We're sad to say it's the last in the series of David Attenborough's six part series: What are we going to do without Africa of a Wednesday eve? This week's episode is entitled The Future and sees Attenborough asking what tomorrow will bring for the great continent. He experiences the realities of rhino poaching when he meets Elvis in Kenya, examines the challenges elephants face with a growing human population taking over their turf and discovers that some Maasi warriors have taken up the business of 'lion guarding'. Powerful stuff.
