In short, sustainable living means practising a lifestyle that uses as few of Earths natural resources as possible, in an attempt to create the least amount of environmental damage for future generations.
Those who are committed to living a sustainable lifestyle will often try to reduce their carbon footprint by changing their means of transport, energy consumption and their diet- living in a way that is consistent with sustainability, and in balance with, and respectful of humanitys symbiotic relationship with the Earths natural ecology and cycles.Basically, sustainable living involves living on the Earth as lightly as possible- meeting ones needs in the present without compromising the needs of future generations, so they too can enjoy the same high quality of life that people do today.
