Nature Rx: Reemergence of Pediatric Nature-Based Therapeutic Programs From the Late 19th and Early 20th Centuries

Across the United States, physicians are prescribing patients nature. These "Nature Rx" programs promote outdoor activity as a measure to combat health epidemics stemming from sedentary lifestyles. Despite the apparent novelty of nature prescription programs, they are not new. Rather, they are a reemergence of nature-based therapeutics that characterized children's health programs in the late 19th and early 20th centuries. These historic programs were popular among working-class urban families, physicians, and public health officials. By contrast, adherence is a challenge for contemporary programs, especially in socially disadvantaged areas. Although there are differences in nature prescription programs and social context, historical antecedents provide important lessons about the need to provide accessible resources and build on existing social networks. They also show that nature-and its related health benefits-does not easily yield itself to precise scientific measurements or outcomes. Recognizing these constraints may be critical to nature prescription programs' continued success and support from the medical profession.

Optimal climate change: economics and climate science policy histories (from heuristic to normative)

Historical accounts of climate change science and policy have reflected rather infrequently upon the debates, discussions, and policy advice proffered by economists in the 1980s. While there are many forms of economic analysis, this article focuses upon cost-benefit analysis, especially as adopted in the work of William Nordhaus. The article addresses the way in which climate change economics subtly altered debates about climate policy from the late 1970s through the 1990s. These debates are often technical and complex, but the argument in this article is that the development of a philosophy of climate change as an issue for cost-benefit analysis has had consequences for how climate policy is made today.
