BIOLOGICAL PROBLEMS 



so long as the danger lasts we may rely on the farmer 

 not to put profit before food, but to raise as much 

 food as possible. 



In the old days British fiscal and social conditions 

 made it more profitable to grow food for animals 

 than for men. Out of 46! million acres of land in 

 cultivation in the United Kingdom only about 

 5 millions directly produced human food and nearly 

 42 millions produced animal food no less than 

 34 millions being grass. 



Our food-supply during the five years preceding 

 the war (1909-13) was as follows: 



FOOD OF THE UNITED KINGDOM: MILLION 

 TONS PER ANNUM 



Thus we obtained from all sources 120 million tons 

 of animal food, most of which was grown at home, 

 and a little over 22 million tons of human food, more 

 than half of which was imported.
