Evolving Definitions of Sustainablity
The broad definition of sustainability is meeting the needs of the present without compromising the ability of future generations to meet their own needs. There are a lot of factors that contribute to the various aspects of sustainability, such as; the population and available living space, pollution of land, water and air, climate change, use of manufacturing materials, energy demands, etc. There is so much involved in the sustainability equation that universities are teaching sustainability as a science major. Included are sustainabilty accounting, or how to quantify sustainability and sustainability governance, or how to control sustainability. The latest idea that I ran across is that sustainability should include preservation of our cultural knowledge. So not only is sustainability applicable to our everday lifestyles, but also to our historical social perpetuation. As the issues of sustainability become more and more complex, all I can do is to try to keep up with the latest information.

Good work so far.
What are the needs of the present? As you comment about social perpetuation illustrates, the needs go beyond food, clothing, and shelter.
Sustainability is not a set of means, it is a description of the end state, the goal you are seeking.
What are we seeking?

I think the key word is NEEDS. We should be seeking to make sure our needs are met – not our wants.
