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 Africa's savanna, a swarm of 1.5 billion red-billed queleas are caught on camera, the largest flock of birds ever depicted.
