The ocean is where life first began, and where it first experimented with the mating game. All the creatures living here face the same challenge - how to find a partner in the largest and least-populated habitat on earth.

In Africa's ancient south-west corner, two extraordinary deserts sit side by side. Water is in short supply, yet these deserts are somehow full of life because the creatures that live here have turned the rules of survival on their head. This film celebrates nature's ingenuity, no matter how tough it gets.

To win the mating game here, you need to be able to stand out from the crowd. For some it's all about putting on a show, whereas others must fight for their chance of victory. And for a few creatures, working together is the key. Chimpanzees are notorious for their brutality and violence, and for most this is the simplest way to secure a mate.

Another three presenters visit people fighting to rebalance vulnerable habitats around the world. Liz Bonnin travels to California to learn about the increasingly invasive wildfires hitting the headlines. Scientists can see clear links between the fires, climate change, raised temperatures and an extended drought season. There is one crucial element that is key to a sustainable future in California: biodiversity.
