The secret life of cats.

Worshiped as a symbol of life in ancient Egypt, and coveted by sea captains and farmers for centuries, the cat is one of the most beloved animal in history. Through the ages, it was the cat's extraordinary ability to hunt and kill rodents that endeared it to humans.

Today, cats are adored for their beauty and unique personalities. Nevertheless, the soul of a killer still lurks inside every kitty. In the time it takes to watch this film, house cats in the United States will catch as many as 100,000 small mammals and more than 30,000 birds.

From the county parks of Florida to the outback of Australia, domestic cats and their feral cousins are stalking some creatures to the brink of extinction. What is your cat doing when it slips out of the house? You'll learn more about your pet than you might want to know.

Planet Earth - Ocean deep.

It begins with a whale shark used as a shield by a shoal of bait fish to protect themselves from yellowfin tuna. Also shown is an oceanic whitetip shark trailing rainbow runners. Meanwhile, a 500-strong school of dolphins head for the Azores, where they work together to feast on scad mackerel.

Down in the ocean's furthest reaches, some creatures defy classification. On the sea floor, scavengers such as the spider crab bide their time, awaiting carrion from above. The volcanic mountain chain at the bottom of the Atlantic Ocean also sustains life through the bacteria that surround its sulphide vents. There are thought to be around 30,000 undersea volcanoes, some of them taller than Mount Everest. Their sheer cliffs provide anchorage for several corals and sponges. Nearer the surface, the currents that surround these seamounts force nutrients up from below and thus marine life around them is abundant.

Off the Mexican coast, a large group of sailfish encircle another shoal of bait fish. The hunters change colour as a message of their intentions, since an attack could also be fatal to others of their number. The last sequence depicts the largest animal on Earth: the blue whale, of which 300,000 once roamed the world's oceans. Now fewer than 3% remain. Planet Earth Diaries shows the search in the Bahamas for oceanic whitetip sharks.

Life goes to extraordinary lengths to survive this immense realm. A 30 tonne whale shark gorges on a school of fish and the unique overhead heli-gimbal camera reveals common dolphins rocketing at more than 30km an hour.

Descending into the abyss, deep sea octopus fly with wings and vampire squid use bioluminescence to create an extraordinary colour display. The first ever time-lapse footage taken from 2,000m down captures eels, crabs and giant isopods eating a carcass, completely consuming it within three hours.

Life After People.

What would happen to planet earth if the human race were to suddenly disappear forever? Would ecosystems thrive? What remnants of our industrialized world would survive? What would crumble fastest?

Abandoned skyscrapers would, after hundreds of years, become "vertical ecosystems" complete with birds, rodents and even plant life. One small animal might be responsible for bringing down the Hoover Dam hydroelectric plant. Swelled rivers, crumbling bridges and buildings, grizzly bears in California and herds of buffalo returning to the Great Western Plains: In a world without humans, these would be the visual hallmarks. Our cars would shrivel to piles of dust, our house pets would be overtaken by flourishing wildlife and most of the records of our human story�books, photos, records�would fade quickly, leaving little evidence that we ever existed.

So what would happen to the Earth if humans ceased to exist? Would all the remnants of mankind eventually disappear from our planet? How long would it take? Would endangered species thrive or would extinctions continue at an advanced pace?
