Public service is a way of life for Americans; giving is a part of our national character. But compassionate instincts and generous spirits aren't enough, says veteran urban activist Robert D. Lupton. In this groundbreaking guide, he reveals the disturbing truth about charity: all too much of it has become toxic, devastating to the very people it's meant to help. In his four decades of urban ministry, Lupton has experienced firsthand how our good intentions can have unintended, dire consequences. Our free food and clothing distribution encourages ever-growing handout lines, diminishing the dignity of the poor while increasing their dependency. We converge on inner-city neighborhoods to plant flowers and pick up trash, battering the pride of residents who have the capacity (and responsibility) to beautify their own environment. We fly off on mission trips to poverty-stricken villages, hearts full of pity and suitcases bulging with giveaways--trips that one Nicaraguan leader describes as effective only in "turning my people into beggars."

This account of the current state of foraging theory is also a valuable description of the use of optimality theory in behavioral ecology in general. Organizing and introducing the main research themes in economic analyses of animal feeding behavior, the authors analyze the empirical evidence bearing on foraging models and answer criticisms of optimality modeling. They explain the rationale for applying optimality models to the strategies and mechanics of foraging and present the basic "average-rate maximizing" models and their extensions.The work discusses new directions in foraging research: incorporating incomplete information and risk-sensitive behavior in foraging models; analyzing trade-offs, such as nutrient requirements and the threat of being eaten while foraging; formulating dynamic models; and building constrained optimization models that assume that foragers can use only simple "rules of thumb." As an analysis of these and earlier research developments and as a contribution to debates about the role of theory in evolutionary biology. Foraging Theory will appeal to a wide range of readers, from students to research professionals, in behavioral ecology, population and community ecology, animal behavior, and animal psychology, and especially to those planning empirical tests of foraging models.
