Well, the most common way of turning into a zombie is to be bitten by a zombie. Now, of course, that is if you are not eaten in the process. Zombies are also depicted as the risen dead meaning they arise from people who had previously perished. Another way to become a zombie is if you have been infected by a mutagenic pathogen, especially a virus.
Brought into the mainstream by popularization in movies and video games, the zombie apocalypse might just be one of the most talked about projected occurrences in the United States. It involves the usurpation of the civilized populations of the world by the walking-dead, or rather, the zombies. What this hypothetical projection states is that there will be a global infestation by zombies who are going to be seriously hostile to human life. Unfortunately, many project the infestation rate being faster than the rate at which authorities will respond to the situation. The infestation will lead to a tremendous collapse in the society as a whole. The result this will have is a zombie-infested world with very few human survivors; the living being outnumbered by the dead.
It is thought that many people are giving in into the zombie apocalypse theory as a way of dealing with anxiety over the end of the world and also to use it as a tool to show people that the world in general is not well prepared for disastrous situations as this.
Fans of the various zombie films and video games have been so drawn into the hypothetical zombie apocalypse believed to affect the near future to the point that they are preparing by creating weapons and educating the general public. Weapons range from an array of crude weapons such as clubs (mostly laced with barbed wires or nails) to sophisticated contemporary shotguns. Creation of public awareness includes teaching ways to survive the zombie apocalypse and to learn how to avoid being infected by the zombie virus.
