This book analyses the state of the natural environment and the causes of its degradation using the biosphere approach. Further, those issues that must be resolved immediately on the global level are identified following the ideas defined by V.I. Vernadsky, and new principles of Man-Nature interaction are pursued. The modern world currently faces three global trends inducing biosphere degradation and the aggravation of ecological hazards, namely: a) rapid and uncontrolled growth of human population on the Earth and insufficient natural resources to sustain it; (b) technogenesis development; and (c) global climate change and the aggravation of natural disasters. Ecological safety and military security are becoming the crucial conditions for the survival of modern civilization. To mitigate the ecological strain on the Earth, the technogenesis strategy should be changed and many other pressing issues must be resolved. These problems should be addressed using the biosphere approach, because the individual human being is the biosphere constituent, and his or her safety cannot be provided without maintaining the entire natural system on our planet.

A concrete program for safeguarding the atmosphere.

This book provides an introduction to general ecology, life safety and environment protection. It reviews the current problems resulting from anthropogenic changes of the environment, discusses the ways and methods of reducing the negative sub-sequences, regards various aspects of biosphere preservation, the concept and the principles of forming environmental ideology and organising rational nature management.

This study, commissioned by the National Aeronautics and Space Administration (NASA), examines the role of robotic exploration missions in assessing the risks to the first human missions to Mars. Only those hazards arising from exposure to environmental, chemical, and biological agents on the planet are assessed. To ensure that it was including all previously identified hazards in its study, the Committee on Precursor Measurements Necessary to Support Human Operations on the Surface of Mars referred to the most recent report from NASA's Mars Exploration Program/ Payload Analysis Group (MEPAG) (Greeley, 2001). The committee concluded that the requirements identified in the present NRC report are indeed the only ones essential for NASA to pursue in order to mitigate potential hazards to the first human missions to Mars.

The Biosphere, Problems and Solutions

"Vladimir Vernadsky was a brilliant and prescient scholar-a true scientific visionary who saw the deep connections between life on Earth and the rest of the planet and understood the profound implications for life as a cosmic phenomenon." -DAVID H. GRINSPOON, AUTHOR OF VENUS REVEALED "The Biosphere should be required reading for all entry level students in earth and planetary sciences." -ERIC D.

The purpose of this regional workshop in the Southeast was to broaden the environmental health perspective from its typical focus on environmental toxicology to a view that included the impact of the natural, built, and social environments on human health. Early in the planning, Roundtable members realized that the process of engaging speakers and developing an agenda for the workshop would be nearly as instructive as the workshop itself. In their efforts to encourage a wide scope of participation, Roundtable members sought input from individuals from a broad range of diverse fields-urban planners, transportation engineers, landscape architects, developers, clergy, local elected officials, heads of industry, and others. This workshop summary captures the discussions that occurred during the two-day meeting. During this workshop, four main themes were explored: (1) environmental and individual health are intrinsically intertwined; (2) traditional methods of ensuring environmental health protection, such as regulations, should be balanced by more cooperative approaches to problem solving; (3) environmental health efforts should be holistic and interdisciplinary; and (4) technological advances, along with coordinated action across educational, business, social, and political spheres, offer great hope for protecting environmental health. This workshop report is an informational document that provides a summary of the regional meeting.
