I do not buy SB's notion that various wild animal species affected by plagues are somehow "deficient". These beings are affected by survival of the fittest so are the best they can be.
Please allow me to elaborate a little further, so I am not misunderstood, I am not suggesting that all disease (naturally occurring or man made) stem directly from nutritional imbalances, though I insist that such factors play an important role in disease pathology. There are indeed a multitude of other factors which lead to what has been referred to as plagues ( non of these factors in my opinion being due to the lack of vaccines)
Nothing occurs in isolation, and an aberrant strain of pathogenic organisms cannot and will not gain a foothold in order to launch all out genocide upon a species unless there are the right environmental conditions. The totality of biological environmental factors can never be( at least not yet) fully taken into account by our limited understanding of the nature of life from a holistic perspective.
Pandemics in the past have been blamed on microbial infection alone, and other very important contributing factors have been completely ignored. During the black death, there was a mini ice age, and many of the crops were infected with poisonous molds, while many of the people lived in abject squalor. Yes many died a horrible death, but we should not forget that many survived, and there were some parts of Europe where people still lived indigenously that didn't suffer at all. There is also a lot of evidence that suggest during times of plague those who survive gain genetic adaptions which pass on immunity to subsequent generations. ( this could explain why many with people with bloodlines from plague survivors are completely immune to diseases like AIDs.)
Though it is correct that epidemics and blights have wiped out large numbers of creature from all animal kingdoms, the issue does not stem from a lack of artificial immune stimulation, through vaccination. There are and have always been subtle and constant variations within the micro and macro biomes of earth. From time to time there are naturally occurring shifts in the balance, something may happen that causes a change in the microbial ecology( some new mold, fungus , or bacteria emerges and being opportunistic and pernicious, may take advantage of a slight change, which may be imperceptible to our scientific understanding, yet this slight environmental change is enough to upset the balance of entire ecosystems, and often times through no fault in genetic design there are certain species that get broad sided, by something they have never encountered before and there is a die off. Though usually this will not lead to extinction, and the survivors will become perfectly readapted to the new environment and their offspring will once again thrive, within harmony and balance with the organisms that nearly killed their grandparents.
These kinds of naturally occurring die offs, and viral purging of entire species, have occurred through the course of evolution, I insist that it is a necessary part of life, and by directly attempting to suppress the realignment process without fully understanding all the interconnections, we are making grave mistakes. By using vaccinations and drugs to suppress the proses of evolution and adaption(which are often horrid, crawl and painful from a human perspective) We are only kicking the can down to the next generation, and if we continue on this path, then there will come a time when the human race will not be able to survive without cradle to grave medical scientific intervention.
The choice is up to us. We can learn to realign with nature, and accept the inevitability outbreaks of viral realignments, and learn ways to best cope with the painful possess of evolution that wont be of determent to future generations. By doing so we can take our attention away from the dead end of germ theory, and develop modes and methods by which to optimize our capacity for peak immunity which will allow us to harmonize with life on earth as it is, with all the creatures and microbes as they are, without feeling compelled to dominate and mutilate the structure of nature to please our apish whims. By letting nature lead the way and using our powers of understanding and intuition we could much better learn the lessons that mother earth has to teach us. Let us not be lead so far away from Gaias womb, by the delusions of the modern humans who believe that we no longer need to be suckled in her bosom, inoculated by her maternal antibodies, which have sustained us through the eons.
We must learn to recognize these affronts, and refuse to go along with people who pose as humanities saviors, full of pretension and arrogance, that insist indefatigable that science alone will provide the formula that will meet all our needs, and that all we must do, as the uneducated public, is to allow the lab coats to continue on with their experimentations unquestioningly.
