ecological footprint
by mathis wackernagel and bert beyers
everyone, big or small, has an ecological footprint. how much nature people need depends on what they eat, how they dress, what their home is like, how they move around, and how they get rid of their waste. all of that can be measured. the resulting data allows us to determine the area of biologically productive land and water that is required to grow food, produce fiber for clothing, build houses to shelter people, and absorb their waste. we can measure the carbon dioxide from burning coal, gas, and oil. in the end, we all live on what the \global farm\ provides, and we can accurately measure what the farm provides, and what people consume.
