The tragic thing about the world food problem is that it need not be--and it need not grow,"" asserts Secretary of Agriculture Freeman at the outset of his forthright, forward-look at present programs, national, voluntary and international. He accentuates the positive and minimizes the negative (""The preservation of today's world and all of its people including ourselves, depends upon sharing abundance and technical skills"") as he ticks off in particular what the U.S. has done, needs to do. Control of population is essential; so is production of food where it is to be consumed. Difficulties in agricultural development and the importance of technical assistance are weighed; the food crisis in India receives specific attention. Freeman proposes that we improve nutrition, channel 1.5% of the national income toward development, set up ""Agricorp,"" a private public corporation on the line of Comsat, train volunteers. . . . . Far from the pessimism of the Paddocks, their agonized assessments, or their statistical tabulations (Famine--1975: America's Decision, Who Will Survive?), Freeman applies an alert activism that may gain adherents.
