Global human population expansion is rooted in a remarkably successful evolutionary innovation. The neolithic transformation of the natural world gave rise to a symbiosis between humans and their domesticated plant and animal partners that will expand from a current 20 per cent to 60 percent of terrestrial biomass by the middle of the coming century. Such an increase must necessarily be accompanied by a concomitant decrease in wildlife biomass. We suggest that current trends in population growth are unlikely to abate (...) for three reasons: first, there are intrinsic biological pressures to reproduce regardless of social engineering; second, the character of the domestic alliance makes it a formidable competitor to wildlife; and third, the timeframe before population doubling is, from a biological perspective, virtually instantaneous. This paper draws from a wide body of research in the biological and social sciences. We neither condone nor endorse this picture of inexorable population increase. Rather, we appeal for a change in the nature of the discussion of population among environmentalists, to focus on the question of how best to manage what wildlife will be left on the margins of a domesticated world.

I show how the Taoist philosophy, as examplified by both Lao Tzu and Chuang Tzu, is capable of providing a metaphysical foundation for environmental ethics. The Taoist concept of nature, the notions of ontological equality and axiological equality of beings, together with the doctrine of Wu Wei can fulfil, at least in a preliminary way, our purpose. The notion of a minimally coherent ethics is introduced and is shown to be pertinent to the construction of an ethics which bears a (...) close relationship to science. (shrink)

_Being Human _examines the complex connections among conceptions of human nature, attitudes toward non-human nature, and ethics. Anna Peterson proposes an "ethical anthropology" that examines how ideas of nature and humanity are bound together in ways that shape the very foundations of cultures. Peterson discusses mainstream Western understandings of what it means to be human, as well as alternatives to these perspectives, and suggests that the construction of a compelling, coherent environmental ethics will revise our ideas not only about nature (...) but also about what it means to be human.
