I have seen the film "Willing to Sacrifice"
This film vividly tells the story of the Bishnoi religious community, specifically Nihal Chand, who died at the hands of poachers in 1996. Colorful visuals and gripping narrative document the history of this remarkable sect which believes in protecting wildlife and was founded in the deserts of Rajastan 500 years ago .

The Bishnois are a community of nature worshippers in the state of Rajasthan, India. They also have a sizeable presence in the neighbouring states of Uttar Pradesh, Madhya Pradesh, Maharashtra, Gujarat,Haryana, Punjab and Delhi.
The sect was founded by Guru Jambheshwar (b. 1451) after a drought in the Marwar region of India. He had laid down 29 principles to be followed by the sect. Bish means 20 and noi means 9; thus, Bishnoi translates as Twenty-niners [1]. Further, the Guru directed the worship of lord Vishnu (Bishnu), thus the sect is called Vishnoi or Bishnoi. Killing animals and the felling of trees were banned. One of his 29 principles states "JEEV DAYA PALNI, RUNKH LIL0 NAHI GHAVE" which means to protect trees and animals, thus trees and animals are considered to be sacred by the Bishnois.
Bishnois are strong lovers of wild animals. It is because of their protection that in Bishnoi-dominated areas, deer and antelope (such as blue bulls, black bucks, chinkaras and chowsinghas) are seen grazing peacefully in their fields despite the fact that the State of Rajasthan where the Bishnois mainly live, faces severe water shortages.
In recent years, the Bishnoi community has launched strong protests against the killing of black bucks by Salman Khan, a Bollywood film star and Mansur Ali Khan of Pataudi, a former Indian cricketer. Noted chartered accountant and social activist Mangilal Bishnoi led the demonstration against actor Salman Khan in Mumbai. In New Delhi, Mr. Sharvan Bishnoi(sharan) given the notice to Menaka Gandhi, Salman Khan was convicted on the evidence of Bishnoi witnesses.
