"Betsy Mix Cowles--a bold reformer whose circle of acquaintances included Frederick Douglass, Abby Kelley, and William Lloyd Garrison--is a brilliant example of what an educated and independent woman can accomplish. A staunch defender of abolitionism, Cowles also took up the cause of women's rights and dedicated her life to the advocacy of women's access to education, equal rights, and independence in the pre-Civil War era. The life of this devoted social reformer illuminates the struggles and historical developments relating to abolitionism and the fledgling women's movement during one of the most contentious periods in American history. About the Lives of American Women series: Selected and edited by renowned women's historian Carol Berkin, these brief biographies are designed for use in undergraduate courses. Rather than a comprehensive approach, each biography focuses instead on a particular aspect of a women's life that is emblematic of her time, or which made her a pivotal figure in the era. The emphasis is on a "good read," featuring accessible writing and compelling narratives, without sacrificing sound scholarship and academic integrity. Primary sources at the end of each biography reveal the subject's perspective in her own words. Study questions and an annotated bibliography support the student reader"--

Since the discovery of fire, humans have been energy users. And this is a good thing--our mastery of energy is what separates us from the rest of the animal kingdom and has allowed us to be the dominant species on the planet. However, this mastery comes with a price: we are changing our environment in a profoundly negative way by heating it up. Using one engaging story after another, coupled with accessible scientific facts, world authority Richard B. Alley explores the history of energy use by humans over the centuries, gives a doubt-destroying proof that already-high levels of carbon dioxide are causing damaging global warming, and surveys the alternative energy options that are available to exploit right now. These new energy sources might well be the engines for economic growth in the twenty-first century.--From publisher description.

Synopsis: Green Technology is an eight-volume set that examines the relationship between human activities and their sometimes harmful consequences for the environment and explores new methods of repairing and restoring the Earth. Approaching environmental issues confronting society from a technological perspective has spawned significant controversy, and the books in this set present all sides of the debate. Designed to complement science curricula, the set also covers relevant history and new green technologies and innovations that will contribute to the field in the future. Renewable Energy: Sources and Methods examines the current technologies in renewable energy, a critical subject given that the world increases its energy consumption between 1 and 3 percent each year. Considering the current rate of energy consumption and the consequences of continuing at this rate, the book explains how the main conventional sources of energy-including coal, oil, and gas-affect economies worldwide. The book also focuses on the remarkable diversity of ideas and innovations in the field of alternative energy. Sidebars, figures, and case studies enhance fundamental concepts and examine urgent issues related to the future of the environment. The volume includes information on: alternative vehicles; biomass; the biorefining industry; "clean" energy; converting solid waste to energy; Earth's energy sources; green building design and construction; recycling; water conservation; and worldwide energy programs. The book contains more than 40 color photographs and line illustrations, five appendixes, a glossary, a detailed list of print and Internet resources, and an index. Green Technology is essential for general readers who seek information on the important issues that affect the environment worldwide.
