Most people love nature and consider themselves environmentalists, but nature isn't just pretty and lovable, it is indispensable to our survival and economic activity.That is the most compelling reason for environmental protection. The conventional economic wisdom views land (natural capital) as a small part of the economy, along with capital, labor, technology and so on.The authors argue that this is backwards: that the economy nests within the environment (land) and not the other way around. The authors give a brief history of the origins of conventional economic wisdom and critique it from a the standpoint of ecological economics.They explain what natural capital -our life support system - is and does, and describe the severe strains that have been put on it.They conclude with some policy options, such as green taxes and suggestions for personal action that would conserve natural capital and thus make conserve resources for present and future generations. Natural Capital and Human Economic Survival is written for environmentalists, environmental studies majors and anyone concerned about the flaws of mainstream economics - how it has led us into unsustainable ways of living - and who would like to learn about alternatives that are more sustainable.
