Sustainability is the ability to "indefinitely" sustain (to hold, continue, keep up). On the one hand, sustain can e understood as "suffering" (th etymology seems to be similar). On the other hand, sustainability opposes any representation of the end; things do not terminate, life is not a circle where everything has a beginning and an end. In a time of consumerism when most things (i.e. goods and relationships) are imagined as short-term and replaceable, sustainability introduces a significant shift.
