What term describes the overall consequences of human activity on the natural environment?

• A. Environmental impact
• B. Biodiversity index
• C. Sustainable yield
• D. Ecological footprint

Answer: (A)

The overall consequences of human activity on the natural environment are described by environmental impact. This broad term covers all the effects on air, water, land, ecosystems, and climate caused by people—habitat loss, pollution, changes in biodiversity, and resource depletion, among others. It’s not just a single measure, but the full range of outcomes from actions like deforestation, urbanisation, and pollution. Biodiversity index is a specific metric of species variety, not the total set of environmental changes. Sustainable yield refers to how much of a resource can be harvested without depleting it, which is about management of a resource, not the wider environmental effects. Ecological footprint measures the amount of natural resources and ecological services required to support a population’s consumption, which is related to impact but focuses on demand rather than the complete suite of environmental changes.
