Pass a law requiring direct mail advertisers and charities to purge their mailing lists at least every five years and remove any names they have not heard from in that time.
Why is this important?
Ninety percent of my mail goes straight into the garbage can. We all get multiple ads for products we don't want and endless solicitations from charities. Also, a friend whose wife died 18 years ago still gets hundreds of solicitations for her, despite written requests to remove her name. We need a law to stop this. It would save many trees and decrease the landfills on our planet. We could also be more sure the money we donate to charities is not thrown away.
