Chapter 1: An Introduction to Environmental Science
Learning Objectives
LO 1-1 Define the term environment and understand how people differ in their perceptions of the
environment and environmental problems.
LO 1-2 Explain how environmental scientists use the scientific method and employ different
types of experimental designs to study the environment.
LO 1-3 Characterize the interdisciplinary nature of environmental science.
LO 1-4 Understand some of the root causes of current environmental issues.
LO 1-5 Articulate the concepts of sustainability and sustainable development.
Chapter Overview
Chapter 1 introduces environmental science by defining the environment as more than “nature,”
including biotic and abiotic components, the built environment, and the social, economic, political,
and ethical systems that shape human–environment relationships. The chapter uses images of
Earth from space to show how perspectives can shift, and it explains how worldviews (including
Indigenous perspectives, ecocentrism, biocentrism, and anthropocentrism) influence decisions
and conflicts among environmental stakeholders. It then explains environmental science as
systems-focused and distinct from environmentalism, outlining the scientific method, hypothesis
testing, and common experimental designs. The chapter emphasizes environmental science as
interdisciplinary and introduces Two-Eyed Seeing as a respectful approach that values both
Indigenous knowledge and Western science. Finally, it surveys key drivers and concepts—IPAT,
carrying capacity, ecological footprints, and sustainability—alongside major global challenges and
solutions.
Teaching Notes
Central Case: Earth from Space—The Power of an Image
• Use the case to show how evidence and perspective can change public understanding (e.g.,
whole-Earth photographs and environmental awareness).
• Highlight the idea that map orientation (e.g., “north up”) is a convention, not a natural rule—
connect to worldview and assumptions.
, Chapter 1: An Introduction to Environmental Science Page 2 of 15
• Invite learners to consider how a single compelling representation (photo, graph, map) can
shape policy priorities and public action.
Our Island, Earth (LO 1-1)
• Environment as “sum total of our surroundings”: biotic + abiotic components, plus built
environment, plus social/economic/political/ethical institutions.
• Humans are within the environment: caution against “people vs. nature” framing;
emphasize interconnectedness.
• Legal and governance relevance: environment includes legal, social, and economic
aspects; role of Environment and Climate Change Canada includes protection,
conservation, and forecasting.
• Ecosystem services and natural capital: distinguish goods (tangible) from services
(processes); note the difficulty of assigning monetary value to services.
• Worldviews and justice concepts: introduce environmental stakeholders; environmental
rights (e.g., Ontario Environmental Bill of Rights, 1993); environmental justice and
environmental racism as linked ideas.
The Nature of Environmental Science (LO 1-2)
• Systems thinking: environmental science focuses on interconnected systems and human
pressures on those systems.
• Environmental science vs. environmentalism/activism: clarify differences while noting
overlap in motivations.
• Scientific method steps: observation → question → hypothesis → predictions (null and
alternate) → test → analyze/interpret.
• Hypotheses must be testable and falsifiable: use the algae/fertilizer example to show
how a hypothesis becomes testable.
• Scientific community process: peer review, publishing, conflicts of interest, and evolving
scientific consensus; define “theory” in scientific terms.
Types of Experimental Designs (Box 1.1)
• Controlled experiments: isolate the independent variable; control vs treatment;
importance of replication; “proof of concept.”
• Manipulative experiments: more realistic systems (mesocosms/whole-ecosystem work);
include ethics and approval.
• Mensurative/correlational studies: measure variation without manipulation; causality is
harder to infer; useful where manipulation is unethical (e.g., environmental epidemiology).
