Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

Comets pose one of the greatest threats to life on Earth - a threat that can only be countered if we find out more about them. In 2005, in an audacious bid to do just that, NASA scientists launched a space probe to collide with a comet in the emptiness of deep space.

On the edge of the Namibian desert, cattle farmers are looking for new land to graze their animals. The lions, who occupied these previously wild spaces, are hunted by herd guards, or even slaughtered when they attack cows. Will and Lianne Steenkamp lived for two years in a territory occupied by a 17-year-old lioness - a "queen" -, her two daughters and their five lion cubs. This film traces the process of empowering the young: after learning to hunt alone, they will have to leave the family pack and find young females to reproduce. A necessity all the greater as their species seems threatened.

Four top predators are compared, each champion in a type of environment, with key adaptations. On the ground, the cheetah outruns prey (approached in masterly stealth) and enemies. In the air, the peregrine falcon is a flight and diving machine. In sweet water, the Nile crocodile survives since the Dino age, without natural enemies, with several amazing metabolism stunts. Lurking under water, it snaps blindly at migrating wildebeest, then waits underground. In the oceans, the equally ancient shark, notably the great white, migrates seasonally to find abundant prey, such as young seals around South Africa.
