Evir. Science Exam #1 Flashcards
Environmental Literacy
a basic understanding of how ecosystems function and of the impact of our choices on the environment (ability to understand environmental problems)
Environmentalism
a broad philosophy, ideology and social movement regarding concerns for environmental conservation and improvement of the health of the environment, seeks to incorporate the concerns of non-human elements
Ecocentric Worldview
System Centered: value is given to the importance of the ecosystem as a whole, including interactions between species as well as natural processes
If the ice caps melt in Greenland and Antarctica the water level would rise
70 meters
What is Environmental Science?
the study of the intersection of human society and the natural world
Wicked Problems
large, complex social problems where there is no clear solution
People, planet, and profit need to be looked at for
sustainability
How we view the would and our existence is influenced by
cultural, religious, and personal experiences
Anthropocentric Worldview
Human-centered: only humans have intrinsic value and resources are here to meet human needs and wants
Biocentric Worldview
Life Centered: Humans and other species have a right to exist and are worthy of protection equal to all other species (all species are equal)

Anthropocene
a new geologic epoch marked by human impact
4 Characteristics of a Sustainable Ecosystem
rely on renewable energy, recycle matter, have population control, depend on local biodiversity
What epoch do we live in?
Holocene Epoch which began 12,000 years ago
Which characteristic of sustainable ecosystems is the most important?
Depending on the local biodiversity
Population Control is kept in check by
predators, disease, and competition
Social Traps
Decisions produce short-term benefits, but hurt society in the long run
Social trap Example
Tragedy of the Commons: each person acts in a way to maximize his/her own benfit
Ways to stop social traps are?
education, privatization, and regulation
Science is NOT
subjective, ethical, or spiritual questions
Observation
information gathered with our senses or equipment that extends our senses
Inference
conclusions drawn based on those obersvations
Scientific Method is used to
propose hypotheses, systematically test predictions, base conclusions on evidence
Steps of the Scientific Method
make observations, form hypothesis, and share information
Hypothesis
a possible explantation fo an observation based on previous knowledge
Experimental Prediction
a statement that identifies what is expected to happen if the hypothesis being tested is correct
Hypothesis must be
testable and falsifiable
Hypotheses can NEVER
be proven correct
Theory
a widely accepted explanation for a natural phenomenon that has been extensively and rigorously scientifically tested
