The effects of herbs on the human body are set in a lucid and modern context. Simon Mills describes traditional herbal pathology and therapeutics, and also suggests up-to-date research methods to validate herbalism so that it can take its rightful place among the medical sciences. For practising herbalist and lay reader alike, the detailed pharmacology, based on the author's own extensive research and experience, will be of crucial interest: the active constituents of.

The 32 papers in this volume examine the mode and nature of igneous, metamorphic, tectonic, sedimentological, and biological processes associated with the evolution of oceanic crust in different tectonic settings in Earth history as revealed in various ophiolites and ophiolite belts around the world, and the geodynamic significance of these ophiolites in the evolution of different orogenic systems. Divided into six thematic sections, the book presents a wealth of new data and syntheses from mainly Phanerozoic ophiolites around the world.

"I tell you, God could care less about the poor. Tell me, why must we live here like this? What have we done to deserve this? You're so good and yet you suffer so much," a young boy tells his mother in Tomas Rivera's classic novel about the migrant worker experience. Outside the chicken coop that is their home, his father wails in pain from the unbearable cramps brought on by sunstroke after working in the hot fields. The young boy can't understand his parents' faith in a god that would impose such horrible suffering, poverty and injustice on innocent people. Adapted into the award-winning film ]€]and the earth did not swallow him and recipient of the first award for Chicano literature, the Premio Quinto Sol, in 1970, Rivera's masterpiece recounts the experiences of a Mexican-American community through the eyes of a young boy. Forced to leave their home in search of work, the migrants are exploited by farmers, shopkeepers, even other Mexican Americans, and the boy must forge his identity in the face of exploitation, death and disease, constant moving and conflicts with school officials. In this new edition of a powerful novel comprised of short vignettes, Rivera writes hauntingly about alienation, love and betrayal, man and nature, death and resurrection and the search for community.

Cartographers have long grappled with the impossibility of portraying the earth in two dimensions. To solve this problem, mapmakers have created map projections. This work discusses and illustrates the known map projections from before 500BC to the present, with facts on their origins and use.

Explores ecological disasters and the role of scientists and the public in reversing environmental damage

Mexican Americans have traditionally had a strong land ethic, believing that humans must respect la tierra because it is the source of la vida. As modern market forces exploit the earth, communities struggle to control their own ecological futures, and several studies have recorded that Mexican Americans are more impacted by environmental injustices than are other national-origin groups. In our countryside, agricultural workers are poisoned by pesticides, while farmers have lost ancestral lands to expropriation. And in our polluted inner cities, toxic wastes sicken children in their very playgrounds and homes. This book addresses the struggle for environmental justice, grassroots democracy, and a sustainable society from a variety of Mexican American perspectives. It draws on the ideas and experiences of people from all walks of life—activists, farmworkers, union organizers, land managers, educators, and many others—who provide a clear overview of the most critical ecological issues facing Mexican-origin people today. The text is organized to first provide a general introduction to ecology, from both scientific and political perspectives. It then presents an environmental history for Mexican-origin people on both sides of the border, showing that the ecologically sustainable Norteño land use practices were eroded by the conquest of El Norte by the United States. It finally offers a critique of the principal schools of American environmentalism and introduces the organizations and struggles of Mexican Americans in contemporary ecological politics. Devon Peña contrasts tenets of radical environmentalism with the ecological beliefs and grassroots struggles of Mexican-origin people, then shows how contemporary environmental justice struggles in Mexican American communities have challenged dominant concepts of environmentalism. Mexican Americans and the Environment is a didactically sound text that introduces students to the conceptual vocabularies of ecology, culture, history, and politics as it tells how competing ideas about nature have helped shape land use and environmental policies. By demonstrating that any consideration of environmental ethics is incomplete without taking into account the experiences of Mexican Americans, it clearly shows students that ecology is more than nature study but embraces social issues of critical importance to their own lives.
