Zombies+and+Population

For most reasons it is unknown when the bodies of the recently deceased are rising from the grave. Anyone who dies during a zombie plague returns as walking dead. The limitation of the dead is showed by how decayed that body is. A skeleton cannot return as there is no muscle and sinew to move the bones, and no brain to drive it. It could be a virus, maybe chemicals, but all we know it's dead people getting up again.



What would a "zombie" just one do to the population? Just one zombie could do the job. A transfer of blood, spit or any other body fluids could kill you and turn you into one of them. If one zombie bites another then there would be 2 then 4 then 8 then 16 next thing you know there are thousands of them everywhere. Later they will over run the government, then no power, water, heating, or air conditioner. The few people that are left will not only have to worry about the undead monsters striving for their brains but now food and heating and housing.
