Tiny parks boost wildlife and health

Small green spaces help butterflies, birds, and human health in cities.

Americans with easier access to parks have lower rates of obesity, high blood pressure, and diabetes.

“All sorts of organizations lined up, scrambled, put in grant proposals, were awarded funds, and were beginning to do the projects”

North Richmond received $19 million for green spaces but most funds remain unfulfilled.
