sharing. Compounding this natural response to higher energy costs is the increasing wealth in developing countries (where all remaining economic growth is coming from), which is increasing their appetite for energy intensive protein (largely beef), automobiles, and other modern conveniences, and fueling even higher global energy prices. In some developing countries increasing food costs (due to energy costs) are outpacing economies' abilities to generate wealth and causing social unrest such as the recent Arab Spring uprisings. As befits a book concerned with energy scarcity, Rubin outlines the energy options available to nations, including relevant history and current geopolitical context, and delves into broader environmental issues, including the population and sustainability theories of Malthus and, more recently scientists/authors Paul Ehrlich and James Lovelock. He notes the drawbacks to cap and trade emissions policies and to the Kyoto protocol, delves into how realistic projections for future energy use really are, and ultimately (and optimistically) concludes that economics (diminishing oil use as prices climb) will take care of most of the global warming issue. The book is well edited with few typographical errors, though one in particular made me smile - on page 68 Rubin refers to cheap 'bobbles' shipped from China to developed country markets, which brought to mind the popular bobblehead figures, though he likely meant to use the homonym 'baubles'.
