As marine life around the world embarks on epic journeys across the planet’s oceans, we discover how ocean traffic, over-fishing and noise pollution could have an impact.
In the northeast corner of Botswana, the rainy season is months away. The sausage tree offers a beguiling oasis for wildlife--from birds and insects, to much larger mammals like elephants--all reeling from the dry conditions. Then, as the rains descend, brilliant red flowers bloom and entice parrots, squirrels, and sunbirds to help with pollination. Summer allows the sausage tree to live up to its name, delivering massive, sausage-shaped fruit, a nutritious feast and a cornerstone of life in this exotic ecosystem.
Armed with the latest global scientific research, Chris Packham and Liz Bonnin battle it out to find the definitive answer to the burning question - which are best, cats or dogs?

So what is the difference between you and a rock? This seems like an easy, even stupid question. But even the smartest people on earth have no idea where to draw the line between living and dead things.
Mammals' ability to learn new tricks is the key to survival in the knife-edge world of hunters and hunted. In a TV first, a killer whale off the Falklands does something unique: it sneaks into a pool where elephant seal pups learn to swim and snatches them, saving itself the trouble of hunting in the open sea. Slow-motion cameras reveal the star-nosed mole's newly-discovered technique for smelling prey underwater: it exhales then inhales a bubble of air ten times per second. Young ibex soon learn the only way to escape a fox - run up an almost vertical cliff face - and young stoats fight mock battles, learning the skills that make them one of the world's most efficient predators.
Raising children is no easier in the air as it is on the ground, as bird parents care for, defend, and even kill their young.
