Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems.

George Monbiot suggests rewilding: putting wolves, lions and other predators back on top -- with surprising results.
Chris Packham aims to raise enough money to plant 100,000 trees across Britain, by asking viewers to contribute to The Woodland Trust.

Australia, a land cast adrift at the time of the dinosaurs. Isolated for millions of years, the weird and wonderful animals marooned here are like nowhere else on Earth. In its jungles a cassowary - one of the most dangerous birds in the world – stands six feet tall. Inland, kangaroos and wombats brave snowstorms and gum tree forests are filled with never-before-seen predators. In its red desert heart, reptiles drink through their skin and huge flocks of wild budgerigars swirl in search of water. On secret islands Tasmanian devils roam and offshore, thousands of sharks gather for a rare event.
