What Is Sustainability?

Sustainability is a word that gets bandied about a lot, and i wanted to start with the two of you telling me, what is your definition of that word? I'll jump right in. We want to talk to day about stainability. What i thinkabout is, how do we make it better now? How do we start ssing towards a better planet and making the world better? When i think of 'sustained ability'  the first people who come to mind would be air lines, auto makers, people who have obvious large carbon footprints. Tell me why tech companies also need to be as mindful of that.
