Aquaculture is the fastest growing animal producing sector in the world and is expected to play an important role in global food supply. Along with this growth, concerns have been raised about the environmental effects of escapees and pollution, fish welfare, and consumer health as well as the use of marine resources for producing fish feed. In this paper we present some of the major challenges salmon farming is facing today. We discuss issues of relevance to how to ensure sustainability, (...) by focusing on animal production systems, breeding approaches, sources for feed ingredients, and genetic engineering strategies. Other crucial issues such as animal welfare, environmental quality, and ethics are elaborated with regard to relevance for the sustainability of aquaculture. Additionally, we comment on socio-economic distributive implications by intellectual property rights (IPR) strategies on access to genetic material and traceability. To improve sustainability of salmon farming we suggest that there is a need for new approaches to guide research, for identification of ethical issues, and for engaging stakeholders in resolving these challenges.

The Patient Protection and Affordable Care Act (ACA) turns to a nontraditional mechanism to improve public health: employer-provided financial incentives for healthy behaviors. Critics raise questions about incentive programs' effectiveness, employer involvement, and potential discrimination. We support incentive program development despite these concerns. The ACA sets the stage for a broad-based research and implementation agenda through which we can learn to structure incentive programs to not only promote public health but also address prevalent concerns.
The argument in this essay is twofold. (1) Procedural justice requires,in particular cases, that we restrict property rights in natural resources, e.g., California agricultural land or Appalachian coal land. (2) Conditions imposed by Locke's political theory and by dense population require,in general, that we restrict property rights in finite or non-renewable natural resources such as land. If these arguments are correct, then we have a moral imperative to use land-use controls (such as taxation, planning, zoning, and acreage limitations) to restructure (...) land ownership and land use in a far more radical way than has ever been accomplished in the past.

One way to do socially relevant investigations of science is through conceptual analysis of scientiﬁc terms used in special-interest science (SIS). SIS is science having welfare-related consequences and funded by special interests, e.g., tobacco companies, in order to establish predetermined conclusions. For instance, because the chemical industry seeks deregulation of toxic emissions and avoiding costly cleanups, it funds SIS that supports the concept of “hormesis” (according to which low doses of toxins/carcinogens have beneﬁcial effects). Analyzing the hormesis concept of its (...) main defender, chemical-industry-funded Edward Calabrese, the paper shows Calabrese and others fail to distinguish three different hormesis concepts, H, HG, and HD. H requires toxin-induced, short-term beneﬁcial effects for only one biological endpoint, while HG requires toxin-induced, net-beneﬁcial effects for all endpoints/responses/subjects/ages/conditions. HD requires using the risk-assessment/ regulatory default rule that all low-dose toxic exposures are net-beneﬁcial, thus allowable. Clarifying these concepts, the paper argues for ﬁve main claims. (1) Claims positing H are trivially true but irrelevant to regulations. (2) Claims positing HG are relevant to regulation but scientifically false. (3) Claims positing HD are relevant to regulation but ethically/scientifically questionable. (4) Although no hormesis concept (H, HG, or HD) has both scientiﬁc validity and regulatory relevance, Calabrese and others obscure this fact through repeated equivocation, begging the question, and data-trimming. Consequently (5) their errors provide some undeserved rhetorical plausibility for deregulating low-dose toxins. (shrink)
