Sounds to me like you are taking a biased course in UN Agenda 21 politics. Http://en.wikipedia.org/wiki/Agenda_21
Clearly the answer you teacher is looking for is “your Carbon Footprint”. Http://en.wikipedia.org/wiki/Carbon_footprint
While this has much to do with UN politics as determined by the Copenhagen Climate Council, http://en.wikipedia.org/wiki/Copenhagen_Climate_Council#Unlocking_the_Climate_Code:_Innovation_in_Climate_and_Energy
it has nothing to do with the definition of “sustainability”:

“Sustainability is the capacity to endure. In ecology the word describes how biological systems remain diverse and productive over time. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. For humans, sustainability is the potential for long-term maintenance of well being, which has environmental, economic, and social dimensions.” — http://en.wikipedia.org/wiki/Sustainability

Production of CO2 is actually part of the natural cycle of life. Http://en.wikipedia.org/wiki/Terrestrial_biological_carbon_cycle
CO2 production is also part of a much greater inorganic cycle that dwarfs the biological one. Http://en.wikipedia.org/wiki/File:CO2_pump_hg.svg
The political notion that a carbon footprint has something to do with sustainability [1] is due to the pseudo scientific [2] notion that additional CO2 would be a major climate driver. Http://members.shaw.ca/sch25/FOS/Climate_Change_Science.html#Greenhouse
This is why the UN promotes afforestation to combat global warming [3] even though it is evident that trees cause global warming. [4] Given the track record of these pseudo scientists, [5] the misguided effort to make CO2 abatement the corner stone of government policy [6] should come as no surprise. [7]

In design, sustainability means an object’s ability to last a log time using very little energy. If your chair had a motor assisted lever mechanism, it would be more sustainable if the motor was somehow recharged by the person sitting in the chair or operating a pump. If your lamp needed a Burt’s of energy every time you turned it on, it would not be very sustainable.

It’s been thought of before- look in older National Geographic magazines.

The ocean is a rough place for any equipment and a very expensive place to work in.
