Duties and Priority Principles of Taylor's Biocentric Egalitarian Individualism

Questions: How should we treat nonhuman organisms? And most poignantly, if nonhuman organisms have inherent worth equal to humans, how are we to resolve conflicts between them and us?

Taylor's Biocentrism involves the following prima facie (i.e., overridable) duties and moral rules:
(The first two were not discussed in the class reading, nor was distributive justice.)

Taylor is well aware that humans must harm other organisms and interfere with their lives in order to live and thrive. Thus Taylor proposes the following principles to help guide us when interacting in harmful ways with nonhumans:

Taylor's environmentalist argument for vegetarianism: (If plants are as important as animals, which should we eat?) Taylor sees the morality of eating as a question of distributive justice (fair sharing of the planet's resources with other creatures). Since nourishing ourselves by eating vegetables directly requires much less surface of the earth than does growing the vegetables, feeding them to animals, and then eating the animals (a highly inefficient way to get our protein), respect for nature requires a vegetarian diet (despite the equal inherent worth of plants and animals). The reduction in cultivated land that would be achieved by moving from a meat-eating to a vegetarian culture would help achieve a more equal sharing of the planet with other organisms.

Note: Taylor allows us to sacrifice the basic interests (life, health) of nonhuman organisms for the less basic (but significant) interests of humans (education, transportation, energy) as long as those interests are "intrinsically compatible with respect for nature" (and if we also satisfy the principles of minimum wrong, distributive justice, and restitutive justice). For example, he would allow destroying habitat in order to build a library. (For other examples, see his list.)
