1. The branch of philosophy that studies the moral relationship between
humans and the natural environment is called:
A) Environmental ethics
B) Environmental economics
C) Conservation biology
D) Political ecology
Correct Answer: Environmental ethics
Rationale: Environmental ethics explores questions of right and wrong regarding
how we treat nature, other species, and future generations. It provides the
philosophical foundation for many environmental policies and personal
behaviors.
2. An anthropocentric worldview holds that:
A) All living organisms have equal moral standing
B) Human beings are the central or most significant entities in the moral
universe
C) Ecosystems have intrinsic value independent of human needs
D) Only sentient animals deserve moral consideration
Correct Answer: Human beings are the central or most significant entities in the
moral universe
,Rationale: Anthropocentrism evaluates the environment in terms of its
usefulness to humans. It contrasts with biocentrism (all life has value) and
ecocentrism (whole ecosystems have value).
3. A worldview that grants equal moral worth to all living things, regardless of
their utility to humans, is:
A) Anthropocentrism
B) Ecocentrism
C) Biocentrism
D) Stewardship
Correct Answer: Biocentrism
Rationale: Biocentrism extends inherent value to every individual organism.
Ecocentrism goes further, valuing entire ecological systems, including non‑living
components.
4. Aldo Leopold's "land ethic" is a classic expression of which ethical
perspective?
A) Anthropocentrism
B) Biocentrism
C) Instrumental value
D) Ecocentrism
Correct Answer: Ecocentrism
, Rationale: Leopold argued that humans are members of a biotic community and
should treat soils, waters, plants, and animals with moral respect. This holistic,
system‑centered view defines ecocentrism.
5. The term for the benefits that humans obtain freely from the natural
environment, such as pollination and water purification, is:
A) Ecosystem services
B) Natural capital
C) Ecological footprint
D) Green accounting
Correct Answer: Ecosystem services
Rationale: Ecosystem services are grouped into provisioning, regulating,
supporting, and cultural services. Natural capital is the stock of resources that
yields these services.
6. The provisioning ecosystem service that provides raw materials like timber,
fiber, and fuel is classified as a(n):
A) Regulating service
B) Provisioning service
C) Cultural service
D) Supporting service
Correct Answer: Provisioning service
