Plant-based transportation fuels were the focus of extended criticism in the press, especially during 2008 when a portion of the blame for a spike in global food prices was associated with growth of the United States’ corn ethanol industry. The critique is based on an unsophisticated portrayal of the ethical issues at stake in the food security implications of biofuel. Three ethical critiques can be leveled at the food vs. fuel debate. First, although market drivers of biofuels indeed skew consumption of agricultural grains, this is not a problem that is unique to biofuels. Second, the critique does not reflect an adequate understanding of the way that rising food prices and changes in agricultural technology affect the food security of the poorest people. Third, although rising food prices could be beneficial to poor farm producers among the world’s poor, it is unlikely that benefits will materialize in the absence of concerted programs to deliberately select biofuel development strategies that are targeted to strengthen food security for poor and small-holding producers. An adequate agricultural ethics for biofuels will require commitment by both private and public sector biofuel developers to ensure that potentially positive attributes of biofuel development are realized.

As industry and technology proliferate in modern society, sustainability has jumped to the forefront of contemporary political and environmental discussions. The balance between progress and the earth's ability to provide for its inhabitants grows increasingly precarious as we attempt to achieve sustainable development. This book articulates a new agrarian philosophy, emphasizing the vital role of agrarianism in modern agricultural practices. It unites concepts of agrarian philosophy, political theory, and environmental ethics to illustrate the importance of creating and maintaining environmentally conscious communities. The book describes the evolution of agrarian values in America following the path blazed by Thomas Jefferson, John Steinbeck, and Wendell Berry.

In this second edition of The Spirit of the Soil: Agriculture and Environmental Ethics, Paul B. Thompson reviews four worldviews that shape competing visions for agriculture. Productionists have sought increasing yields—to make two seeds grow where only one grew before—while traditional visions of good farming have stressed stewardship. These traditional visions have been challenged by two more worldviews: a call for a total cost accounting for farming and an advocacy for a holistic perspective. Thompson argues that an environmentally defensible systems approach must draw upon all four worldviews, recognizing their flaws and synthesizing their strengths in a new vision of sustainable agriculture. This classic 1995 study has been thoroughly revised and significantly expanded in its second edition with up-to-date examples of agriculture’s impact on the environment. These include extensive discussions of new pesticides and the effects of animal agriculture on climate and other areas of the environment. In addition, a new final chapter discusses sustainability, which has become a dominant idea within environmental studies and agrarian political philosophy.

Nanotechnologies are already interacting with the environment. Scientists and engineers are manipulating matter at the nanoscale, and these nanoscale processes and products are being used by industry in commercially available products. These products are either applied directly to the environment or end up in the environment through indirect pathways. This review examines the state of current environmental risk assessment of nanotechnologies. Nanotechnology is described generally, then both the possible benefits of nanotechnology and the risks are reviewed in a traditional way. Subsequently, a philosophical criticism of the traditional way of looking at risks is offered.
