ABSTRACT

The idea of the ecological footprint dates from the 1990s when two Canadian academics put forward the metaphor as a means of bringing home to people the impact that they were having on the ability of the Earth’s biosphere to support life. It’s a clever idea because we all walk on the Earth every day, and the size of our tread – our impact – varies enormously across the globe: from country to country, and from person to person within a country.
