The correct option is Bishnois.
Explanation
Certain communities in India have integrated environmental conservation into their religious and cultural practices. In Rajasthan, the protection of specific wildlife species is a core tenet of the Bishnoi sect.
Detailed Analysis
- Bishnois: The Bishnoi community follows 29 principles (Bish means 20, Noi means 9) laid down by Guru Jambheshwar in the 15th century. These tenets strictly prohibit the killing of animals and the cutting of green trees. They are particularly known for their aggressive protection of Blackbucks, Nilgai, and Peacocks, often risking their lives to prevent poaching.
- Bhils, Meenas, and Gonds: While these are significant tribal communities in India with their own cultural practices and relationships with nature, the specific religious mandate and historical fame for protecting Blackbuck herds and Peacocks in the arid regions of Rajasthan is uniquely associated with the Bishnois.
Key Takeaway: The Bishnoi community is historically recognized as India's earliest environmentalists due to their religious obligation to protect wildlife, specifically the Blackbuck and the Khejri tree.
