Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science, or ultimately be consigned to history. Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer. But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them for stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.
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? Part 1: The animals go head to head in a series of rounds testing different aspects, beginning in this edition with intelligence, sensory powers and physical prowess. On the search for answers, dog-lover Chris comes face to face with a pack of wolves, while feline fan Liz confronts an Arabian wild cat to discover how the relationship humans and their pets have evolved.

In this episode, Professor Brian Cox shows how Earth's basic ingredients, like the pure sulphur mined in the heart of a deadly volcano in Indonesia, have become the building blocks of life. Hidden deep in a cave in the Dominican Republic lies a magical world created by the same property of water that makes it essential to life. Clinging to a precipitous dam wall in Italy, baby mountain goats seek out Earth's chemical elements essential to their survival. In the middle of the night in a bay off Japan, Brian explains how the dazzling display of thousands of glowing squid shows how life has taken Earth's chemistry and turned it into the chemistry of life.

It may take two to make a baby - but not necessarily two to bring it up. So what makes a parent decide to stay or go? Especially if that parent is a dad. From the California mouse mother who has to kickstart her partner's paternal instincts, to Adelie penguin parents who can't leave their eggs alone for five minutes; from cheetah mums practicing promiscuity to keep the dads on side, to flamingo parents both producing milk for their young. We see just how far these incredible parents go in order to protect and nurture as many offspring as possible through to adulthood.
