Cultural appropriation, also called cultural borrowing, has been the topic of much discussion in recent years. Roughly speaking, cultural appropriation happens when someone outside of a cultural or ethnic group takes or uses some object that is characteristic or in some way important to the group without the group’s permission. Individuals who find cultural appropriation unproblematic have often argued that if we express moral criticism of the use of traditional Sami outfits by non-Sami, then we are logically committed to criticize all kinds of habits that are clearly acceptable –such as using jeans, eating pizza or drinking tea. However, we will argue that in many cases that objection is problematic. We point out that if one social habit or practice is prohibited by existing social conventions but another is not, then there is a convention difference between the cases. The convention difference is in turn a morally relevant difference, or so we aim to show. We refer to “moderate conventionalism,” according to which existing social conventions are morally relevant facts that should be taken into account when choosing how to act, whatever the content of the conventions happens to be. The claim is analogous with the traditional view that laws have some moral relevance and binding force independent of their content. _Keywords:_ cultural appropriation, conventionalism, moderate conventionalism, convention difference

The on-going space settlement debate has raised questions whether it is possible to settle other planets, and if it was, is it something humans should do. The problem with this space ethical discussion is that it can easily become too vague. To avoid this problem, we suggest a framework for identifying relevant variables that affect the feasibility constraints and desirability factors of establishing space settlements. The variables we focus on include the settlement stage, scale and time frame. Based on the relevant literature, we take mission cost, survival, habitation, water, in situ resources for food, oxygen and fuel energy and dependence on Earth as feasibility constraints that are relevant for the framework. None of them are hard constraints, but rather soft feasibility constraints that make it difficult to establish a permanent human settlement on Mars in the near- to medium-term future. However, in the past, humanity has achieved goals that first seemed infeasible. To justify the costs and effort, the goal must be highly morally desirable. We discuss five different desirability factors that could help justify the effort but as each framework has unique feasibility constraints, not all of these factors are sufficient or necessary to justify this effort. We argue that some of the desirability factors prominent in space ethical literature are not sufficient or necessary in our framework, and thus, we conclude that the normative grounds for establishing a permanent Mars settlement in the foreseeable future are weak.
