Grass is a huge part of a healthy environment by generating oxygen, filtering carbon and dust out the air, and protecting soils and groundwaters from erosion and evaporation. All told, turfgrass has a major impact in making our environment habitable.

A 50’x 50′ lawn produces enough oxygen for a family of four!
Grass protects against erosion
Planting turfgrass helps the very ground its deposited in. Extensive root systems on turf grasses lock soil in place and protect it from loss by wind and water. Erosion of soil by water is effectively controlled by grasses as they intercept raindrops before they disturb the soil, and they also slow the flow of water which minimizes soil loss.
Grass protects our water
Groundwater is enhanced in two ways by a dense covering of turf. Turfgrasses increase infiltration of water and clean the water as it passes which in turn recharges the underground water supplies used by all of us.
Grass protects the air
The air we breathe is also made better when we opt for grass. Turfgrasses in the United States annually cleanse the air of an estimated 12 million tons of dust and dirt.
Grass sequesters carbon
Rather than being released into the atmosphere and adding to greenhouse gasses, carbon, sequestered by grass, is held in soil where it eventually becomes organic matter. A healthy, average size U.S. lawn (about 10,000 square feet) can collect and store up to 300 pounds of carbon per year.
​
Pollutants, such as carbon dioxide and sulfur dioxide, are absorbed by turfgrasses thereby rendering the air fit to breathe. American lawns capture about 5% of the carbon dioxide from the atmosphere each year.
