|Stay Cool: Find a Tree|
Major cities are planting more trees to beat the heat

That's right: Big leaf maple, walnut, oak and catalpa are out there on the city street corners, prepared to offer you a critical service, according to forestry researchers.
Trees can help by dropping city temperatures, preserving pavement, foreshortening the release of gasoline vapors from parked cars, and offering city dwellers a scientifically validated peaceful and easy feeling.
