Can what we do in our gardens affect our ecological footprint? You bet it does, and we explore here just how.
Do you know what Australia’s ecological footprint is? It’s certainly bigger than that of India, Egypt, Finland or even the United Kingdom, but not greater than that of Canada or the USA. I’m sure you don’t need a reminder, but just in case, the ecological footprint is a measure of the area of land and water it takes to provide a person or population with the resources it uses. It includes productive land and water, that used for roads, cities and other infrastructure and the ecosytems that are required to deal with waste. So it is a measure of human demand on nature’s capacity – a measure of how the natural environment is affected by human impact.
The worldwide footprint is 1.7 of the earth, based on the most recent calculations by the Global Footprint Network, in 2010. That means that the world is consuming 1.7 times the earth’s capacity. Australia’s was 6.8 with the biggest component coming from grazing. So if the whole world was having the treating the environment in the same way as Australia, we’d need 6.8 earths to support us!
