Despite the benefits of advanced technology and modern safety mechanisms, the world around us seems to grow ever more dangerous and fraught with hidden risks. Even in the information age, it is challenging to discern factual, scientific information from sensationalized accounts in the media, "e;urban legends,"e; or unsubstantiated Internet lore.In 50 Health Scares That Fizzled, award-winning author and researcher Joan R. Callahan examines 50 health scares in 7 distinct categories: medical interventions, infectious diseases, food scares, additives in foods or beverages, other biological hazards, chemical or radiological exposures, and lifestyle choices. With great wit and a light tone, Dr. Callahan alleviates readers' concerns and deftly explains the complex issues, making the subject matter approachable.

The changes and significant developments that have accompanied the relatively young field of environmental science are documented in this addition to the Oryx Frontiers of Science Series. From major causes for environmental concern to possible solutions, Environmental Science presents a balanced and comprehensive view of the collective fields of ecology, sociology, demography, and waste management. Special focus is on important environmental events and discoveries that occurred between 1996 and 1999. Additionally, related information is presented on key people, career opportunities, organizations, resources, and more. This is a must-have reference tool for understanding a larger view of environmental science.
