This week's programme in the series on Man and Science Today.

What happens when an industrial giant invades a primitive community? The very ground is the home of the spirits and ancestors, and when an international mining company suddenly decides to dig it up it is as though a bulldozer were being driven through heaven.
This is what has been happening in New Guinea, an island just emerging from the Stone Age, where even steel axes, bush knives and clothes are only recent innovations. The disturbing effect that these changes are having on the primitive tribesmen is one of the tragedies of the modern world. In some cases where anthropologists working there have made their voices heard the worst effects of the clash of culture have been avoided. Even though, in New Guinea, changes have almost gone too far, what has been learnt there could be a model for social change in every other part of the world.
