Explores the grasses which are present all over the world. Grass sustains huge numbers of creatures the world over, particularly in the African grasslands, where huge numbers of savannah animals have made their homes.
Visits the world's deepest valley: the Kali Gandaki river in the Himalayas. Its temperatures range from those of the tropics in its lower reaches to that of the poles higher up. It therefore shows how creatures become adapted to living in certain environments.

Describes the inhospitable habitats of snow and ice. Mount Rainier in America is an example of such a place: there is no vegetation, therefore no herbivores and thus no carnivores. However, beneath its frosty surface, algae grow and some insects, such as ladybirds visit the slopes. Africa’s mountains are permanently snow-covered, and beneath peaks such as Kilimanjaro and Mount Kenya, there are communities of plants and animals.

Begins in northern Norway, 500 kilometres north of the Arctic Circle. Here, there is only just enough light for the pine trees to survive, but it is extremely cold during the winter. Pine cone seeds provide one of the few foods available at this time of year, and large herbivores such as the moose must also rely on their fat reserves.

Ascends a kapok in the South American tropical rainforest to observe "the greatest proliferation of life that you can find anywhere on the surface of the Earth. There are two main causes for this: warmth and wetness. As this climate is constant, there are no seasons, so trees vary greatly in their flowering cycles.

Details coastal environments and the effect of tides, of which the highest can be found in the Bay of Fundy in North America. In places, erosion is causing the land to retreat, while in others — such as the tropics — the expansion of mangroves causes it to advance.

Once life arrived in the Galapagos, it exploded into unique and spectacular forms. David Attenborough investigates the driving forces behind such evolutionary innovations. We learn that life must be able to adapt quickly in these ever-changing volcanic landscapes. It has resulted in species found nowhere else in the world, such as giant whale sharks and marine iguanas that can spit sea-salt from their noses, dandelion seeds that grow into tree-sized plants and spiders that can blend perfectly into the darkness. Adaptation has been the key to survival in these islands so far, but the story of life in the Galapagos doesn’t end here. The catalyst that triggers these explosions of life remains in place.
Once a mountain kingdom of ancient palaces and emperors, Korea in the 21st century is largely known for its modern cities and decades of conflict. Tensions between North and South may be what defines it to outsiders but beyond the battle scars there is another side to Korea. In the south are large pockets of untouched wilderness where extraordinary animals flourish and Koreans continue to practice age-old traditions in tandem with the seasons and with nature. It is in these connections, rather than in division, that we see the true Korea. At the southernmost tip of the peninsular we follow a pod of bottlenose dolphins through the volcanic islands of Jeju. They click at each other as they encounter a human in their midst, but the dolphins know this diver well - they have shared the ocean with the Haenyeo, or sea women, for thousands of years. We travel onwards to the isolated island of Marado, where three generations of sea women are preparing for a dive. Today is the start of the conch season, and they work hard whatever the weather to maximise their catch. In the grounds of an ancient palace on the mainland, a raccoon dog family takes advantage of a rare event. Just once every five years, hundreds of cicadas emerge from below ground providing an easy feast for the raccoon dogs who voraciously fill their bellies. Those that escape their jaws make for the safety of the trees, where they metamorphosise into their flying form. On the mud flats of Suncheon Bay we find a habitat that is neither land nor sea. Only recently has the ecological value of mudflats been recognised. A staggering 50 per cent of the earth's oxygen is produced by phytoplankton - microscopic algae that are found here in great abundance. That is why the mudflats are known locally as the lungs of the earth. Plankton is far from the only life here - the mud of the bay is rich in nutrients and supports one of the most diverse ecosystems on the peninsula. We follow the story of a young mudskipper who has emerged for his first mating season. His journey to find love is paved with obstacles.

For 10,000 years or more, humans created new plant varieties for food by trial and error and a touch of serendipity. Then 150 years ago, a new era began. Pioneer botanists unlocked the patterns found in different types of plants and opened the door to a new branch of science - plant genetics. They discovered what controlled the random colours of snapdragon petals and the strange colours found in wild maize. This was vital information. Some botanists even gave their lives to protect their collection of seeds. American wheat farmer Norman Borlaug was awarded the Nobel peace prize after he bred a new strain of wheat that lifted millions of people around the world out of starvation. Today, botanists believe advances in plant genetics hold the key to feeding the world's growing population.
David Attenborough narrates this documentary about the giant squid, a creature of legend and myth which even in the 21st century, has rarely been seen in it's natural environment. But now, an international team of scientists think they have finally found their lair, one thousand metres down, off the coast of Japan. This is the culmination of decades of research. The team deploys underwater robots and state of the art submersible vessels for a world first - to find and film the impossible.
