Download or read book Extinction in Our Times written by James P. Collins and published by Oxford University Press. This book was released on 2009-07-07 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.

Download or read book The Face of the Earth written by J. Donald Hughes and published by Routledge. This book was released on 2015-05-11 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the organizing principle of virtually every world history text is "development", the editor of this volume maintains that this traditional approach fails to address the issue of sustainability. By adopting the ecological process as their major theme, the authors show how the process of human interaction with the natural environment unfolded in the past, and offer perspective on the ecological crises in our world at the beginning of the 21st century. Topics range from broad regional studies that examine important aspects of the global environment that affect nations, to a study of the widespread influence of one important individual on his nation and beyond. The authors take different approaches, but all share the conviction that world history must take ecological process seriously, and they all recognize the ways in which the living and non-living systems of the earth have influenced the course of human affairs.

Download or read book Divided Planet written by Tom Athanasiou and published by University of Georgia Press. This book was released on 1998 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming. Soil loss. Freshwater scarcity. Extinction. Overconsumption. Toxic waste production. Habitat and biodiversity erosion. These are only a few of our most urgent ecological crises. There are others as well and, despite the popularity of good-news environmentalism, few of them are going away. In this wide-ranging, grimly entertaining commentary on the environmental debate, Tom Athanasiou finds that these problems are exacerbated, if not caused, by the planet's division into "warring camps of rich and poor." Writing with passionate intelligence, Athanasiou proposes a simple yet radical solution--stop indulging easy, calming fantasies in which everything seems to change, but nothing important changes at all. Instead, do what needs to be done, now, while there is still time and goodwill. The bottom line, he concludes, is that there will be no sustainability without a large measure of justice. Without profound political and economic change, he argues, there can be no effective global environmental action, no real effort to save the planet.
