So, I  suspect that the big issue is that this is a huge monoculture.   In  
IL, you can drive from east to west across much of the state and see  
nothing  
but corn.  


Is there no crop rotation? How do they avoid build up of pests and diseases 
 and exhaustion of nutrients?  More and more chemicals I suppose. How do  
bees get any propolis?
