Chapter 1: Environmental Problems, Their Causes, and Sustainability Flashcards
is a study of connections in nature
Environmental Science
- is everything around us
- it includes all of the living and non-living things with which we interact
The Environment
an interdisciplinary study of how humans interact with the environment of living and non-living things
Environmental Science
5 Major Fields of Study Related to Environmental Science
- Biology
- Chemistry
- Earth Science
- Social Sciences
- Humanities
study of living things (organisms)
Biology
study of chemicals and their interactions
Chemistry
study of the planet as a whole and its nonliving systems
Earth Science
studies of human society
Social Sciences
study of the aspects of the human condition not covered by the physical and social sciences
Humanities

study of how organisms interact with one another and with their nonliving environment
Ecology
study of plants
Botany
study of animals
Zoology
study of the chemistry of living things
Biochemistry
study of the earth’s atmosphere and climate
Climatology
study of the earth’s origin, history, surface, and interior processes
Geology
study of the earth’s water resources
Hydrology
study of fossils and ancient life
Paleontology
study of human cultures
Anthropology
study of the characteristics of human populations
Demography
study of the relationships between human populations and the earth’s surface features
Geography
study of the production, distribution, and consumption of foods and services
Economics
study of the principles, processes, and structure of government and political institutions
Political Science
study of information and ideas about humanity’s past
History
study of moral values and concepts concerning right and wrong human behavior and responsibilities
Ethics
study of knowledge and wisdom about the nature of reality, values, and human conduct
Philosophy
- a key subfield of environmental science
- biological science that studies how organisms, or living things, interact with their environment and with each other
Ecology
a group of organisms with distinctive traits and, for sexually reproducing organisms, can mate and produce fertile offspring
Species
major focus of ecology
Study of Ecosystems
is a set of organisms interacting with one another and with their environment of nonliving matter and energy within a defined area or volume
Ecosystem
- a social movement dedicated to protecting the earth’s life-support systems for us and all other forms of life
- is practiced more in the political and ethical arenas than in the realm of science
Environmentalism
Three Principles of Sustainability
- Life depends on solar energy
- Biodiversity provides natural services
- Chemical/nutrient cycling means that there is little waste in nature
- is the ability of the earth’s various natural systems and human cultural systems to survive and adapt to changing environmental conditions indefinitely
- means meeting our own needs without compromising the ability of future generations to meet their own needs
Sustainability
7 Key Components of Sustainability
- Life depends on natural capital, natural resources, and natural services
- Many human activities can degrade natural capital
- Solutions are being found and implemented
- Sustainability begins at personal and local events
- Natural Capital
- Natural Resources
- Natural Services
the natural resources and natural services that keep us and other forms of life alive and support our human economies
Natural Capital
are materials and energy in nature that are essential or useful to humans
Natural Resources
natural resources are often classified as _____ (such as air, water, soil, plants, and wind) or _____ (such as copper, oil, and coal)
renewable resources; nonrenewable resources
are processes in nature, such as purification of air and water and renewal of topsoil, which support life and human economies
Natural Services
Equation for Natural Capital
Natural Capital = Natural Resources + Natural Services
supported by energy from the sun - another of the _____
Natural Capital; principles of sustainability
Without it, natural capital and the life it supports would collapse
Solar Energy
- one vital natural service
- the circulation of chemicals necessary for life, from the environment (mostly from soil and water) through organisms and back to the environment
Nutrient Cycling
- an important component
- the upper layer of any soil in which plants can grow
- it provides the nutrients that support plants, animals, and microorganisms living on land
Topsoil
it is the basis for one of the three principles of sustainability that if without it, life as we know it could not exist
Nutrient cycling in topsoil
