What term refers to the amount of land, water, and resources people use to live, and how much the Earth can provide to meet that demand?

• A. Ecological Footprint
• B. Carbon Footprint
• C. Food Footprint
• D. Housing Footprint

Answer: (A)

Ecological footprint measures the amount of land, water, and other natural resources a person or population uses to sustain their lifestyle, and it compares that demand to how much the Earth can supply in a given period. It brings together what we consume with the planet’s capacity to regenerate those resources and to absorb our wastes (biocapacity). When our footprint exceeds Earth’s biocapacity, we overshoot, meaning our use is not sustainable. This broader measure differs from a carbon footprint, which focuses only on greenhouse gas emissions.
