Sufficient food is available to provide everyone on earth with a nutritionally balanced diet. A document on strategies takes a "design science" approach to food problems; this approach views interrelationships of economic and social problems from a global scope and attempts to solve them with systematic alternative approaches. Although the major focus is on food and the world, other factors such as energy, health, education, transportation and economics are considered. Food sources and food distribution are examined. Topics such as aquaculture, leaf protein, new foods etc., are described generally. Advantages, disadvantages and steps for further development are listed for each topic. Suggestions on ways individuals and groups can contribute to solving local and world food problems on a small scale are given. Numerous charts and tables reinforce statements. References follow each chapter. (rkm).
