This week's programme in the series on man and science today.
For some time now rhinos have been disturbing the workers in the Tanzanian sugar plantation and ripping open the plastic water pipes to get at the water.
These incidents, and the hunting of the rhinos by helicopter, are typical of the increasing conflict between wildlife and man for land in East Africa.
The main part of this film, the second of two made by Horizon in East Africa earlier this year, concerns this struggle in the Amboseli Game Reserve in Kenya between the wild game herds and the nomadic Masai. Improved medicine is not only increasing the number of Masai themselves but also the size of their herds, and the wandering cattle feed on the vital grass-lands, leaving arid dustbowls behind them. But how do you control the preordained patterns of existence of both the game herds and these prehistoric tribes? This film follows scientists and game wardens as they try to work out a pattern of coexistence.
