<i>'Ruth offers a compact, very readable introduction to the booming field of Ecological Economics as it seeks to trace the interdependencies among human activities and environmental change, focusing in particular on industrial market driven economies. With a very modest degree of mathematical formalization, it pays tribute to science disciplines like physics and ecology in understanding the effects of economic decisions on the biosphere, and makes brief but distinct excursions into mainstream economics to mark the specifics of the ecological economic approach.'</i><br /> --Marina Fischer-Kowalski, University of Vienna, Austria<p><i>'Being a diverse field, ecological economics tends to be interpreted in distinct ways by different authors. Ruth offers his own take in this concise treatment that quickly moves beyond basics to make the reader aware of the complications characterizing integrated studies. While one could argue with some of his conclusions, they are always richly laced with arguments and illustrations.'</i><br /> --Jeroen van den Bergh, University of Barcelona, Spain and Vrije Universiteit, the Netherlands</p><p><i>'This</i> Advanced Introduction<i> is introductory because it starts at the beginning. First principles of economics and ecology are united in a pre-analytic vision of the economy as a subsystem of the ecosphere. It is ''advanced'' because it rigorously elaborates that vision to explain ecological economics, with ample references to the literature, and admirable brevity. A splendid contribution!'</i><br /> --Herman Daly, University of Maryland, US</p>
