What is sustainability?

I feel the more you learn about the various meaning that have been attributed to the word sustainability the more I realize that the inadequacy of any word to contain so much content. I came in with my own idea of what the word meant, but I discovered so many layers, both of ideas attached to the word and of complexity of to what I already thought I knew. I feel the basis of sustainability is understanding that everything is connected. Everything that we do affects someone or something else, both here in the present and in the future. Understanding the breadth of our actions means that we must be mindful of the things we do, trying our best to leave others at peace whenever possible. And the term others I feel also must take on a broader meaning when used in regards to sustainability. Others means the boy next door, the tree in your backyard, the lake you visited as a kid, and the people who make your clothes. While fully understanding the intricacies of our connection to the world is impossible, sustainability is a promise to seek these connections out and insure that what we do does not harm others.
