sustain? who? where?

I am being prompted by a professor to collect 10
email responses on the following questions:

What does it mean to sustain something?

Sustainability is a popular word today, but what
does it actually mean to approach an issue, a
concept, a thing, or even something as large
as society, as something to be sustained?

Take a few minutes to answer these questions and
respond back to me at,
