After watching this film, I felt I had to do some research on things I didn't know well, and this is what I found:
"Ecocide is committing any unlawful or detrimental act that one is well-aware will cause severe, irreversible long-term damage to the environment. Ecocide has a negative human impact on the environment by causing mass destruction to our delicate ecosystems that are imperative to sustain all types of life on Earth".
The main character of this film, José, is a local community healer in the Colombian jungle, who embarks on his last journey after the apparition of his dead son, who'd been killed by one of the criminal gangs who claim this land and flagrantly exhaust its resources. José is heavily distressed by the number of ceremonies he holds for the dead, the drowned; and many of his tribe people disappeared and have never been found. José's journey is a quiet protest against these horrible killings of his people and his earth.
The movie is hypnotic, and is mostly sung rather than spoken. We observe both the wild beauty of the jungle and its violent irreversible destruction.
Educational, poetic, gives a lot of food for thought.
