Turfgrass, like that found in our lawns, is much cooler than asphalt or cement, acting as an “air conditioner” for the surrounding area (lawns can be 22 degrees cooler than urban asphalt “heat islands”).
Healthy turfgrass has many miles of fibrous roots that hold soil and filter rainwater. (National Arboretum Grass Roots Project) A single grass plant can have more than 300 miles of roots.
It is estimated that a 50 by 50 foot lawn (2,500 square feet), releases enough oxygen for a family of four, while absorbing carbon dioxide, hydrogen fluoride, and perosyacetyle nitrate.
