The continuing existence of zoos and their good purposes such as conservation, science, education, and recreation, can be ethically justified only if zoos guarantee the welfare of their animals. The usual criteria for measuring animal welfare in zoos are physical health, long life, and reproduction. This paper looks at these criteria and finds them insufficient. Additional criteria are submitted to expand the range of welfare considerations: natural and abnormal behavior; freedom and choice; and dignity. All these criteria should play a (...) role in analyzing zoo animal welfare and interests but dignity has the overriding part because it impacts on both animal and human interests. (shrink)

Ethical reflections help us decide what are the best actions to pursue in difficult and controversial situations. Reflections on public policy consider how to alter patterns of individual activity and institutional policies or frameworks for the better. The rising prevalence of childhood and adolescent obesity may pose serious health issues. As such, it is related to ethical and public policy questions including responsibility for health, food production and consumption, patterns of physical activity, the role of the state, and the rights (...) and duties of parenthood.

The methodology of the IDEFICS (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants) study raises a number of important ethical questions. Many of these are already well recognised in ethical guidelines that uphold principles of individual and parental consent, confidentiality and scientific review. There are, however, wider issues that require ethical reflection. In this paper, we focus on a set of problems surrounding the evaluation of complex social interventions, and argue that comprehensive and objective evaluation (...) is a much more ethically charged aim than it may first appear. In particular, we contend that standard scientific measures - of body size and biomarkers - convey only part of the story. This is partly because, when we intervene in communities, we are also concerned with complex social effects. These effects are made even more complex by contemporary social anxieties about fat and physical appearance, as well as about the safety and security of children. Such anxieties increase the risk of undesirable side effects that are themselves difficult to gauge. In the face of these and other complexities, we argue that the evaluation of interventions should involve a strong ethical dimension. First, it must include - as does the IDEFICS study - consideration of the opinions of the people affected, who are subjected to interventions in ways that necessarily go beyond individual consent. Second, we suggest that interventions might also be assessed by how much they empower people - and especially those persons, such as children, who are otherwise often disempowered. (shrink)
