  fate 
  of 
  lands 
  devastated 
  and 
  despoiled 
  by 
  erosion, 
  which 
  is 
  most 
  often 
  

   associated 
  with 
  war 
  or 
  conquest, 
  stands 
  as 
  a 
  warning 
  to 
  mankind 
  to 
  

   change 
  from 
  an 
  economy 
  of 
  exploitation 
  to 
  an 
  economy 
  of 
  conserva- 
  

   tion 
  — 
  of 
  healing 
  and 
  saving 
  conservation. 
  

  

  We 
  must 
  be 
  fully 
  prepared 
  to 
  defend 
  our 
  sovereignty 
  and 
  liberty 
  

   of 
  action 
  against 
  all 
  aggressors. 
  At 
  the 
  same 
  time, 
  the 
  Americas 
  

   are 
  best 
  situated 
  to 
  make 
  the 
  principle 
  of 
  conservation 
  realistic 
  in 
  

   the 
  use 
  of 
  land 
  resources. 
  Thus 
  interpreted 
  and 
  reduced 
  to 
  works 
  

   of 
  saving 
  soils 
  and 
  waters 
  on 
  the 
  land 
  as 
  necessary 
  to 
  the 
  conserva- 
  

   tion 
  of 
  human 
  resources 
  and 
  values, 
  the 
  principle 
  of 
  conservation 
  

   may 
  be 
  compelling 
  and 
  enticing 
  enough 
  to 
  turn 
  a 
  war-weary 
  world 
  

   from 
  a 
  suicidal 
  frenzy 
  of 
  destruction 
  and 
  carnage 
  to 
  a 
  saving 
  and 
  

   healing 
  conservation. 
  The 
  lands 
  of 
  the 
  earth 
  will 
  record 
  the 
  decision 
  

   of 
  mankind 
  as 
  to 
  this 
  momentous 
  question.
