What is ecological footprint?</h3>
- The Global Footprint Network advocates using the ecological footprint to determine how much nature is required to support a certain population or economy.
- The ecological footprint accounting system tracks how much nature is being used and produced.The Ecological Footprint calculates the total productive areas for which a population, a person, or a product competes on the demand side.
- It evaluates the ecological resources required by a specific population or product in order to produce the natural resources it consumes, as well as to absorb its waste, particularly carbon emissions.
- The biocapacity of a city, state, or country, on the supply side, measures how productive its ecological resources are (including cropland, grazing land, forest land, fishing grounds, and built-up land).
- These regions can also be used to absorb the garbage we produce, particularly our carbon emissions from burning fossil fuels, especially if they are left unharvested.
