Striving to be a health ranger, I found Mike Adams, a true guru in this department. 

''Sons of Adam'' is based on a tv horror movie called ''The Screwfly Solution.''  The screwfly solution is an airborn microbial vector, which infects men, and fuses neurological centers, such that every sexual stimulus turns into a unstopped urge to kill.  This effectively eliminates the human species, leaving the rest of nature  untouched.
