Post-it notes maker 3M Co. says it will refuse to buy any materials from suppliers that come from threatened forests as part of an agreement with a longtime environmental critic. The policy changes announced Thursday would require suppliers of Twin Cities-based 3M to report original sources of materials.
A very visible protest hung over the Mississippi River Monday in Minneapolis. The conservation group ForestEthics hung a giant 40-foot post-it note from the Washington Avenue Bridge. The group is protesting what it calls 3M’s link to the destruction of endangered forests worldwide.
