Friends!! It is sad when a majestic animal like tiger is fighting for survival.
Time and again history has proved that unconcern for other lives, which is selfishness to the core, brings one's own destruction. In the Ramayana, Sage Vashishta advises Lord Rama that it is the duty of the king to protect not only the subject of his state but also all natural resources which include flora and fauna. Otherwise you are inviting trouble for your kingdom.
Isn't it an apparent paradox that the highest evolved creature called 'man' does not hesitate to exploit nature for his personal gains where as all other creatures who do not have thinking capacity fall in line with nature quite naturally.
Every creature has right to co-exist in this world. Merely possessing intelligence does not justify inhuman actions of humans.
