The star of this episode of ''Planet Earth'' is a very special plant: grass, because it can survive snow, fire, water, heat and cold, and it's also a precious food source for many animals! We will travel across the globe: from Mongolia to Africa, from the Arctic tundra to the Asian rain forests, and even from Tibet to North America!
Our journey begins in Mongolia, as we see many Mongolian gazelles migrating and giving birth to their off springs, and an eagle with her nest hidden in the high grass, then a fire bursts, but after this sad scene we see that grass can re-appear from under the ashes. Soon we see two of the greatest animal migrations ever: red billed queleas (6 millions of them) and a massive wildebeest herd!
We then move to the arctic tundra, where a giant flock of geese returns to their nesting sites, and some Arctic foxes try, even succeeding, to steal and kill goose chicks. In the meanwhile a massive caribou herd migrates towards warmer climates, and is also stalked by a couple of wolves that kills a baby caribou separated from his mother. Soon it's the turn of the North American plains, where a massive herd of bisons stops for relaxing and fighting.
We take a brief visit to the flourishing South African welts, with ostriches and antelopes that stroll around peacefully. While in the frozen Tibetan plains we see wild donkeys fighting and a grey fox that kills a pica, the closest relative of the rabbit. And also some birds that live in the burrows.
In Asia there is a really tall grass called ''elephant grass'' where elephants use to walk, and it's also used as a nest for pygmy boars; and a bird, called lesser florican, jumps up and down in the hopeless search of a mate!
Our journey ends in Africa, with elephants that stop for drink, and then, a chilling scene: a group of lions that at night kills and then devours young elephants! Then we see awesome footage of the flooded plains in the Okavango delta, a mecca for all animals that search tasty food and fresh water.
It's a great episode, and all goes to: 1) George Fenton's outstanding music 2) David Attenborough's narration 3) The stunning shots of our planet's grasslands and the animals that inhabit them!
