Even within the age of the Anthropocene Man and wildlife have all the time resided in quiet concord within the Sundarbans. The rising human inhabitants usually encroaches into the tiger territory and typically the tigers additionally wander out searching for meals. The rise in tiger density will certainly hamper the long-existent concord between each species.
