Today’s Solutions: December 15, 2025

New York City has just finished planting 1 million new trees within an eight-year time frame. The MillionTreesNYC campaign was launched eight years ago by former Mayor Bloomberg and Bette Midler. The singer and actress runs the nonprofit New York Restoration Project, which helps revitalize green spaces in low-income neighborhoods.
