The African Tsetse fly carries the lethal human, sleeping sickness and the cattle equivalent, nagana. To outside observers, effective Tsetse eradication programme would seem to offer nothing but benefit-its all round. Yet conservationists argue that Africa needs the Tsetse fly to protect it's remaining wildlife and that eradicating the Tsetse from Africa's forests just opens them up to invasion by still more land-hungry settlers and their herds of cattle which destroy the vegetation to cut shamba's to grow food. Bruno Sorrentino's beautifully shot film looks at both sides of the dilemma. But then it moves the argument on to ask whether the problems caused by Kenya's population explosion don't already mean that the argument to preserve the Tsetse fly has itself become redundant
