"We may thoughtlessly reckon our animal 

 tragedies, the visitations of terrifying, 

 wealth-sapping diseases, in terms of fiscal 

 economy only; but in the annals of history, 

 animal diseases influence the destiny of 

 Nations. They are at the roots of famines, 

 plagues, wars, overturned governments and 

 the lapse of civilizations." 



Merillat and Campbell
