Synthetic turf is everywhere—from your kid’s playground to local sports fields to professional stadiums. Praised for its durability and low maintenance, it’s clear why this grass alternative has gained popularity. However, beneath the lush green surface, synthetic turf fields raise concerns about health risks, environmental impact, and a lack of regulatory oversight.

The health impacts of synthetic turf are among the most pressing issues in the debate over its regulation. Research has shown that certain materials commonly used in synthetic turf, particularly crumb rubber infill, can contain potentially harmful chemicals, including heavy metals, the “forever chemicals” known as PFAs, and volatile organic compounds (VOCs).^{1, 2} Studies linking these chemicals to cancer and respiratory issues have raised alarms, especially when considering that young athletes spend years playing on these fields.^{3, 4}

In addition to health risks, synthetic turf fields pose substantial environmental concerns. Unlike natural grass, which can help mitigate urban heat, synthetic turf can exacerbate the urban heat island effect, with field temperatures sometimes exceeding 160°F on hot days.⁵ Furthermore, the synthetic fibers used in the turf grass blades contribute to microplastic pollution, contaminating water sources and threatening local ecosystems.^{6, 7} Lastly, when fields reach the end of their lifespan—usually within 8 to 10 years—the disposal of synthetic turf poses significant waste management challenges.⁸ The tires recycled to create these fields ultimately end up where they came from: landfills.⁹

Beyond the environmental damage, there are additional concerns for athletes’ safety. While great for softening athletes’ impacts, the turf’s surface has been linked to various potential health issues, from skin and respiratory irritations to increased rates of ACL injuries and concussions.^{10, 11, 12, 13, 14} Additionally, synthetic turf can become extremely dangerous on hot days, reaching temperatures up to 60 degrees hotter than natural grass.^{15, 16} This presents a considerable risk of heat stroke for athletes and children.¹⁷

Despite these risks, regulatory oversight is sorely lacking in the U.S., leading to a patchwork of state and local rules with inconsistent standards.¹⁸ Although the Environmental Protection Agency (EPA) and the Synthetic Turf Council have provided oversight regarding synthetic turf’s contents,^{19, 20} they have not provided comprehensive guidance detailing the long-term effects on athletes’ safety and health.²¹ Additionally, misinformation is being rapidly spread by turf field producers using limited inconclusive tests to gain localities’ trust.²² Companies claiming to be PFA-free have been found to be inaccurate.²³ Without regulatory oversight, communities face challenges in addressing misinformation and managing synthetic turf independently.

Some states, like California and New York, have taken proactive measures, funding studies, and limiting the use of certain materials in synthetic fields.^{24, 25, 26, 27} As Kelly Shannon McNeil, associate director of the nonprofit Los Angeles Waterkeeper, put it, “[w]e’re looking at all of the different ways we can limit exposure to PFAS in our communities, and banning synthetic turf would be an immediate opportunity to do so.”²⁸ New York has also taken steps to ban PFAs found in synthetic turf grass blades. A recent bill has been approved to amend the environmental conservation law to include a ban on PFAs in carpets, including “synthetic turf.”²⁹ New bills are being introduced to eliminate the use of crumb rubber in synthetic turf fields; however, they are still in the early phases.³⁰

Meanwhile, other states have adopted little oversight, meaning millions of players—kids and adults—are exposed to potential risks.^{31, 32} PEER Science Policy Director Kyla Bennett, a scientist and lawyer formerly with the U.S. Environmental Protection Agency (EPA), states that “[o]ur current embryonic state of regulation makes it difficult to trace the life cycle impacts of these highly toxic chemicals from production to disposal.”³³ In other words, conducting long-term research on this subject may be difficult without federal regulation mandating that turf fields be produced similarly.

While the U.S. lags in regulatory action, other countries have taken a different approach. The European Union, for instance, will phase out crumb rubber infill prospectively, given its potential health and environmental risks, and is moving toward banning microplastics in synthetic fields altogether by 2030.^{34, 35, 36} Canada has also been exploring changes to address safety and environmental concerns related to synthetic turf, and several provinces have initiated studies into alternatives that could lower health risks.³⁷

Moreover, many advocates are calling for a unified regulatory approach in the U.S. and suggest that the federal government set baseline standards to ensure nationwide safety. Proposed measures include mandating safer materials, implementing heat-mitigation guidelines, and establishing rules to hold field operators liable for injuries related to synthetic turf risks.^{38, 39}

However, there may be another option: organic grass. Advocates are pushing to include organically maintained natural grass in discussions over synthetic turf use.⁴⁰ Since synthetic turf must be replaced every 8 to 10 years, and no current recycling program exists, these fields can cause more harm than good when they end up in landfills.^{41, 42} States that replace the fields with organic grass instead might resolve these underlying issues.

For now, synthetic turf fields remain popular for their low maintenance and resilience, but as awareness grows, so does the call for greater accountability. Until stricter regulations or change take hold, experts advise that parents, players, and coaches exercise caution—especially on hot days—and keep pushing for transparency about the materials in their local fields.

