Don't act your shoesize
Everything we do and consume as humans has an impact on the environment. Regardless of whether you're a vegetarian or not, vegetation has probably been cleared to grow the food you eat. Similarly, whether you drive to work or catch a train, non-renewable resources are being utilised to power both modes of transport.
Originally proposed as a simple method for comparing the sustainability of
resource usage amongst populations, an ecological footprint calculates the land
area that would be needed to sustain an individual (or town, company or country)
indefinitely.
To determine whether a population has a sustainable ecological
footprint, the figure calculated is compared with the land area actually available.
Generally, if you live in an industrialised country like Australia you are
likely to have an ecological footprint four times the size of a person who lives
in a low-income country such as Costa Rica. The latest calculation of global ecological footprints estimates that the average for all people on Earth is 2.18 hectares. The average Australian footprint is 7.09 hectares.
To stay within the Earth's carrying capacity everyone on Earth would need an average footprint of 1.89 hectares - so we are currently over the limit and rapidly depleting the Earth's resources.
