How does a water footprint differ from an ecological footprint?
Answer and explanation
Correct answer: A water footprint measures water use while an ecological footprint measures demand for biologically productive area
A water footprint estimates the freshwater used directly and indirectly to support a person, product or population, including different sources and pollution components depending on the method. An ecological footprint estimates the biologically productive land and water area needed to provide resources and absorb wastes. They are related sustainability indicators but measure different pressures. Thus A is accurate and the other statements are too narrow or false.
