Altering the Earth's Chemistry by Sandra Postel Pdf
Human activities that have altered the earth's chemistry are discussed in terms of their potential ecological and economic consequences. Humanity's impact on the disruption of the natural cycles of carbon, nitrogen, and sulfur is assessed. Data are presented which illustrate the extent of change in these cycles. Risks particularly threatening and costly to society are identified as those associated with food, security, forests, and human health. Each of these risk areas are explained and specific problems and conditions are highlighted. Strategies of minimizing risks through measures that remedy several problems simultaneously are advocated. Recommended actions include: (1) reduction of fossil fuel use; (2) support of new energy technologies; (3) establishment of standards for residential appliances; (4) increase of recycling efforts; (5) preservation of forests and planting of trees; (6) elimination of lead in gasoline; (7) more extensive toxicity testing; (8) use of an integrative pest management program; and (9) detoxification of wastes. Because of the global nature of these risks, international co-operation and active collaboration efforts to explore policy options are urged. (ML)
This book provides insight into the basic aspects of ecology that impact or are affected by engineering practices. Ecological principals are described and discussed through the lens of the influences that built structures have on the Earth’s biological, geological, and chemical systems. The text goes on to elucidate the engineering influences that have or will influence the face of the Earth. These influences redesign the Earth, either by destroying natural systems and replacing them with highly subsidized systems or by attempting to restore highly disturbed or contaminated systems with the basic natural systems that were originally present.
The Dynamical Theory of the Formation of the Earth, Based on the Assumption of Its Nonrotation During the Whole Period Called "the Beginning" by Archibald Tucker Ritchie Pdf
These poems record the partly predictable, partly random representative days in a year that inspire wonder at their swiftness. Seasonal time is reflected in the changing angle of sunlight, and familial time is marked by birthdays and holiday celebrations. Public events take on both a sense of history and a sense of unreality in the bright glare of media attention and shiny celebrity surfaces. All the various time-orders in which we live overlay one another: a red leaf adrift in a stream is emblematic of autumn’s recurrence; after years of marriage, a couple’s wedding suddenly seems very close. Spurred by the sensation of accelerating days at the turn of the new millennium, James Applewhite explores the interplay of immediate experience and lasting memory, of continuity and change, over time-that elusive, ineffable, yet crucial medium of self-definition and of understanding the cosmos.
