David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe.

And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.

Rocks, dunes, sand and dust - large areas of Namibia in southwest Africa are characterized by deserts. Riverbeds full of sand meander through these inhospitable regions. Some of these only have water once every few years when enough rain has fallen in the mountains and the water rushes to the coast - but most of the time the river courses have dried up. And yet they are crucial for the survival of many living beings.
