Join us for a screening of To Build a Better Ditch, a short film produced by Ravenswood Media that describes the environmental benefits of two-stage ditch design. This design demonstrates how a change in the way agricultural ditches are made can not only reduce erosion and improve water quality but can also lower maintenance costs for the farmer. After the film, we’ll be joined by guest speakers for a conversation about conservation and water quality. Guest speakers include John Legge, director for Great Lakes Conservation, The Nature Conservancy. To register, email adultprograms@naturemuseum. org or call 773-755-5100, ext. 5028.
