DOWNLOAD EBOOKThe Cold War Era left the major participants, the United States and the former Soviet Union (FSU), with large legacies in terms of both contamination and potential accidents. Facility contamination and environmental degradation, as well as the accident vulnerable facilities and equipment, are a result of weapons development, testing, and production. Although the countries face similar issues from similar activities, important differences in waste management practices make the potential environmental and health risks of more immediate concern in the FSU and Eastern Europe. In the West, most nuclear and chemical waste is stored in known contained locations, while in the East, much of the equivalent material is unconfined, contaminating the environment. In the past decade, the U.S. started to address and remediate these Cold War legacies. Costs have been very high, and the projected cost estimates for total cleanup are still increasing. Currently in Russia, the resources for starting such major activities continue to be unavailable.

DOWNLOAD EBOOKMike Hudak traveled throughout the West speaking with former employees of wildlife and land management agencies, and citizens who have long advocated for better management of our public lands. Western Turf Wars is a compliation of these accounts - testimonies that reveal how and why the management agencies have failed to protect our public lands. Underlying that management failure is the cowboy myth's social and political legacies.

DOWNLOAD EBOOKMany fish species, like salmon and sturgeon, undertake extended migrations as part of their basic behavior, and other fish and invertebrates also undertake short-term or small-scale migrations at certain phases of their life cycles. Activities such as dam construction for water supply and power generation, channelization for navigation and flood control, land drainage and wetland reclamation for agricultural and urban use all have profound impact on the aquatic ecosystem and thus on natural fish populations. Fish passes are often the only way to make it possible for aquatic fauna to pass obstacles that block their up-river journey. Based on knowledge and experience from mainly Europe and North America, this book describes the various types of fish passes, with special emphasis to "close-to-nature" solutions.
