Until the 1950s, the Waorani were able to successfully defended their area of settlement – today’s Yasuni National Park in the Ecuadorian Amazon – with the aid of spears. Then Christian missionaries entered the thick rain forest and paved the way for an oil company. Nowadays many of the tribes are estranged as some want to benefit from the short-term money the company is offering while others fight to preserve their land, culture and independence under all circumstances.
