Spotlight on Andy Egan - Eating Right: The Ethics of Food Choice and Food Policy
Thought much about food lately? What are the environmental and social consequences of various eating habits? What moral obligations, if any, do we have toward nonhuman animals? Do the answers to these questions generate moral obligations to adopt (or to abandon) particular eating habits? How are our individual and societal decisions about what to eat expressive of aesthetic, moral, cultural, and religious values? What's the moral (and policy) significance of particular cultural culinary tradi-

1.6.4 D. Worker as community developer
In this unit, we look at the roles that are taken when working with young people. We focus on what those working with young people actually do, starting with some analysis of roles. We show that, in the context of work with young people, the term is more than simply a statement about who does what: it also says something about the kinds of relationships we form with young people and the values we bring to our work. We then move on to discuss roles in relation to the ‘bigger picture’ of organ
