Lawns catch atmospheric pollutants such as dirt, dust, allergies, and more significant pollutants in addition to carbon dioxide. Turf grasses alone remove an estimated 12 million tons of contaminants from the air in the United States each year, breaking down pollutants and returning dirt and dust to the soil. This process is called "aerobic degradation."
Trees help clean the air by removing large amounts of pollution from the sky. The chemicals absorbed into their leaves and bark are then released back into the atmosphere when they die or are burned. Air quality benefits due to tree cover can be seen across the city, but especially in urban areas where pollution levels are highest.
Grass doesn't just capture gases; it also absorbs noise and vibrations from cars, trucks, and airplanes. This effect is called "silent street" and it helps prevent disturbing noises that come with driving on busy streets. Silent streets are considered a benefit because they reduce stress and traffic accidents due to sound distractions.
Some people think that planting grass in front of your house is a sign of wealth. Actually, it's a waste of money since most grass is not grown for lawns but instead used for livestock feed or played in sports fields. The color and shape of the grass can give you an idea about how much sunlight it gets and if it's maintained regularly. Dark green grass is more efficient at taking up carbon dioxide than light green grass.
The Environmental Advantages of Having a Lawn Unlike hard surfaces like concrete, asphalt, and wood, grass helps to clean the air, trap carbon dioxide, prevent erosion from rainwater runoff, enhance soil, reduce noise pollution, and lower temperatures. These advantages are especially significant for hot, dry regions like the Southwest and Central California where water is scarce and expensive.
The Disadvantages of Grass include the need for regular maintenance and cost. Maintaining a lawn requires mowing, watering, and fertilizing which can be time-consuming and expensive. The amount you spend on your yard will depend on how much you want to invest in it and whether you plan to use natural methods or hire professionals for help. A new lawn can cost as little as $150 but prices can range up to $5000 or more if you choose quality materials and expert advice from beginning to end.
Lawns take up a large part of many people's budgets and can also be energy-intensive processes. Mowing your lawn uses fuel and creates greenhouse gases. Natural methods include using products such as earthworms, compost, mulch, and green spaces in your city that have been maintained by their owners. Professional methods include using companies that provide these services full-time such as landscaping businesses.
1. Natural lawns filter and improve the quality of the air. 1,2 After grass blades catch airborne pollutants, dew and precipitation assist drive them towards the root zone, where dust and dirt return to the soil and soil bacteria help break down pollutants. In fact, studies have shown that natural lawns can reduce asthma attacks by cleaning the air of irritants such as pollen and dander. The American Lung Association recommends keeping your yard mowed regularly for lung health.
2. Grass is able to capture particles from the air - including toxic substances such as arsenic, lead, and mercury - through a process called "adsorption". As these particles come into contact with the grass's surface they lose some of their mass and become attached instead to individual cells within the plant. Once captured, these contaminants cannot re-enter the atmosphere. Instead, they are stored in the soil where they will not harm humans or other organisms.
3. Yes, if you want your yard to be environmentally friendly then a green lawn is the way to go. That being said, there are ways that you can maintain a healthy green lawn while still doing your part to protect our environment. For example, you can mow less often or turn off your mower when not in use to prevent burning the fossil fuels that it takes to power modern appliances.
