a social movement that works toward equal enforcement of environmental laws in poor communities.
A good example of direct human manipulation of the natural environment is seen in
adding emissions to the atmosphere from driving cars and converting land from forest to growing crops.
Natural experiments lack
an exact replication of the experiment.
The health of frog populations is used as an indicator of environmental health because frogs
are amphibious.
Ecosystem services
are the processes by which life supporting resources are produced, can be provided by a forest, can be provided by an aquifer, and can be provided by soil.
Sustainable development
balances human needs and economic development.
Factors that are responsible for grain production not keeping up with worldwide population include
crop diseases, soil degradation, use of food crops for fuel, and government encouragement to let land remain uncultivated.
The effect of a Pfiesteria outbreak on humans is a
decrease in tourism, economic loss from decreased seafood sales, decrease in recreational fishing, and increase of skin sores and nausea.
Environmental indicators
do not always describe what is causing a change in the environment.
Environmental Studies cover
ethics, policy, literature, and economics.
Evidence of biodiversity is seen in the
genetic variation among human populations, number of species in a region, number of ecosystems and habitats in a region, and variety of nutrients available in a region.
The population with the greatest ability to respond to environmental change most likely is the one with
high genetic diversity.
Precision is
how close a measured value is to repeated measurements of the same sample.
Accuracy is
how close a measured value is to the actual value.
Economic development goes hand in hand with
increased consumption of resources.
The study of environmental science differs from study of the natural sciences such as biology and chemistry because it
involves politics, law, and economics.
Dissemination of scientific results
is an essential part of the scientific process, allows for scientists to discuss results, furthers critical thinking, and assists researchers in developing alternative explanations to observable phenomena.
The concentration of carbon dioxide in the atmosphere
is increasing in part due to fossil fuel use and is increasing in part due to deforestation.
Deductive reasoning
is the process of making general statements from specific facts and is the process of applying a general statement to specific facts.
Inductive reasoning
is the process of making general statements from specific facts.
Controlled experiments in nature are difficult because
large amounts of land are sometimes required to produce natural conditions.
Pfiesteria is a
microscopic free living organism
Natural experiments can be done when a
natural event changes an ecosystem, volcanic eruption destroys a forest, fire sweeps through a prairie, and tornado uproots a section of a forest.
A phenomenon that has been rigorously tested and to whic there are no known exceptions is called a(n)
natural law.
New innovations in food production are
not keeping pace with food needs of the world and frequently the cause of soil degradation.
The factor that enabled Pfiesteria to enter the life stage that caused fish kills in the Neuse River of North Carolina is that
nutrients were added to the water.
Greenhouse gases in the atmosphere are
responsible for constant temperatures near Earth's surface.
Living in an environmentally sustainable way necessitates
sensitivity to the needs of future generations.
The comparison between the rate of speciation and background extinction rate is that
speciation and background extinction rate are very slow, natural processes and environmental stress may cause species to go extinct faster than new ones can evolve.
A hypothesis is different from a belief because it is
