Local filmmaker Lesley Topping presents her film A River Returns: A History of the Bronx River at OSH at 4 pm (following the 8th Annual Permaculture Festival).

The film educates viewers on the ways in which the Bronx River is a model for the restoration of urban rivers across the US, and how it has been cared for through an alliance of private and government groups, volunteers, students, and educators.

The screening will be followed by a Q&A with filmmakers, historians, and environmentalists.
