Author: Michael L. Power and Jay Schulkin In this sweeping exploration of the relatively recent obesity epidemic, Michael L. Power and Jay Schulkin probe evolutionary biology, history, physiology, and medical science to uncover the causes of our growing girth. The unexpected answer? Our own evolutionary success. For most of the past few million years, our evolutionary ancestors' survival depended on being able to consume as much as possible when food was available and to store the excess energy for periods when it was scarce. In the developed world today, high-calorie foods are readily obtainable, yet the propensity to store fat is part of our species' heritage, leaving an increasing number of the world's people vulnerable to obesity. In an environment of abundant food, we are anatomically, physiologically, metabolically, and behaviorally programmed in a way that makes it difficult for us to avoid gaining weight. Power and Schulkins engagingly argued book draws on popular examples and sound science to explain our expanding waistlines and to discuss the consequences of being overweight for different demographic groups. They review the various studies of human and animal fat use and storage, including those that examine fat deposition and metabolism in men and women; chronicle cultural differences in food procurement, preparation, and consumption; and consider the influence of sedentary occupations and lifestyles. A compelling and comprehensive examination of the causes and consequences of the obesity epidemic, The Evolution of Obesity offers fascinating insights into the question, Why are we getting fatter?

Author: Rob Reich The troubling ethics and politics of philanthropyIs philanthropy, by its very nature, a threat to todays democracy? Though we may laud wealthy individuals who give away their money for societys benefit, Just Giving shows how such generosity not only isnt the unassailable good we think it to be but might also undermine democratic values and set back aspirations of justice. Big philanthropy is often an exercise of power, the conversion of private assets into public influence. And it is a form of power that is largely unaccountable, often perpetual, and lavishly tax-advantaged. The affluentand their foundationsreap vast benefits even as they influence policy without accountability. And small philanthropy, or ordinary charitable giving, can be problematic as well. Charity, it turns out, does surprisingly little to provide for those in need and sometimes worsens inequality.These outcomes are shaped by the policies that define and structure philanthropy. When, how much, and to whom people give is influenced by laws governing everything from the creation of foundations and nonprofits to generous tax exemptions for donations of money and property. Rob Reich asks: What attitude and what policies should democracies have concerning individuals who give money away for public purposes? Philanthropy currently fails democracy in many ways, but Reich argues that it can be redeemed. Differentiating between individual philanthropy and private foundations, the aims of mass giving should be the decentralization of power in the production of public goods, such as the arts, education, and science. For foundations, the goal should be what Reich terms discovery, or long-time-horizon innovations that enhance democratic experimentalism. Philanthropy, when properly structured, can play a crucial role in supporting a strong liberal democracy.Just Giving investigates the ethical and political dimensions of philanthropy and considers how giving might better support democratic values and promote justice.
