Green People

Joel Makower‘s 1992 book, The E-Factor, described

…a small band of American Airline flight attendants that started their own effort to recycle cans, bottles, and other waste from flights. They gradually enlisted all 17,000 or so of their fellow flight attendants, eventually creating a systemwide recycling effort without much help from top management. Over time, the flight attendants were able to amass $200,000 from selling recycled materials, and used the money to purchase a plot of land near the Nashville airport and donate it to The Nature Conservancy to protect an endangered coneflower.
