Here is the intro:
"The U'wa people have lived peacefully in the cloudforests of the
Colombian Andes for as long as anyone can remember. The last great
tragedy to befall these 5,000 people happened 400 years ago, when
according to oral histories, a portion of the tribe committed mass
ritual suicide rather than submit themselves to Spanish rule. Today,
the U'wa are once again talking about death as new invaders
-Occidental Petroleum ("Oxy")- move onto their land. As the project
moves forward one thing becomes very clear: Whether it is through
the pollution of the land they consider sacred, the increased violence
that the project will inevitably bring, or by their own hand, oil
exploration means the death of the U'wa."
