WE have been fooling "God and Nature" for centuries. The natural course of "nature" is for disease and famine to control the population. Without our intervention millions would still be dying of smallpox, whooping cough, diphtheria, flu, malaria, etc. Without the development of a process to fix nitrogen artificially we could not produce enough food to feed, by an early 20th century estimate, more than about 6 billion people worldwide. So it is correct that man has altered the true course of nature by developing vaccines and any number of other inventions. We just differ in our beliefs, I prefer to have the inventions and vaccines others do not - and that is their right.
