Chapter 1 Vocab Flashcards
affluence
Wealth that results in high levels of consumption and unnecessary waste of resources, based mostly on the assumption that buying more and more material goods will bring fulfillment and happiness.
biodiversity
Variety of different species (species diversity), genetic variability among individuals within each species (genetic diversity), variety of ecosystems (ecological diversity), and functions such as energy flow and matter cycling needed for the survival of species and biological communities (functional diversity).
chemical cycling
The continual cycling of chemicals necessary for life through natural processes such as the water cycle and feeding interactions; processes that evolved due to the fact that the earth gets essentially no new inputs of these chemicals.
doubling time
Time it takes (usually in years) for the quantity of something growing exponentially to double. It can be calculated by dividing the annual percentage growth rate into 70.
ecological footprint
Amount of biologically productive land and water needed to supply a population with the renewable resources it uses and to absorb or dispose of the wastes from such resource use. It is a measure of the average environmental impact of populations in different countries and areas. See per capita ecological footprint.
ecology
Biological science that studies the relationships between living organisms and their environment; study of the structure and functions of nature.
ecosystem
One or more communities of different species interacting with one another and with the chemical and physical factors making up their nonliving environment.
ecosystem services
Natural services or natural capital that support life on the earth and are essential to the quality of human life and the functioning of the world’s economies. Examples are the chemical cycles, natural pest control, and natural purification of air and water. See natural resources.
environment
All external conditions, factors, matter, and energy, living and nonliving, that affect any living organism or other specified system.
environmental degradation
Depletion or destruction of a potentially renewable resource such as soil, grassland, forest, or wildlife that is used faster than it is naturally replenished. If such use continues, the resource becomes nonrenewable (on a human time scale) or nonexistent (extinct). See also sustainable yield.
environmental ethics
Human beliefs about what is right or wrong with how we treat the environment.
environmental science
Interdisciplinary study that uses information and ideas from the physical sciences (such as biology, chemistry, and geology) with those from the social sciences and humanities (such as economics, politics, and ethics) to learn how nature works, how we interact with the environment, and how we can to help deal with environmental problems.
environmental wisdom worldview
Worldview holding that humans are part of and totally dependent on nature and that nature exists for all species, not just for us. Our success depends on learning how the earth sustains itself and integrating such environmental wisdom into the ways we think and act. Compare frontier worldview, planetary management worldview, stewardship worldview.
environmental worldview
Set of assumptions and beliefs about how people think the world works, what they think their role in the world should be, and what they believe is right and wrong environmental behavior (environmental ethics). See environmental wisdom worldview, frontier worldview, planetary management worldview, stewardship worldview.
exhaustible resource
Resource that exists in a fixed amount (stock) in the earth’s crust and has the potential for renewal by geological, physical, and chemical processes taking place over hundreds of millions to billions of years. Examples include copper, aluminum, coal, and oil. We classify these resources as exhaustible because we are extracting and using them at a much faster rate than they are formed. Compare renewable resource. See nonrenewable resource.
exponential growth
Growth in which some quantity, such as population size or economic output, increases at a constant rate per unit of time. An example is the growth sequence 2, 4, 8, 16, 32, 64, and so on, which increases by 100% at each interval. When the increase in quantity over time is plotted, this type of growth yields a curve shaped like the letter J. Compare linear growth.
full-cost pricing
Finding ways to include the harmful environmental and health costs of producing and using goods in their market prices. See external cost, internal cost.
hunter gatherers
People who get their food by gathering edible wild plants and other materials and by hunting wild animals and catching fish.
inexhaustible resource
Essentially inexhaustible resource on a human time scale because it is renewed continuously. Solar energy is an example. Compare nonrenewable resource, renewable resource. See perpetual resource. Compare nonrenewable resource, renewable resource.
input pollution control
Device, process, or strategy used to prevent a potential pollutant from forming or entering the environment or to sharply reduce the amount entering the environment. Compare pollution cleanup. See pollution prevention.
less-developed country
Country that has low to moderate industrialization and low to moderate per capita GDP. Most are located in Africa, Asia, and Latin America. Compare more-developed country.
malnutrition
Faulty nutrition, caused by a diet that does not supply an individual with enough protein, essential fats, vitamins, minerals, and other nutrients needed for good health. Compare overnutrition, chronic undernutrition. See chronic malnutrition.
