Grass makes our environment greener in many ways. One of the most important is the job it does as an air filter, trapping dirt and removing smoke and other air pollutants to improve air quality and minimize the negative health impact from smog and dust.
If you've ever walked through a construction site or a similar dry, unplanted area on a windy day, you have some idea of what life might be like without grass. Clouds of windblown dust make for difficult breathing, irritated eyes, and reduced visibility. But grass roots help trap dirt and dust. In fact, every year grass traps millions of tons of dirt and dust that would otherwise be blowing around unhindered.
Air pollutants such as carbon dioxide and sulfur dioxide continue to be a major concern worldwide. Maintaining a healthy lawn will help remove some of these contaminants from the atmosphere. In a years time, one acre of flourishing grass can absorb hundreds of pounds of sulfur dioxide and 6 tons of carbon dioxide from the air.
