Conservationists would do well to demand more active help from scientific 

 institutions supported by public funds. Thus the invention of apparatus for 

 efficient conversion of wood into fuel gas for use on farms would generate a 

 powerful incentive for keeping the woodlot productive, and incidentally keeping 

 it fit for game. Yet nobody is thinking about such things.
