Turfgrass, like that found in our lawns, is much cooler than asphalt or cement. It acts 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. According to NASA, one person consumes 0.84 kg of oxygen each day. This means that one square foot of grass will produce approximately half a kilogram of oxygen a day. (The Lawn Institute)
Research has found that people find stress relief and healing when interacting with nature or even when just viewing nature on a computer screen or through a window. (Nature Sacred.org)
