Half the world is suffering needlessly from hunger, ""so,"" the author confesses, a farmer writes a book"". Farmer cum agriculturist cum government expert, Garst hails from that celebrated Iowan farm at Coon Rapids where Khrushchev marvelled at the food-producing success of the New World Capitalists. With real experience, a down-to-earth style and country optimism, Garst makes his thesis a simple one: The present-day world population can be well-fed and, in addition, can be halted in its explosive growth, not by Malthusian hunger, but by adequate food. The methods of modern food production and the means for conveying and applying these to undeveloped areas are discussed in an elementary, but definite and practical, manner. Hybrid seed-corn may have been ""a real cranium cracker"" when introduced, but now it, as well as the use of fertilizers, cattle reed, and commercial markets, can bring relief to the underfed legions of the world. Examples are given in South America and India; Garst emphasizes the role of American know-how in fostering modern methods of food production as ""one thing Americans can do"". Why not a U.S. demonstration farm in Brasilia to give the Alliance for Progress some real corn-fed support? Why not get practical, leave our hydroelectric projects, and help where we can? The suggestions are succinct, the agricultural knowledge concrete and the presentation perfect for the layman (and perhaps a government ""expert"" or two"").
