Book Description
Excerpt from Transaction Sand Proceedings of the New Zealand Institute, 1869, Vol. 2 The first volume of the Transactions contained several Communications and Essays that had accumulated from previous years, and it was therefore anticipated in the Preface that the succeeding volumes would not equal it in size. The present issue, however, has not fallen off in this respect, as it contains almost an equal number of pages, which are of larger size while the number of original Articles has increased from twenty-three to sixty-three, contributed by thirty-two different authors. The arrangement of the work has been improved by dividing it into Sections, according to the subjects treated of.

Book Description
Excerpt from Transactions, Vol. 2 Address of the President of the Warren Academy of Sciences at the Eighth Annual Meeting, October 20, 1911. In my paper tonight I shall first touch upon a few notions of modern scientists regarding the now available sources of energy, some of which are eternal in their potency; others doomed in time to pass away and become a matter of ancient history. In a paper of this nature I cannot treat the matter exhaustively, - nay, I am not capable, if I chose, to do so. I shall merely try to indicate in a general way the trend of science in its search for cheap, economi cal sources of power, and point out some of the means which science will in future be forced to utilize as sources of energy - forced to use them for at least two reasons: first, because they will prove more efficient and economical, producing higher per cent of work from the total energy applied, second because the world's failing supply of fuel will render such economy an absolute necessity. That the resources of the earth are limited is well understood. We derive all our energy directly or indirectly from the sun, whether by using wood, coal, oil, gas, or energy generated by water power. Let us consider these for a moment. The use of wood as a fuel is, of course, a limited matter and as civilization advances and its vanguard destroys the forests, the available wood is rapidly con sumed. What is left must be carefully conserved and husbanded for future lumber. The use of wood as fuel, then, must largely cease in future. The same with oil and gas. In Warren we can well understand the case. The supply of oil and gas is not indefinite nor infinite, and, so far as we know, is not recuperating in quantity in any way, to replace what is used. New fields and large ones may be discovered but the time will ultimately come when there will be no oil, no gas.

Book Description
We are pleased to announce a new series of environmental history readers, suitable for students. Comprising essays selected from our journals, Environment and History and Environmental Values, each inexpensive paperback volume will address an important theme in environmental history, combining underlying theory and specific case-studies. The first volume, Bio-invaders, investigates the rhetoric and realities of exotic, introduced and 'alien' species. The book comprises a number of general essays, exploring and challenging common perceptions about such species, and a series of case studies of specific species in specific contexts. Its geographical coverage ranges from the United Kingdom to New Zealand by way of South Africa, India and Palestine; and the essays cover both historical and recent introductions.

Book Description
"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant

Book Description
"Book and man are brilliant, passionate, optimistic and impatient . . . Outstanding." —The Economist The landmark exploration of economic prosperity and how the world can escape from extreme poverty for the world's poorest citizens, from one of the world's most renowned economists Hailed by Time as one of the world's hundred most influential people, Jeffrey D. Sachs is renowned for his work around the globe advising economies in crisis. Now a classic of its genre, The End of Poverty distills more than thirty years of experience to offer a uniquely informed vision of the steps that can transform impoverished countries into prosperous ones. Marrying vivid storytelling with rigorous analysis, Sachs lays out a clear conceptual map of the world economy. Explaining his own work in Bolivia, Russia, India, China, and Africa, he offers an integrated set of solutions to the interwoven economic, political, environmental, and social problems that challenge the world's poorest countries. Ten years after its initial publication, The End of Poverty remains an indispensible and influential work. In this 10th anniversary edition, Sachs presents an extensive new foreword assessing the progress of the past decade, the work that remains to be done, and how each of us can help. He also looks ahead across the next fifteen years to 2030, the United Nations' target date for ending extreme poverty, offering new insights and recommendations.

Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
