Dear Readers:

We would like to use the following quotation at our workshops this summer,
Linking People, Purpose, and Place: An Ecological Approach to Agriculture.
We need the source and exact wording. Thank you, Heidi Carter, Education

"In our conversion of natural systems to agriculture, we have never known
what we were doing because we have never known what we were undoing."
Wendell Berry
