  1. Helena Siipi (2013). Is Natural Food Healthy? Journal of Agricultural and Environmental Ethics 26 (4):797-812.
    Is food’s naturalness conceptually connected to its healthiness? Answering the question requires spelling out the following: (1) What is meant by the healthiness of food? (2) What different conceptual meanings the term natural has in the context of food? (3) Are some of those meanings connected to the healthiness of food? In this paper the healthiness of food is understood narrowly as food’s accordance with nutritional needs of its eater. The connection of healthiness to the following five food-related senses of (...)

    The European Union’s policies regarding genetically modified food (GMF hereafter) are based on the precautionary principle and the requirement of respecting consumers’ autonomy. We ask whether the requirement of respecting consumers’ autonomy regarding GMF implies that both GMF and non-GMF products should be available in the market. According to one line of thought, consumers’ choices may be autonomous even when the both types of products are not available. A food market with only GMF or only non-GMF products does not strictly (...)

  8. Helena Siipi (2008). Dimensions of Naturalness. Ethics and the Environment 13 (1):pp. 71-103.
    This paper presents a way of classifying different forms of naturalness and unnaturalness. Three main forms of (un)naturalness are found as the following: history- based (un)naturalness, property-based (un)naturalness and relation-based (un)naturalness. Numerous subforms (and some subforms of the subforms) of each are presented. The subforms differ with respect to the entities that are found (un)natural, with respect to their all-inclusiveness, and whether (un)naturalness is seen as all-or-nothing affair, or a continuous gradient. This kind of conceptual analysis is needed, first, because (...)

    Individuals’ food choices are intimately connected to their self-images and world views. Some dietary choices adopted by consumers pose restrictions on their use of genetically modified food (GMF). It is quite generally agreed that some kind of labeling is necessary for respecting consumers’ autonomy of choice regarding GMF. In this paper, we ask whether the current practice of mandatory labeling of GMF products in the European Union is a sufficient administrative procedure for respecting consumers’ autonomy. Three issues concerning this question (...)

    Decline of biodiversity—richness, variety and variability of living beings—is an issue of concern world wide. Nevertheless, not all biological diversity is valued by conservation biologists. Most of them reject an idea of creation of so called A-areas—i.e. maximally rich and diverse biotic areas which have been produced by methods like genetic engineering and species introduction. Reasons for this are considered. A-areas are artefacts: their existence has been intentionally brought about by intentionally modifying their properties in order to produce an entity (...)

    Conservation scientists are arguing whether naturalness provides a reasonable imperative for conservation. To clarify this debate and the interpretation of the term natural, I analyze three management strategies – ecosystem preservation, ecosystem restoration, and ecosystem engineering – with respect to the naturalness of their outcomes. This analysis consists in two parts. First, the ambiguous term natural is defined in a variety of ways, including (1) naturalness as that which is part of nature, (2) naturalness as a contrast to artifactuality, (3) (...)
