Wildlife is the natural creature of the nature. It has no education, no morality as well as complete sympathy on human. Carnivorous animals such as tiger and bear attack in Bangladesh are very common. In Sundarbans and its adjacent areas there are lots of incidences of tiger attack. Royal Bengal Tiger (Panthera tigris) and Asian Elephant (Elephas maximus) in Sundarbans and Asian Black Bear (Ursus thibetanus) in Chittagong Hill Tracts are common animal attack on human. Illegal entry in those forests, hunting or killing and deforestation are the main causes for these attacks. Tiger attack was the first then elephant and finally bears.

Tiger can be man eater, elephants are man-screamer and bears are being considered man-injurious. For avoiding such conflicts we may apply some methods.
