Which of the following best defines environmental science?

• A movement dedicated to protecting the environment

• The study of living organisms and the processes that allow them to survive

• The study of interactions between the natural world and humans

• The study of Earth’s physical structure and processes

Environmental science is considered interdisciplinary because:

• It focuses on only one area of study

• It includes multiple fields, such as politics, ethics, and economics in addition to science

• It is not technically a scientific field, but a political and social movement

• It excludes human involvement and only focuses on the natural world

• Many scientists are involved in the field and must collaborate
