    Environmental Science Key Terms

    • Environment: The sum of all biotic (living) and abiotic (non-living) factors that affect an organism or ecological system.
    • Biotic Factor: Any living component of an ecosystem (e.g., plants, animals, bacteria).

    • Environmental Science: The interdisciplinary study of how humans interact with the environment.
    • Environmentalism: A social movement aimed at protecting the natural world.
    • Culture: The collective beliefs, values, and practices that influence human behavior and interaction with the environment.
    • Stewardship: Responsible management and care for the environment.
    • Anthropocentric: A worldview that considers humans as the central and most important element of existence.
    • Biocentric: A worldview that values all living organisms and considers their well-being.
    • Ecocentric: A worldview that values entire ecosystems, including both living and non-living components.
    • Utilitarian: Emphasizes practical and economic benefits of resources.
    • Preservation: Protecting the environment from human interference.
    • Conservation: Managing natural resources to ensure their long-term sustainability.
    • Environmental Ethics: The moral principles guiding human interaction with the environment.
    • Renewable Resource: A resource replenished naturally over short periods (e.g., sunlight, wind).
    • Nonrenewable Resource: A resource that forms slowly and is finite (e.g., fossil fuels, minerals).
    • Nomadic Lifestyle: A way of life where people move frequently in search of food and resources.
    • Agricultural Revolution: The shift from nomadic lifestyles to settled farming, increasing resource use.
    • Industrial Revolution: A period of industrialization that greatly increased energy use and resource demand.
    • Consumption: The use of goods and resources by individuals or societies.
    • Ecological Footprint: A measure of human demand on Earth's ecosystems.
    • Independent Variable: The variable manipulated in an experiment.
    • Dependent Variable: The variable measured in an experiment.
    • Qualitative Data: Non-numerical data describing qualities or characteristics.
    • Quantitative Data: Numerical data describing quantities or measurements.
    • Manipulative Experiment: An experiment where the researcher actively changes the independent variable.
    • Controlled Experiment: An experiment with a control group and experimental group(s) to isolate variable effects.
    • Control: A baseline in an experiment used for comparison.
    • Natural Experiment: Observation of natural events without manipulation by researchers.
    • Laboratory Experiment: Experiments conducted in a controlled indoor environment.
    • Field Experiment: Experiments conducted in natural settings.
    • Blind Experiment: Participants do not know which group they are in to prevent bias.
    • Double-Blind Experiment: Both researchers and participants are unaware of group assignments to eliminate bias.
    • Experimental Bias: When researchers' expectations influence results.
    • Correlation: A relationship between two variables that does not imply causation.
    • Model: A simplified representation of a system or phenomenon.
    • Peer Review: Evaluation of scientific work by other experts in the field.
    • Skepticism: Questioning and critically evaluating scientific claims.
    • Environmental Justice: The fair distribution of environmental benefits and burdens.
