Global sustainability is an essential challenge in our world and for our future, a cause that I am committed to in my personal and professional life. The Organizational Dynamics program has increased my focus and engagement and has resulted in increased awareness in myself personally and those around me, as well as positive behavior change. I review the Sustainability Development courses that I took, then delve more deeply into the two that have affected me most deeply and show how that has translated into action in my own life, both personally and professionally. I examine organizations in New Hampshire that balance the tourism necessary for their success, with preserving the nature which drew the tourists in the first place; I also assess how the surviving grand hotels have embraced sustainability measures in the modern era. I have studied the Earth’s dwindling water supply and seen how some of the world’s largest cities have dealt with a water crisis. After experiencing a water crisis in my own home, I evaluated the response, applied Richter’s principles for sustainable water management, and have seen behaviors and habits change as a result. In my personal and professional life, I have taken on leadership roles and have seen evidence of change. I am encouraged by these results and am motivated to drive further change in the future.
