Artificial grass is marketed as a durable, long-lasting alternative to real grass. However, fake grass can suffer from surface degradation over time, including fading and fiber loss. Despite its initial resilience, the synthetic materials may deteriorate, affecting its performance and aesthetic appeal. Maintaining its appearance and functionality often requires regular cleaning and infill replacement, which contradicts its low-maintenance claims and adds to the long-term upkeep.

The main reason natural grass is being replaced for the perceived durability of synthetic turf is often the lack of initial maintenance investment. With proper upkeep, a natural grass field can also provide a durable and long-lasting playable surface. It can withstand diverse weather conditions and recover from damage. Its natural growth cycle allows it to renew itself, offering a fresh and green surface even after periods of wear and tear.

Artificial grass certainly offers certain advantages, such as consistent playing conditions due to the absence of growth-related variability. These factors allow for extended playing hours and more predictable surface conditions. However, these benefits come at the cost of playability.

Fake grass has a less forgiving surface, with increased friction and reduced shock absorption. These factors are associated with an increased risk of injuries, particularly in the lower extremities. A 2019 study by the American Journal of Sports Medicine reviewed data from the NFL and found that the rate of non-contact lower extreme injuries is 28% higher on artificial turf. This includes a higher rate of non-contact knee, foot, and ankle injuries.

Meanwhile, natural grass provides a playing experience that artificial grass cannot replicate. The natural feel of grass, with its variability in texture and surface, adds to the game’s authenticity. It shows that despite the benefits artificial grass offers in terms of maintenance and versatility, the increased injury risk makes it a controversial choice, particularly for high-impact sports.

Artificial grass is not only harder and less forgiving than natural grass, but it can also get excessively hot, with surface temperatures reaching up to 160°F. This extreme heat poses significant risks, including heat-related injuries and burns, which are particularly concerning in contact sports. Heat-related injuries, like heat exhaustion and heatstroke, are more likely to occur on artificial turf with its inability to dissipate heat effectively, unlike natural grass.

In contrast, natural grass maintains a cooler surface temperature, significantly improving player comfort and performance, particularly in warmer weather. Additionally, natural grass does not pose the same health risks as artificial turf, which can contain carcinogens and other hazardous chemicals that may leach into the soil, potentially polluting the waterways and harming human health and ecosystems.

The tendency of artificial grass to retain and radiate heat can exacerbate local temperatures, contributing to the urban heat island effect. Additionally, artificial turf is made from PFAS (per- and polyfluoroalkyl substances) and other synthetic materials. These materials pose long-term environmental concerns, especially when the turf reaches the end of its lifespan and ends up in landfills, contributing to pollution and environmental degradation.

Natural grass, in contrast, plays a crucial role in environmental sustainability. It provides a natural cooling effect, reducing urban temperatures by up to 30° compared to surfaces like concrete and asphalt. This cooling is equivalent to having a large air conditioning system; for example, a single high school baseball field can provide up to 70 tons of cooling, benefiting the environment and reducing energy consumption in nearby buildings. Additionally, natural grass contributes to carbon sequestration by absorbing carbon dioxide and releasing oxygen, thus improving air quality. It also protects water supplies through natural filtration processes, making it a much more eco-friendly option than artificial turf.

Artificial grass is widely marketed as a no-water alternative to natural grass, which may seem like an environmental advantage. However, while it does not require watering to stay green, it does need regular cleaning to remove dust, debris, and other contaminants. This process can involve significant water use, offsetting the perceived water savings. Additionally, unlike natural grass, synthetic grass does not absorb rainwater or contribute to the water cycle. It can exacerbate runoff and reduce groundwater recharge, limiting environmental benefits.

On the other hand, natural grass certainly requires water. However, the broader availability of more drought-tolerant grass varieties has made it more sustainable in areas prone to hot and dry environments. For example, bermudagrass is specifically cultivated to withstand challenging conditions. It has a deep root system that helps access water from deeper soil layers, allowing it to survive longer periods without water.

Proper watering practices and efficient irrigation methods, such as drip irrigation and smart controllers, further contribute to water conservation by delivering precise amounts of water directly to the root zone. With proper care and maintenance, real grass can stay healthy amid drought.

Both natural and artificial grass require significant investment, but the long-term costs can differ widely. Initial artificial grass costs include site preparation, coverage, infill materials, drainage systems, and labor. These costs can be substantial, but proponents argue that the lower maintenance costs offset the initial expense. However, artificial turf also requires routine maintenance, such as replacing infill materials and maintaining drainage systems to maintain playability, which can add up over time. Additionally, fake grass will eventually have to be replaced, adding to long-term costs.

A natural lawn also requires investment in coverage—whether through seed, sod, or other vegetative methods—irrigation systems, labor, and ongoing maintenance treatments. However, with proper care, natural grass can be more cost-effective in the long term. The ability to rejuvenate and recover from wear can translate to lower maintenance costs, making natural grass a more sustainable solution.

When considering athletic and playing fields, natural grass remains the clear winner. Its benefits extend beyond aesthetics. Its natural shock absorption reduces the risk of injuries, while its cooler surface temperature improves player performance and comfort, especially during hot weather. Natural grass also supports environmental sustainability by promoting carbon sequestration, reducing urban heat islands, and contributing to water conservation. While artificial turf may seem low-maintenance, the environmental and health implications make natural grass the more responsible and cost-effective option.
