I should note that I am pro-vaccine and hope no one misunderstood my position on the matter.

@Gwiz--a lot of diseases simply evolve, and a lot can and do last years without a host, or they live within an unknowing host. Also, there will always be hosts available because there is a certain impossibility with vaccinating everyone in the world. 7 billion is a great a number…

@Geesus Freak--I agree with everything you said. When I speak of nature's wrath, I am speaking of the impossibility of overcoming nature in many circumstances.

And well researched, you got me on the eradication of smallpox. Smallpox, thankfully, seems to be one of those diseases that, while highly contagious without vaccines, was pretty much dead without active hosts. So we can be grateful that smallpox's severe limitations and the vaccine killed it off. I will also add that we eradicated rinderpest too (A cattle disease.)

(Although undocumented cases of smallpox may exist, I have to agree with you, since the proof does not support my old position--it is possible that two diseases have been eradicated.)

However, I am not impressed that we got rid of one infectious disease that targets humans out of the current number of available maladies. Nor are we certain that smallpox will never again be a future problem.

But I digress. As far as childbirth and mortality... That is one part of nature that can be controlled easily. I wouldn't classify that as a wrath of nature. Hurricanes, floods (Some of which man tried to prevent and caused more of...like a plastic bag clogging a storm drain...) Diseases, stupidity, etc...All those are nature's way of saying, "Die. No just kidding. Seriously, just die
