Together, We Can Make a Difference. Today’s environmental problems may seem too overwhelming for one person to tackle . . . but you don’t have to do it alone. Now you have partners—50 of them. 50 Simple Things, the revolutionary 1990 bestseller, is back in a completely revised, updated edition . . . and it’s just as innovative and groundbreaking as the original. The authors have teamed up with 50 of America’s top environmental groups, including The Natural Resources Defense Council, the National Wildlife Federation, and Rainforest Action Network. Each group has chosen one issue and provided a simple, step-by-step program that will empower you and your family to become citizen activists in the fight to save the Earth. It’s easy to get started. Just pick one!. Fight global warming “one city at a time” with the Sierra Club’s Cool Cities Campaign. Roll up your sleeves and save an endangered species with the Wilderness Society. Protect coral reefs and create a marine reserve with Seacology. Get your congregation excited about protecting God’s creations with Interfaith Power and Light. Invite songbirds into your neighborhood with the National Audubon Society. All it takes is a little effort. When we work together, we can work miracles! Get started now!. John Javna and the Earthworks Group wrote the original 50 Simple Things You Can Do to Save the Earth in 1989. Sophie and Jessie Javna, who were not yet born when the first edition made its debut, are now high school students. They’re excited to be writing their first book, one they hope will benefit people in the generations to come. more...

The book begins with an overview of the research topics which were addressed in the three different phases of the Dutch Priority Program on Acidification (DPPA), executed between 1985 and 1994. This chapter is followed by a chapter which deals with the emissions of acidifying substances, the concentrations and the deposition to forest and nature conservation areas. Prognoses are given for the acid deposition in 2000 and 2010; the deposition in the countries surrounding the Netherlands is also mentioned. The differences in the results of the DPPA-II are analysed. The third chapter deals with the effects of exposure and load on forests. The chapter moves from small-scale to large-scale: first the effects in laboratory-scale studies are described, then the effects in the field, both at stand level and on a regional scale. In addition, the critical thresholds (critical level of concentration and critical load of deposition) are discussed. The fourth chapter covers terrestrial ecosystems (or parts thereof) as well as weakly buffered surface waters, springs and other streams. Critical levels and loads are also discussed. The most important results are given in chapter 5. In the appendices of the book, so-called umbrella theme reports on deposition, stand modelling and effects on forests are presented which describe in more detail the scientific work performed in the third phase of the DPPA. This book will be of interest to anyone involved in research related to acidification and eutrophication; i.e., not only those who perform the research in the causal chain from emissions to effects, but also policy-makers and students. more...
