One main issue within environmental ethics is the so-called Demarcation Problem, i.e. the question of which entities are members of the moral community and hold intrinsic value. I argue that the demarcation problem relies mainly on Kantian moral philosophy. While the Kantian framework offers a strong and immediately deontological argument for moral agents holding inherent moral values, it presents problems when stretched beyond its original scope and lacks an adequate ground for addressing relational complexity and the moral significance of collectives. (...) In this paper I outline an alternative axiological framework ('map of moral significance') that relies on a relational ontology and encompasses intrinsic and relational values as the two equipollent axes of a matrix in which to embed the question posited by the Demarcation Problem.

In this paper I will examine two responses to the argument from marginal cases; the argument from kinds and the similarity argument. I will argue that these arguments are insufficient to show that all humans have moral status but no animals do. This does not prove that animals have moral status but it does shift the burden of proof onto those who want to maintain that all humans are morally considerable, but no animals are.

A number of philosophers have found inspiration in the writings of Alfred Whitehead to develop their ideas on environmental and animal ethics. I explore the writings of Charles Hartshorne and Daniel Dombrowski to address the question of whether Whiteheadians should be vegetarians. I conclude that there is a morally relevant distinction between plants and animals, based on the Whiteheadian view that animals have higher grades of experience, and that this distinction grounds a moral duty to adopt minimal moral veganism.
