Our primary focus here is on these questions where partial or incomplete orderings are directly informative to conservation, remediation, or allocation issues of environmental management. Biodiversity and ecosystem health are multifaceted concerns that are most readily and objectively approached through suites of indicators. Prioritization of landscape units in these regards is also intrinsically complex. If a subset of indicators is essentially concordant across all cases of observation, then the indicators in the (sub)set are also substantially redundant. On the other hand, indicators representing largely independent dimensions of biodiversity or ecosystem health will almost necessarily complicate prioritization processes because there will be less consistency in how the respective landscape units reflect...

From this analysis it is clear that in addition to their benefits, the use of pesticides in food production not only causes serious public health problems but also considerable damage to vital agricultural and natural ecosystems in the United States and world. A conservative estimate suggests that the environmental and social costs of pesticide use in the United States total about 4 billion each year. Worldwide the yearly environmental and public health costs are probably at least 100 billion. This is several times the 18 bllllon/yr spent on pesticides in the world. 

A major amendment was made to the Japanese Chemical Substances Control Law in April 2004 on the recommendations made by the Organization for Economic Co-operation and Development (OECD) in the Environmental Conservation Review - Further Expansion of the Regulation Scope for Conservation of Ecosystem in line with the Agenda 21 - Human Action Program for Sustainable Development of the United Nations Conference on Environment and Development (UNCED). In order to conform to international harmonisation, the amended Chemical Substances Control Law has introduced a new examination and regulation system to prevent not only hazards to human health but also damages to animals and plants.

Water is abundant in the Amazon, and nearly all living things in the basin are somehow dependent on this abundance. From the standpoint of development and conservation, the most crucial issue in water management is water quality. Clean water is fundamental to the maintenance of the Amazon s unique aquatic ecosystems and to the health of its people, who rely on surface water to satisfy their household water needs and to provide fish and other aquatic plants and organisms for their nutritional needs. Water quality is intricately linked to biogeochemical reactions such as the dissolution and decomposition of... 

Conserve and improve natural ecosystems while protecting human health and well-being. 

Natural ecosystems should be conserved and improved v hile protecting human health and well-being. Life-cycle thinking should be used in all engineering activities. 

States shall cooperate in a spirit of global partnership to conserve, protect and restore the health and integrity of the Earth s ecosystem. In view of the different contributions to global environmental degradation, States have common but differentiated responsibilities. The developed countries acknowledge the responsibility they bear in the international pursuit of sustainable development in view of the pressures their societies place on the global environment and of the technologies and financial resources they command.
