"Flood control dams have no relation to the cause of floods. Check dams and 
 terraces do not touch the cause of erosion...The practices we now call  
conservation are, to a large extent, local alleviations of biotic pain. They 
are  necessary, but they must not be confused with cures." (Aldo  Leopold)
