This article discusses the appeal to infinite value in environmental decision making. We argue that invoking infinite values as a means of faithfully representing the worth of certain parts of the natural environment is a mistake. Infinite values have a number of theoretical and practical problems associated with them. For example, we show that invoking infinite values makes it hard to motivate...
متن کاملEvaluation of the Valuable Oxygenated Components in Iranian Rose Water
Rose water is one of the most important products obtained from Rosa genus (Rosaceae). Although Iran is one of the main producers of rose water, limited research has been done on it. A simple distillation and a Clevenger-type apparatus were used to obtain rose water and rose oil. All the volatile concentrates were investigated for their chemical composition by gas chromatography (GC) and gas chr...

متن کاملA model-based integrated assessment of land degradation by water erosion in a valuable Spanish rangeland
This paper presents an integrated assessment model aimed at evaluating land degradation by water erosion in dehesa rangelands in the Iberian Peninsula. The model is built following the system dynamics approach. The degradation risk is likened to the probability of losing a certain amount of soil within a number of years, as estimated over a great number of stochastic simulations. Complementary ...
