410 BIOLOGY AND HUMAN LIFE 



Less frequently do we consider as health workers the many 

 people who supply us with our food, our clothing, our fuel, our 

 housing ; yet every one of these, from the plowman and shep- 

 herd and lumberman and miner to the cook and clothing de- 

 signer and architect, can do something that either helps or 

 hinders the health of the community. It is necessary to pro- 

 duce an abundance of food, to preserve it, and to prepare and 

 serve it most effectively; it is necessary to build houses that 

 can be properly ventilated and heated or cooled ; it is necessary 

 to make suitable clothes ; and so on. These things are so essen- 

 tial to health and well-being that we take them for granted. 

 By the division of labor everyone who is of any service at all 

 may be of service to health. We must work ; our work should 

 therefore be as helpful as possible in promoting the health of the 

 worker and the welfare of all.
