What is Sustainability?

It is derived from the Latin word sustinere (tenere, to hold; sus, up). As wikipedia suggests, sustainability is the capacity to endure. Whether it is pertaining to human beings, animals, environment, etc. Everything has sustainability, all things has the capacity to endure. But what does it really mean. As for my course, sustainability is described as how the environment can sustain its productive state. Sustainability involves time. How long can it endure, resist, withstand, etc. We try to make our environment healthy for us to survive. We live in a diverse biological system. There are three things to keep sustainability balanced. These three are called "The Three Pillars of Sustainability" namely, environment, society and economy. These three harmonizes and builds the foundation of a sustainable system. A Venn diagram is used to illustrate the harmony of the three pillars.
