Throughout history, a disease pops up once in a while that wipes out sizeable chunks of the human population and fills every living soul with horror and dread: Cholera, smallpox, measles, ebola, influenza, herpes, HIV.
After the epidemic has swept across the earth and populations have been decimated, the individuals who survive arise from the ashes stronger, wiser and, sometimes, immune from future attacks. But what is often forgotten amid the heartbreak and tears is that such disease epidemics are Mother Nature’s way of purging itself of excess human population.