Reliable energy is a commodity that every American has grown accustomed to. Whether plugging in our toasters in the morning to make the perfect bagel sandwich, maintaining comfortable temperatures in our living spaces during the winter, or being held on a ventilator at the hospital, having a reliable energy grid is essential to our society. Additionally, as we combat the current climate crisis, America has expanded its green energy infrastructure to where renewable energy generates over 20% of our electricity. [1] While this may sound like a promising step toward a sustainable future, our aging energy grid and infrastructure are running into a higher risk of failure with every green advancement, particularly with solar energy. This dilemma has been described as the Duck Curve Problem.

The top line of this graph represents the grid’s energy demand from nonrenewable sources over 24 hours, while the bottom line shows the demand when solar renewable energy is factored in. The significant drop in midday energy demand provided by solar energy, contrasted with the sharp rise in the evening, creates the famous ‘duck’ shape seen in the graph. This steep and quick rise in energy demand puts huge strains on nonrenewable power plants which risk overgeneration to compensate for the energy use differential. This imposes higher prices on consumers, causes infrastructure damage, and threatens our national security.

To curtail this problem, the Biden Administration, under the Infrastructure Investment and Jobs Act (IIJA), has launched a joint grid modernization initiative with twenty-one states toupgrade approximately 100,000 miles of existing transmission lines. [2] This will allow for advancements in battery technology, which will help store midday solar energy and allow for a gradual release of energy when the sun goes down, which will reduce the strain on power plants. Recently, the California Energy Commission has used IIJA funding to expand 100 miles to their power grid to allow multiple sources of renewable energy input such as wind and hydroelectric, to reduce the effects of the duck curve. [3] This is an effective solution because hydroelectric and wind energy input will buffer the drastic evening energy demand.

While the IIJA is a critical step toward enhancing the reliability of the U.S. power grid, further state-level legislative action is needed to meet renewable energy goals without posing a threat to our energy grid infastructure. California’s Energy Storage Mandate serves as a key example. This innovative mandate requires the state’s three major utility companies: Pacific Gas and Electric, Southern California Edison, and San Diego Gas & Electric to procure a combined 1,325 megawatts (MW) of energy storage over ten years. [4] This initiative has proven highly successful, as all three utilities have nearly met their procurement targets. [5] By expanding energy storage capacity, this legislation ensures more efficient use of renewable energy, reducing strain on the grid and helping to stabilize electricity prices during periods of high demand. 

As we continue to expand renewable energy and modernize our grid, innovative green legislation in energy storage will be essential to overcoming the challenges of the Duck Curve and ensuring a reliable, sustainable future for America’s energy infrastructure.

The emergence of social media has impacted our mental health in a way more complex than we may understand for hundreds of years. U.S. Surgeon General Murthy has called for warning labels on social media to remind users that this has not been proven safe.[1] Further, adolescents who spend a significant amount of time online are at risk for anxiety and depression.[2] So, what about the companies behind these platforms? What liability do they have, if any, to the effects of social media on the general public?

Currently, there is an ongoing lawsuit by more than 40 states who are suing Meta, one of the largest operators of several social media platforms.[3] The claims under this lawsuit are that Meta is responsible for harmful features such as “recommendation algorithms, social comparison features, infinite scroll, notifications and alerts, and photo filters” which all have negative links to addictive behavior and mental health conditions, like body dysmorphia.[4] This lawsuit requests remedies such as fines, penalties, and orders to stop using some problematic features.[5] 

Additionally, there is litigation in one California court assessing the liability social media companies have about the potential effects on mental health.[6] The plaintiffs argue that failure-to-warn claims should be applied without a physical product at issue, and this would just be the law evolving to keep up with the times.[7] Opposing counsel argues this type of product liability is not applicable, since it tailors the experience to each user.[8] Similar lawsuits have been filed by parents, school districts, and attorneys general (AGs), claiming similar injuries.[9]

What About the Kids: 

This question is being challenged specifically on behalf of children, and the impact it has on their development. New York, California, and Utah have passed similar laws allowing parents to have greater control over their children’s algorithms and social media uses.[10] California’s law defines an “addictive feed as a website or app in which multiple pieces of media generated or shared by users are … selected or prioritized for display to a user based … on information provided by the user.”[11] 

TikTok’s defense to claims that it is misleading and threatening to adolescents is that they have already provided the safeguards necessary.[12] These protections include removing suspected underage users, “default screen time limits, family pairing, and privacy by default for minors under sixteen.”[13] The response from the New Jersey AG is that the safety features are misleading for parents, and the time restraints can be easily bypassed through passwords or eliminating the limit.[14] 

The ongoing litigation for liability in the social media space will set up future standards for how seriously we take threats to our mental health. The resolution of these legal challenges could set important precedents for accountability in the tech industry while balancing a First Amendment right to free speech on these platforms.
