This is not saying, however, that mankind will be well fed. The 

 social, economic, and political problems are many and difficult. The 

 technical problems of soils, plants, and animals, great as they are, are 

 small by comparison. 



Perhaps the really big question is: How badly do we want abundant 

 food in the world ? How much are we willing to sacrifice now, as 

 individuals, as groups, and as nations? These are the sorts of questions 

 that must be debated in terms of value judgments. They cannot be 

 answered scientifically. What soil science says is that if people want an 

 efficient agriculture, producing abundant food on a sustained basis, 

 and are willing to develop the necessary social institutions, they may 

 have it.
