Bishnois, a community following the tenets prescribed by Jambeshwar in the 15th century, teaches its followers to respect nature, be kind to animals and not to cut trees. The followers are so principled as to lay down their lives to protect a tree.
Bishnois do not cut or lop green trees; instead they use dried cow dung as fuel. They do not cremate their dead as Hindus normally do, because it involves the use of firewood; instead, they bury them. Agriculture is the mainstay of the people; they also carve wood during the time they are not busy on their fields. The required wood comes from trees that have have fallen during storms. Each Bishnoi family creates a tank in their field to provide water for black bucks and antelopes
in the arid summer months. They maintain groves for the animals to graze and birds to feed. Solar energy is used to extract underground water to irrigate the groves. The region where they live is a desert (Thar desert), and these groves help to recharge rain water in the aquifers in the desert.
