Which term best describes the consequences of human activity on ecosystems?

• A. Environmental impact
• B. Environmental benefit
• C. Environmental opportunity
• D. Environmental risk

Answer: (A)

Understanding how human activity changes ecosystems is captured by the term environmental impact. It refers to the effects that actions—like pollution, land use change, resource extraction, or conservation efforts—have on the natural world. These consequences are the actual results seen in ecosystems, and they can be negative, positive, or mixed. The other terms describe narrower ideas: a benefit is only positive outcomes, an opportunity is about chances for some outcome rather than actual effects, and risk centers on the possibility of harm rather than the realized results. Because it covers the range of observed outcomes from human actions on ecosystems, environmental impact is the best fit.
