Given these statistics, replacing a conventional lawn might seem like a no-brainer for homeowners who want to reduce their carbon footprint and limit their exposure to potentially dangerous chemicals. Here at Rise, we have written extensively about alternative landscaping options to the emblematic green turn lawn that has become the traditional standard. Check out our articles on how to grow a lawn without chemicals, the role of permaculture zones in changing your landscape design, and xeriscaping opportunities to reduce water consumption drastically.
Despite the practicality of these alternative landscaping options, many homeowners across North America will scoff at the idea of getting rid of their green lawn. Might there be a way for homeowners to enjoy a green lawn without the environmental costs associated with pesticide use, water use for irrigation, and fossil fuel use for maintenance?
It is important to note that natural grasslands and prairies can act as a carbon "sink." They essentially capture excess amounts of carbon dioxide from the air and deposit that carbon in the fertile soil. Indeed, most lawns do not boast the carbon capturing potential of natural prairies. But, turning your yard into a "prairie garden" could be another strategy that allows homeowners to do their part to sequester carbon.
Is Artificial Grass Healthy?
A drawback associated with artificial grass is that there are several health concerns related to these products. Many turf products come pre-treated with biocides. This step is taken because some studies have found that synthetic turf has been associated with an increased risk of infections from methicillin-resistant Staphylococcus aureus. Recent laboratory tests carried about by the Public Employees for Environmental Responsibility (PEER) find that many turf products contain the highly toxic fluorinated chemicals known as PFAS. The US Centers for Disease Control and Prevention (CDC) states that exposure to PFAS has a host of health effects associated, including cancer, liver damage, decreased fertility, and increased risk of asthma and thyroid disease. That's not exactly what you want in the areas where your children play.
Besides having a vast embodied energy footprint, artificial grass also essentially eliminates the biophilic benefits of spending time outdoors. Moreover, there are several serious health concerns related to artificial turf products that homeowners should consider. If you decide that artificial grass is the best option for your home, we recommend looking for products made from bio-based fibers. And also, it might not hurt to leave some space for some natural plants as well!
