Hunting is the practice of pursuing wildlife for food or trade. The species which are hunted are referred to as game, and are usually mammals and migratory or non-migratory game birds.
Hunting can also involve the elimination of vermin, as a means of pest control to prevent diseases caused by overpopulation. Hunting advocates state that hunting can be a necessary component of modern wildlife management, for example to help maintain a population of healthy animals within an environment’s ecological carrying capacity when natural checks such as predators are absent.
For survival purposes, we will consider Fishing a form of hunting animals.
Extinction is the rule. Survival is the exception.
