"Sustainability is recognizing that, as humans, we are stewards of this planet and that our actions lead to incredible consequences, positive and negative. By understanding that, we can create the progress that the world needs – both socially, environmentally and economically – that makes sure the legacy of humanity exits in a responsible way."

Debbie Namugayi, a 2014 School of Sustainability Master of Arts graduate, urges humans to be stewards of the environment.
