Biodiversity studies comprise the systematic examination of the full array of different kinds of organisms together with the technology by which the diversity can be maintained and used for the benefit of humanity. Current basic research at the species level focuses on the process of species formation, the standing levels of species numbers in various higher taxonomic categories, and the phenomena of hyperdiversity and extinction proneness. The major practical concern is the massive extinction rate now caused by human activity, which (...) threatens losses in the esthetic quality of the world, in economic opportunity, and in vital ecosystem services.

This paper details many ways in which this input has been inadequate, especially during the Bush administration. It also recounts examples of successful use of scientific inputs, and discussed the reasons for both successes and failures. Then it proposes ways to accomplish the critical task of seeing to it that science is properly considered in the policy process.

A few years ago, I wrote on the need for expansion of the environmental areas of bioethics, and covered some of the topics touched on here. Sadly, although it is possible to find some notable exceptions, bioethics does not provide much of an ethical base for considering human-nature relationships. Here I’m not going to deal with these philosophical issues or others about the nature of ethical decision-making. The rapid worsening of the human predicament means that applied ethical issues with a (...) significant environmental connection (what I call “ecoethics”), must be dealt with without waiting for the more interesting theoretical issues to be resolved. I define ecoethics very broadly to deal with dilemmas over a vast range of scales, and believe they now should penetrate virtually all areas of human activities. Ecoethics must struggle with issues of intra-generational (and interperson/group/nation) equity and the dilemmas of discounting by distance (valuing distant persons/events/costs/benefits less than those closer to the observer in physical or mental distance). Ecoethics also deals with the difficult dilemma of inter-generational equity—of discounting the future. That is especially troublesome when actions today can have significant environmental consequences 50 or more generations from now. Here I would like to highlight the ubiquity of those questions and the importance of seeking answers. (shrink)
