Book Notes Flashcards
all the living things and nonliving things around us
environment
the study of how the natural world works, how our environment affects us, and how we affect our environment
environmental science
the various substances and energy sources we take from out environment and that we rely on to survive
natural resources
natural resources replenished over time
renewable natural resources
natural resources that are in finite supply and are formed much more slowly than we use them
nonrenewable natural resources
arise from the normal functioning of natural systems and are not meant for our benefit, yet we could not live without them
ecosystem services
our transition from a hunter-gatherer lifestyle to an agricultural way of life
agricultural revolution
nonrenewable energy sources including oil, coal, and natural gas
fossil fuels
when publicly accessible resources are open to unregulated exploitation, they become overused, and are damaged and depleted
tragedy of the commons
expresses environmental impact in terms of the cumulative area of biologically productive land and water required to provide the resources a person or population consumes and to dispose of and recycle the waste a person or population produces
ecological footprint
borrows techniques from multiple disciplines and brings their research results together in a broad synthesis
interdisciplinary
disciplines that examine the natural world
natural sciences
disciplines that address human interactions and institutions
social sciences
environmental programs that incorporate the social sciences extensively
environmental studies
social movement dedicated to protecting the natural world from undesirable changes brought about by human actions
environmentalism
systematic process for learning about the world and testing our understanding of it
science
research in which scientists gather basic information about organisms, materials, systems, or processes that are not well known and cannot be manipulated in experiments
observational (descriptive) science
research that proceeds in targeted and structured way, using experiments to test hypotheses within the scientific method
hypothesis-driven science
technique for testing ideas with observations
scientific method
statement that attempts to explain a phenomenon or answer a scientific question
hypothesis
specific statements that can be directly tested
predictions
activity designed to test the validity of a prediction or a hypothesis
experiment
conditions that can change
variables
widely accepted, well tested explanation of one or more cause and effect relationships that has been validated by research
theory
dominant view
paradigm
branch of philosophy that involves the study of good and bad
ethics
these people believe that ethics should and do vary with social contexts
relativists
these people maintain that there exist objective notions of right and wrong that hold across cultures and contexts

conservation
fair treatment of all people with respect to environmental policy and practice
environmental justice
living within our planet’s means
sustainability
earth’s accumulated wealth of resources
natural capital
the use of resources in a manner that satisfies our current needs but does not compromise the future resource availability
sustainable development
a population or group of populations whose members share certain traits and can freely breed with one another and produce fertile offspring
species
a group of individuals of a particular species that live in a particular area
population
change over time
evolution
process where inherited characteristics that enhance survival and reproduction are passed on more often to future generations than those that do not
natural selection
a trait that promotes success
adaptation
accidental changes in DNA
mutations
selection conducted under human direction
artificial selection
the variety of life across all levels of biological organization
biological diversity
process by which new species are generated
