The staff, directors and membership of the Association for the Advancement of Sustainability in Higher Education (AASHE) mourn the passing of Nobel Peace Prize winner Wangari Maathai who died yesterday in her home country of Kenya. Dr. Maathai, who was scheduled to give the opening keynote at AASHE 2011: Creating Sustainable Campuses and Communities, had been hospitalized for ovarian cancer in the preceding weeks. We are deeply saddened by the loss of this world leader of sustainable development who worked for decades on eradicating poverty, improving the environment, championing women’s rights, exposing climate injustice and fighting government corruption. She has brilliantly woven together the many strands of sustainability so that we can see and understand the ways that these elements are all necessary for a better future.
