To sustain is being able to be maintained at a certain rate or level or the ability to be upheld or defended. Sustaining an environment would naturally mean to maintain the level of productiveness and keeping up to the needs or conserving an ecological balance by avoiding depletion of natural resources.

In Mac Pherson Road, sustainability is pretty low due to the fact of low development is being done at that area and in fact lacking to sustain the community needs.

However, due to the fact that low development was done, buildings, lamps, community centre was not installed with more energy saving facilities.

Sustainability is low in the environment whether in energy saving or the sustaining of a good community.
