    Preserving China’s Biodiversity

    As the executive director of the Shan Shui Conservation Center in China, Irene Xiangying Shi ’13 MESC is helping conservation efforts in the Tibetan Plateau and southern regions. The Center focuses its work on urban ecosystems and endangered species, such as giant pandas and snow leopards. 

    “If we have the right incentives,” she says, “people will conserve nature in the best way." Her efforts have helped build a biodiversity conservation alliance, an information sharing platform on biodiversity, and long-term funding mechanisms to continue work on these issues.

    Waste Warrior

    As founding chair of the New York City Public Housing Authority Recycling Committee, DeNeile Cooper ’22 MEM is working to boost recycling efforts in public housing units.

    Only 2% of waste from NYCHA units is recycled. Nationally, that rate is 32%.

    “This work has been successful so far because it involves a variety of stakeholders who bring unique perspectives to create programs that work for everyone,” says Cooper, who is a member of the Manhattan Solid Waste Advisory Board.

    As a public school teacher in New York City watching socially marginalized Black and Latinx students struggle with inequalities in education and health issues from an emerging lead poisoning crisis, A.J. Hudson ’19 MESc was moved to take action. He helped found a public high school and led neighborhood workshops on climate justice and political action efforts.

    He also helped organize coalitions to pass New York’s Climate Leadership and Community Protection Act and helped plan the 2019  Youth Climate Summit, the nation’s largest gathering of young people of color passionate about climate change.
