Scientific aspects (and many non-scientific aspects) of environmental protection, natural heritage conservation, sustainable living, environmental impact of technologies, and global environmental change. Environmental Science involves the focused application of many other fields of science and engineering, and therefore is related to Biology, Earth Sciences, Chemistry, Physics, Engineering, and the Social Sciences. All resources are organized in subcategories of Science:Environment. For general environmental science topics, start with Directories, Organizations or Journals. For environmental consulting and other products and services see individual topic listing or Products and Services

Biodiversity is not easily defined. Try What is Biodiversity? and Defining The 'B' Word for approaches with differing emphases. Below is a definition adapted from the World Resources Institute, World Conservation Union, and United Nations Environment Programme in Global Biodiversity Strategy 1992.

"Biodiversity is the totality of genes, species, and ecosystems in a region... Biodiversity can be divided into three hierarchical categories -- genes, species, and ecosystems -- that describe quite different aspects of living systems and that scientists measure in different ways.

Genetic diversity refers to the variation of genes within species. This covers distinct populations of the same species (such as the thousands of traditional rice varieties in India) or genetic variation within a populations (high among Indian rhinos, and very low among cheetahs) ...

Species diversity refers to the variety of species within a region. Such diversity can be measured in many ways, and scientists have not settled on a single best method. The number of species in a region -- its species richness -- is one often- used measure, but a more precise measurement, taxonomic diversity, also considers the relationship of species to each other. For example, an island with two species of birds and one species of lizard has a greater taxonomic diversity than an island with three species of birds but no lizards ...

Ecosystem diversity is harder to measure than species or genetic diversity because the boundaries of communities -- associations of species -- and ecosystems are elusive. Nevertheless, as long as a consistent set of criteria is used to define communities and ecosystems, their numbers and distribution can be measured ..."

Resources related to biodiversity or conservation as an issue or a topic of debate belong primarily in the relevant subcategory of Society/Issues/Environment.

Environmental Health - Definition. Environmental health comprises those aspects of human health, including quality of life, that are determined by interactions with physical, chemical, biological and social factors in the environment. It also refers to the theory and practice of assessing, correcting, controlling and preventing those factors in the environment that may adversely affect the health of present and future generations.

Simply stated, impact assessment is identification of future consequences of a current or proposed action. Environmental impact assessment is currently required by laws in many nations of the world. Environmental impact assessment is an intensely interdisciplinary process that utilizes the biological, physical, and social sciences in analyzing the potential impacts of an action and in devising strategies for minimizing or preventing such impacts. Closely related fields that are also covered in this category include life cycle analysis of products and social impact assessment.

The World Commission on Environment and Development (the Brundtland Commission), defined "sustainable development" as follows in the report Our Common Future (Oxford : Oxford University Press, 1987): "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts: the concept of "needs", in particular the essential needs of the world's poor, to which overriding priority should be given; and the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs." Sustainability can encompass many things and can be pursued on several different levels and scales. This section of the Open Directory addresses global-scale sustainability, regional and community sustainability, and sustainable living in daily lives. ("Think globally, act locally.")
