My definition of, Sustainability: It is working towards achieving the three pillars of sustainability: environmental, social, and economic sustainability.

Environmental sustainability is aiming to decrease your footprint on the plant. It means using less resources and having a lighter impact on the plant

Social Sustainability is working towards equity- that all people have the same access to resources

Economic sustainability is about understand the value of items and incorporating externalities into the actual cost. It is about paying people fairly.
