Study Notes

Environmental Science Key Terms

Environment: The sum of all biotic (living) and abiotic (non-living) factors affecting an organism or ecological system.
Biotic Factor: Any living component of an ecosystem (e.g., plants, animals, bacteria).
Abiotic Factor: Any non-living component of an ecosystem (e.g., sunlight, temperature, water).
Environmental Science: The interdisciplinary study of how humans interact with the environment.
Environmentalism: A social movement aimed at protecting the natural world.
Culture: Collective beliefs, values, and practices influencing human behavior and environment interaction.
Stewardship: Responsible management and care for the environment.
Anthropocentric: A worldview that prioritizes humans as the central element of existence.
Biocentric: A worldview that values all living organisms.
Ecocentric: A worldview that values entire ecosystems, encompassing both living and non-living components.
Utilitarian: Emphasizes the practical and economic benefits of resources.
Preservation: Protecting the environment from human interference.
Conservation: Managing natural resources for long-term sustainability.
Environmental Ethics: 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 characterized by frequent movement in search of resources.
Agricultural Revolution: The shift from nomadic lifestyles to settled farming, increasing resource use.
Industrial Revolution: A period of industrialization greatly increasing energy 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 variables.
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 unaware of group assignments to prevent bias.
Double-Blind Experiment: Participants and researchers 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.
Skepticism: Questioning and critically evaluating scientific claims.
Environmental Justice: Fair distribution of environmental benefits and burdens.

Key Concepts and Explanations

Biotic and Abiotic Factors: Examples of biotic factors in a forest include trees, deer, and fungi; abiotic factors include sunlight, soil, and water.
Goals of Environmental Science vs. Environmentalism: Environmental science uses data and research to understand interactions and solve problems, whereas environmentalism advocates for protecting nature on ethical and moral grounds.
Interdisciplinary Nature of Environmental Science: Combines biology, chemistry, physics, geology, and social sciences to address environmental issues.
Requirements for Life: Organisms require energy (sunlight), nutrients, water, and suitable temperature ranges.
Exxon Valdez Oil Spill: A significant environmental disaster involving an oil tanker spill in 1989.
Scientific Method: Observation, hypothesis formation, experimentation, data analysis, and conclusion.
Variables in Experiments: Independent variable (e.g., fertilizer type), dependent variable (e.g., plant height).
Control and Experiment Types: Control trials (no fertilizer) ensure results are due to the independent variable.
Culture and Worldview: Western cultures may prioritize economic growth, while indigenous cultures may focus on harmony with nature.
Preservation vs. Conservation: Preservation focuses on keeping untouched areas, while conservation emphasizes sustainable resource management.
Tragedy of the Commons: Overuse of shared resources, illustrated by overfishing in the oceans.
Easter Island Case Study: An example of societal collapse due to resource depletion.
Ecological footprint: A measure of human impact on Earth's resources and capacity to absorb waste, determined by consumption.
Science vs. Pseudoscience: Science relies on empirical evidence and peer review; pseudoscience lacks rigorous evaluation.
