Sustainability is a big buzzword these days, but what exactly does it mean? Sustainability means meeting your current needs without having a negative impact on the needs of future generations. It also requires you to make environmentally-conscious choices about the way you live. It's not really plausible for most of us to have a completely sustainable home -- one that uses only nature's infinite resources with no affect on the environment around us. But fortunately, there are some measures you can take to make your home more sustainable.
