In this paper, I undertake a conceptual analysis of ordinary usages of the concepts of “litter” and “pollution.” If “litter” or “pollution” applies to space debris in its various contexts, then in dealing with space debris as an ethical concern, we may more neatly apply arguments for the wrongness of litter and pollution to these new contexts. After engaging in a conceptual analysis of “litter” and “pollution,” I consider whether these concepts apply to space debris, examining three contexts: (1) surface (...) debris on Moon and Mars, (2) intentionally crashing objects into gas giants, ice giants, and stars, and (3) the pressing issue of orbital space debris. I conclude by finding that neither “litter” nor “pollution” cleanly applies to any of these three contexts. (shrink)

This paper approaches the question of terraforming—the changing of extraterrestrial environments to be capable of harboring earth-based life—by arguing for a novel conception of moral status that accounts for extraterrestrial bodies like Mars. The paper begins by addressing pro-terraforming arguments offered by James S. J. Schwartz before offering the novel account of moral status. The account offered builds on and modifies Keekok Lee’s No External Teleology Thesis (NETT), while defending a proposed Non-Fungibility Thesis (NFT). The NETT is modified and defended (...) with specific reference to Lee’s work on artifactuality and transgenic organisms. The NFT builds on work around objectification and irreplaceability, offering an account that recognizes the importance of bearers of value above and beyond the mere value they purportedly possess. Finally, the plausibility of the account is established by an overview of its applicability to other possible candidates for moral status. (shrink)

De-extinction technology aims to bring extinct species back into existence, often with the goal of releasing created organisms into natural environments. In this paper, I argue that there are aesthetic reasons to avoid engaging in de-extinction and release projects, even if they pass moral permissibility criteria. The strength of these reasons depends on conclusions regarding species authenticity - a problem that arises at the intersection of de-extinction technology and the 'species problem' in the philosophy of biology. Since species authenticity affects (...) the perceived naturalness of 'natural' environments, and thus the aesthetic judgments thereof, I contend that there will be negative aesthetic consequences of de-extinction efforts that ought to be further explored before such projects move forward.
