliment. But as NOVA shows, birds turn out to have advanced problem-solving skills that we usually assume are unique to humans. Watch astonishing tests of avian aptitude: parrots that can plan for the future, jackdaws that can “read” human faces, and crows that can solve multi-step puzzles with tools like pebbles, sticks, and hooks. Could these just be clever tricks based on instinct or triggered by subtle cues from their human handlers? To rule out any doubts, NOVA puts feathered Einsteins through their paces and reveals skills that even three- or four-year-old children have a hard time mastering—such as putting off one reward now to get a bigger one later. From this revolution in thinking about our feathered friends, the conclusion seems irresistible that bird brains see the world in ways that aren’t so different from our own.
