Exposing children to environmental pollutants during important times of physiological development can lead to long-lasting health problems, dysfunction, and disease. The location of children’s schools can increase their exposure. We examined the extent of air pollution from industrial sources around public schools in Michigan to find out whether air pollution jeopardizes children’s health and academic success. We found that schools located in areas with the highest air pollution levels had the lowest attendance rates—a potential indicator of poor health—and the highest proportions of students who failed to meet state educational testing standards. Michigan and many other states currently do not require officials considering a site for a new school to analyze its environmental quality. Our results show that such requirements are needed. For schools already in existence, we recommend that their environmental quality should be investigated and improved if necessary.

Burgeoning epidemiological, animal, and cellular data link environmental endocrine-disrupting chemicals (EDCs) to metabolic dysfunction. Disproportionate exposure to diabetes-associated EDCs may be an underappreciated contributor to disparities in metabolic disease risk. The burden of diabetes is not uniformly borne by American society; rather, this disease disproportionately affects certain populations, including African Americans, Latinos, and low-income individuals. The purpose of this study was to review the evidence linking unequal exposures to EDCs with racial, ethnic, and socioeconomic diabetes disparities in the U.S.; discuss social forces promoting these disparities; and explore potential interventions. Articles examining the links between chemical exposures and metabolic disease were extracted from the U.S. National Library of Medicine for the period of 1966 to 3 December 2016. EDCs associated with diabetes in the literature were then searched for evidence of racial, ethnic, and socioeconomic exposure disparities. Among Latinos, African Americans, and low-income individuals, numerous studies have reported significantly higher exposures to diabetogenic EDCs, including polychlorinated biphenyls, organochlorine pesticides, multiple chemical constituents of air pollution, bisphenol A, and phthalates. This review reveals that unequal exposure to EDCs may be a novel contributor to diabetes disparities. Efforts to reduce the individual and societal burden of diabetes should include educating clinicians on environmental exposures that may increase disease risk, strategies to reduce those exposures, and social policies to address environmental inequality as a novel source of diabetes disparities.

Large carnivores are threatened worldwide by a variety of human-driven factors, including persecution, which regularly results when they come into conflict with people. Although human activities are almost universally viewed as negatively affecting carnivore conservation, we contend that conservation outcomes for carnivores are improved when social and economic forces reduce the risks associated with these species and facilitate the acquisition of values favorable to their conservation. We make three specific propositions: (1) Societal tolerance for carnivores is affected by the distribution of risks and benefits associated with these species, (2) modernization and its associated social changes reduce the risks associated with large carnivores and their conservation, and (3) modernization induces lasting effects on conservation by changing societal values. We review existing evidence and present cross-sectional data showing that variation among nations in large carnivore conservation outcomes are related to three facets of modernization believed to reduce the risks associated with large carnivores.

The increase of minimally managed vacant land resulting from population loss and the subsequent removal of infrastructure is a reoccurring feature in shrinking cities around the globe. Due to the low frequency and intensity of management, these spaces create a unique environment for plant colonization, establishment, and succession. Herein we refer to these plants and the habitats they form as urban spontaneous vegetation (USV). As a form of urban green space, USV has the potential to provide a number of ecological and sociological benefits to shrinking cities, such as supporting urban wildlife, enhancing the provision of regulating ecosystem functions and services, connecting residents with nature, and improving human health and well-being. Conversely, USV can also support undesirable animals such as vectors of disease, and due to its wild and disorderly appearance, can evoke negative emotions in residents while signaling community neglect. This review aims to explore the potential ecological and sociological tradeoffs of USV within the context of shrinking cities. Through this evaluation, we aim to inform future planning and management to exploit the benefits offered by this resource while minimizing negative outcomes, thereby leading to the enhanced sustainability of shrinking cities worldwide.

This article takes a new approach to studying food access. It combines environmental justice analysis with systems thinking in an examination of the food environment of Detroit. The article reviews food access literature and identifies how each body of scholarship's underlying assumptions help or distort our understanding of urban food environments. The article argues for more comprehensive approaches to studying food access and demonstrates how such approaches can be implemented. We collected data from multiple sources, including ReferenceUSA, Orbis, and the Michigan Department of Agriculture, between 2011 and 2013 to build a database of food outlets in the city. We used SPSS 22 and ArcGIS 10.1 to analyze and map the data. The article analyzes the location of 3,499 food outlets in Detroit, comprising 34 categories food retailers, growers, supply chain, and food assistance programs. The study identified 96 supermarkets or full-line grocery stores; 1,110 small groceries, convenience stores, mini marts, and liquor stores; 279 specialty food stores; 306 pharmacies, dollar, and variety stores; 1,245 full-service and fast food restaurants and other food service outlets; 157 supply chain operations; 206 farms, community and school gardens, farmers' markets, and produce markets; and 100 food assistance programs. The article finds that though Detroit has areas that lack food outlets, the portrayal of the entire city as a “food desert” is misleading. Moreover, the traditional approach of food desert research of using only or primarily the presence or absence of supermarkets and full-line grocery stores to study food access ignores many important venues from which people obtain food. It also ignores the strategies people use to cope with food insecurity and their responses to limited food access.
