Turfgrass can boost your oxygen footprint.
Compared to bare ground, non-green areas, and lawn substitutes, such as painted concrete or even artificial turf, actual grass and green areas generate oxygen. For example, a turf area 50′ x 50′ produces enough oxygen to meet the everyday needs of a family of four and each acre of grass produces enough oxygen for 64 people a day.

Lawns do an excellent job of capturing water runoff and lessening dust and particulate matter pollution, versus alternatives such as hard surfaces, mulched areas and impervious or bare surfaces.
According to a Council for Agricultural Science and Technology (CAST) 2006 Publication, turfgrass not only decreases dust emissions, but for controlling soil erosion, a live, functioning grass cover, including urban lawns, is a cost-effective option, since a grass root system is one of the most effective in soil stabilization because of the fibrous, dense character of its roots.
