Planet Earth

A global tour examining the behaviors of animals and revealing the effects of climate change on their environments.

Although merely 3% of water on earth, fresh water plays an important part in the planets weather and erosion. It is immensely important for all non-marine wildlife, which drinks fresh water and swims, procreates, hunts in it. Its concentrations, such as rivers, lakes and swamps, abound in aquatic and other species, often adapted to wet life.

Despite the lack of rain, deserts are the most varied of our ecosystems. In fact, about thirty percent of the earths land surface is covered in desert. Explore the unique conditions present in deserts as well as the survival mechanisms developed by the animals that inhabit them.

This episode deals with savanna, steppe, tundra, prairie, and looks at the importance and resilience of grasses in such treeless ecosystems. Their vast expanses contain the largest concentration of animal life. Over Africas savanna, a swarm of 1.5 billion red-billed queleas are caught on camera, the largest flock of birds ever depicted.

A look at the shallow seas of the earth, from coral reefs to kelp forests and beyond.

An exploration of the deepest, darkest realms of the ocean, spanning countless species to a depth of 2,000 meters.
