She offered her testimony for many public hearings. Arlene also remains concerned about land use and water pollution issues. Arlene was initially attracted to MCE because it was the only local environmental activist organization around in the 1970’s. She still sees MCE as the best place for her volunteer energy. Her career as a librarian gave her the opportunity and the resources to do research on environmental problems, and the governmental regulations that are supposed to protect us.
