Introduction
Welcome to your comprehensive exam preparation resource for Living in the
Environment, 20th Edition by G. Tyler Miller and Scott Spoolman. This test bank
contains 200 multiple-choice questions carefully designed to mirror the types of
questions you will encounter on quizzes, midterms, and final exams in
environmental science courses
1. Which of the following best defines environmental sustainability?
a) Using resources without regard for future generations
b) Meeting present needs without compromising the ability of future generations to meet
their own needs
c) Maximizing economic growth at any environmental cost
d) Eliminating all human impact on the environment
Rationale Sustainability balances current human needs with long-term ecological
:
health. The Brundtland Commission definition is the standard.
2. The three scientific principles of sustainability are: reliance on solar energy,
biodiversity, and ________________.
a) Chemical cycling (nutrient cycling)
b) Economic growth
c) Urbanization
d) Fossil fuel combustion
,Rationale Solar energy, biodiversity, and chemical cycling are the foundational
:
principles that sustain life on Earth.
3. Which activity contributes most directly to the ecological footprint of a nation?
a) Planting trees
b) Burning coal for electricity
c) Recycling aluminum cans
d) Using solar panels
Rationale Ecological footprint measures resource consumption and waste absorption.
:
Burning fossil fuels increases carbon footprint significantly.
4. The tragedy of the commons refers to:
a) Overuse of shared resources because individuals act in self-interest
b) Government regulation of private land
c) The extinction of common species
d) Overuse of shared resources due to self-interest
Rationale Garrett Hardin’s concept explains why shared resources (air, water, fisheries)
:
are degraded when no one has ownership.
5. Which country has the largest per capita ecological footprint?
a) India
b) China
c) United States
d) Brazil
Rationale The U.S. footprint is about 8 hectares per person, far above the global
:
average of 2.7 hectares.
6. The IPAT model (Impact = Population × Affluence × Technology) suggests that:
a) Only population matters
b) All three factors multiply to determine environmental impact
c) Technology always reduces impact
,d) Affluence has no effect
Rationale: IPAT shows that environmental impact is a product of population size,
consumption per person, and technological efficiency.
7. Which is an example of point source pollution?
a) Agricultural runoff from many farms
b) A pipe discharging industrial waste into a river
c) Air pollution from thousands of cars
d) Sediment from construction sites
Rationale: Point source comes from a single, identifiable location (e.g., factory pipe).
Nonpoint source is diffuse.
8. Natural capital includes:
a) Money in banks
b) Forests, water, and mineral deposits
c) Human labor
d) Factories and machinery
Rationale: Natural capital is Earth’s stock of natural resources and ecosystem services.
9. The precautionary principle states that:
a) We must prove harm before taking action
b) Lack of scientific certainty should not delay action to prevent serious environmental
harm
c) Only economic costs matter
d) Technology will solve all problems
Rationale This principle shifts burden of proof – when risk is high, act early even
:
without full evidence.
10. Which is a nonrenewable resource?
a) Solar energy
b) Crude oil
c) Timber
d) Fresh water
Rationale Nonrenewable resources exist in fixed amounts and are depleted by use
:
, (fossil fuels, minerals).
11. Ecosystem services provided by forests include:
a) Carbon sequestration and water purification
b) Manufacturing lumber
c) Parking lots
d) Mining coal
Rationale Ecosystem services are natural processes like pollination, climate regulation,
:
and nutrient cycling.
12. The anthropocene epoch is characterized by:
a) Dominance of dinosaurs
b) Human activity as the primary driver of planetary change
c) Ice ages
d) No human influence
Rationale Anthropocene (unofficial) highlights that humans have become a geologic
:
force.
13. Which is a positive feedback loop in climate change?
a) Ice albedo effect: melting ice exposes darker water, absorbing more heat, causing
more melting
b) Plants absorbing CO₂
c) Melting ice reduces albedo, increasing warming
d) Ocean uptake of heat
Rationale: Positive feedback amplifies change. Ice-albedo feedback accelerates
warming.
25. Per capita ecological footprint is calculated by:
a) Total footprint divided by population
b) Population divided by total footprint
c) Total footprint / population
d) GDP / footprint
