Sustainability; in its simplest terms, means the “well being for all, within the means of nature”. This is achieved by the use of global resources at a rate that allows natural regeneration, and minimises damage to the environment. In essence, it is the usage of resources in a manner which will ensure the prolonging and longevity of earth and the human race. The main factors that we as a human race need to look at are re-examining policies on protection of the environment, our responsibility as a society and the practice of our economics. Through the conservation and responsible use of non renewable resources such as coal and fossil fuels, that take millions of years to form into what we know and use them as today, there will be enough to provide for the future generations. Our ecological footprint is a measure to recognise how much we take away from nature; it takes into account how much agricultural, grazing, forest land and sea area it takes to provide for us based on the resources we consume. Through a more sustainable way of living, our ecological footprints can be reduced; with the amount of resources that we consume being consumed at a much lesser rate where there is time for it regenerate, the amount of natural area needed to sustain us will decrease as well. Since our ecological footprint is based on the amount of land it takes to provide for our resource intake, by taking in a more steady and conservative amount of resources we are reducing the amount of land we need.
