Ecological footprint: a scientific method for determining in what areas and how heavily humans impact on the environment. The method employs the magnitude of the uses of, and stresses on, natural capital, such as consumption of oil and food products, to calculate the surface area which would be required to provide these resources in a sustainable manner (hypothetical area requirement in global hectares).
