I enjoyed reviewing your presentation on sustainability in business. The chronological order to which you explain your topic helps me better understand the concept. One question that I do have is of the four pilliars of sustainability is there one pillar to which is more important to sustainability than the others. I personally would think that economic pillar would be most important of them all due to the fact that without economic sustainability in an organzation it would become very difficult for a company to be able to build on the other pillars. I would like to hear after the research conducted on sustainability in business if there is a single more important pillar than the other.
