Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems. When those megafauna disappear, the result is a "trophic cascade," where every part of the ecosystem reacts to the loss. How can we stay in balance? George Monbiot suggests rewilding: putting wolves, lions and other predators back on top -- with surprising results.
It may take two to make a baby - but not necessarily two to bring it up. So what makes a parent decide to stay or go? Especially if that parent is a dad. From the California mouse mother who has to kickstart her partner's paternal instincts, to Adelie penguin parents who can't leave their eggs alone for five minutes; from cheetah mums practicing promiscuity to keep the dads on side, to flamingo parents both producing milk for their young. We see just how far these incredible parents go in order to protect and nurture as many offspring as possible through to adulthood.

They cannot tolerate sunlight; some of them are even blind. However they are one of the world's most ingenious builders: Termites. They build high-risers that are, relatively speaking, 25 times higher than the Empire State Building in New York. They are the only animals that have managed to build an air-conditioning system without electricity. Their nests are architectural masterpieces that rise up to eight meters from the ground and contain brood chambers for larvae, corridors for transportation and fungal gardens for nutrition. Termites - The Inner Sanctum takes us along a journey into another world. Visit the skillfully built termite mounds in the savannah, termite nests in the tropical rainforest with their colossal columns of termites foraging for food - and the termites that wreak terrible damage to wood-framed homes. Filmed in the US, Kenya and Borneo.

Venture into the heart of Namibia, where some parts of the landscape receive less than an inch of rain each year. Yet, despite its arid nature, the southern drylands exude a desolate beauty thanks in part to the massive sand dunes--the largest in the world--that dominate its Atlantic coastline.
