Available in PDF, EPUB and Kindle. Book excerpt: Our planet is under siege. Assaults on the atmosphere -the greenhouse effect, the depletion of the ozone layer and increasing air pollution - pose a still unquantified threat to human life. The dumping of hazardous wastes, and land based sources of pollution, present a similar threat to the oceans. On land we are destroying a tropical forest the size of Austria every year, and more than a hundred species of wild plants and animals are lost forever each day. When the General Assembly of the United Nations established UNEP it charged us with reporting on the changing state of the world's environment, tracking the underlying causes of change, and working with governments to develop responses to those changes. Every year since 1974, UNEP has produced a State of the Environment report, focusing on one or more emerging environmental issues and always stressing the human factor -the impact of environmental quality on people and society. Three times since its inception (1982, 198 7 and 1992) UNEP has undertaken a more wide-ranging study. The results of the present study are the most disturbing of the three. However, not all the signs are negative. Throughout the 19 70s and into the 1980s, UNEP was able to report progress in some important areas. Environmental monitoring capacity was being rapidly improved in many parts of the world, and Ministries of the Environment were being set up in an attempt to deal with environmental threats in a more coherent way.

This book was released on 2003-08-08 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the Office of Space Science of the National Aeronautics and Space Administration (NASA) special importance is attached to exploration of the planet Mars, because it is the most like Earth of the planets in the solar system and the place where the first detection of extraterrestrial life seems most likely to be made. The failures in 1999 of two NASA missions-Mars Climate Orbiter and Mars Polar Lander-caused the space agency's program of Mars exploration to be systematically rethought, both technologically and scientifically. A new Mars Exploration Program plan (summarized in Appendix A) was announced in October 2000. The Committee on Planetary and Lunar Exploration (COMPLEX), a standing committee of the Space Studies Board of the National Research Council, was asked to examine the scientific content of this new program. This goals of this report are the following: -Review the state of knowledge of the planet Mars, with special emphasis on findings of the most recent Mars missions and related research activities; -Review the most important Mars research opportunities in the immediate future; -Review scientific priorities for the exploration of Mars identified by COMPLEX (and other scientific advisory groups) and their motivation, and consider the degree to which recent discoveries suggest a reordering of priorities; and -Assess the congruence between NASA's evolving Mars Exploration Program plan and these recommended priorities, and suggest any adjustments that might be warranted.
