Yanomamo describes the crisis situation in the Amazon Basin, where rainforest trees are being felled for use as commercial timber, the land cleared for ranching, and thousands of peasants from Brazil's overcrowded cities arrive in search of a better life.

The Yanomamo is the oldest Indian Tribe living in the forest. Unlike our own civilisation, which uses natural resources with little thought for the future. the Yanomamo lead a way of life in harmony with nature which, undisturbed, would survive with the forest for the next twenty thousand years and more. The Indians' existence, and that of millions of animal and plant species, is threatened by the destruction of the trees and the arrival of the incomers.

Outsiders assume that the soil is permanently rich and expect that once the trees are cleared, the land will be very productive. But after two years, no crops will grow. Why? Because the richness of the jungle is in the trees, not in the soil.

The delicate balance of nature is being systematically removed, and soon the rainforests, which are crucial to the world's eco-system, will disappear together with the Indians and the wildlife.

Is there the time or the will to save them?
