Abstract: | Abstract: Passage of environmental legislation often creates a state of euphoria among supporters such that implementation programs are not rigorously evaluated Endangered species and water resource legislation are two examples of sound environmental legislation with major weaknesses in their implementation. Regulations to implement the US. Clean Water Act, for example, emphasize water quality (physical and chemical properties of water) by calling for uniform standards for contaminants rather than the broader goal of improving the quality of water resources. As a result, improvements in the quality of water resource quality have been limited despite massive expenditures. Natural resource agencies' narrow emphasis on harvested and threatened and endangered species has similar consequences. Unless a comprehensive and rigorous definition of the goals of biodiversity legislation is developed and adhered to by regulatory agencies, efforts to implement biodiversity legislation could lead to similar problems. Protection of biodiversity should be considered a subset of the need to protect the biological integrity of natural resource systems and the ecological health of the biosphere. Programs to protect biodiversity should reflect that more holistic goal and include provisions for evaluating success at attaining stated goals and for making midcourse adjustments in programs when resources are not being adequately protected. |
