5 viral – but problematic – TikTok tanning trends JR Culpepper June 2, 2026

With the days getting warmer, many are tanning or being outside more. Time in the sun is fun, as long as you protect yourself – and that usually means wearing sunscreen.

But some recent TikTok trends are discouraging people from using sunscreen. 

The sun’s ultraviolet, or UV, rays can be damaging, so sunscreen is essential to reducing the health risks of prolonged sun exposure, like skin cancer. 

Even if you already apply sunscreen regularly, check EWG’s 20th Annual Guide to Sunscreens to see whether your products provide adequate sun protection and are free from ingredients linked to health harms.

The guide includes thousands of sunscreen products and found nearly 80% of them do not meet EWG’s criteria for top-rated products, because they provide inadequate sun protection or contain harmful ingredients. 

Here are five viral sunscreen trends, the myths behind them, and how to stay safe from their potentially harmful effects.  

1. DIY sunscreen

Homemade sunscreen proponents say it’s a safe, affordable and simple option. But it may create more problems than it solves. DIY sunscreens often provide ineffective protection against UV radiation, since they almost always fail to achieve even a sun protection factor, or SPF, of 6.

2. “Base tans” and “Base burns” 

Some people avoid wearing sunscreen in order to build up a “base burn,” or tan. 

This is dangerous because any tan is evidence of skin damage – and sunburn is even more so. Tanning can increase your risk of skin cancer, even if you don’t burn. 

3. Sun “contouring”

This practice involves strategically applying sunscreen to some parts of the face, to enhance a tan in specific areas. Sounds great, right? Instant summerlong highlights and contours, achieved without makeup. 

But “sun contouring” is dangerous – it encourages people to damage their skin intentionally by applying lower SPF sunscreen to or leaving some parts of their face entirely unprotected.

The long-term effects of this method may ultimately make you look older. In addition to preventing sunburn, sunscreen prevents premature aging and reduces the risk of skin cancer. 

Instead of contouring your sunscreen, choose a contoured makeup look – and don't forget to apply sunscreen afterward

4. Sun tattoos

This is just a bad idea that requires you to overexposure your body to UV rays. 

If you develop skin cancer on one part of your body, it can spread to other areas of your skin and metastasize to other parts of the body. To reduce the risk of skin cancer, make sure to apply sunscreen everywhere your body will be exposed to the sun. 

5.  Treatment for acne

Tanning beds as a solution to skin problems? Not happening. 

In fact, tanning beds are classified as a known carcinogen – they can increase the risk of skin cancer. Research links the beds to a higher risk of melanoma, especially when first use occurs before age 30. 

The Food and Drug Administration has long warned that children and teens should never use tanning beds because of their health concerns. But the Trump administration quietly killed a pending FDA rule that would have banned anyone under 18 from using the beds.

Tips for sun safety

Here are a few tips to help you get the most out of your time in the sun. 

• Cover up and wear sunglasses. Shirts, hats, shorts and pants provide the best protection from UV rays. Good shades protect your eyes from UV radiation, which may cause cataracts.
• Find shade or make it. Picnic under a tree, read beneath an umbrella or take a canopy to the beach. Keep infants in the shade because they are still developing the tanning pigments, known as melanin, that protect skin.
• Wear sunscreen. EWG’s Annual Guide to Sunscreens evaluates the safety and efficacy of SPF-rated products, including sunscreens for recreational use and SPF-rated daily-use moisturizers and lip products. The best ratings are for products that provide broad spectrum protection formulated with ingredients that pose fewer health concerns when absorbed by the body. 

Getting outside for some sun is good for you – in moderation. Just ignore the fleeting trends and stick to the tried and tested: Wear sunscreen to protect yourself, and wear it daily.

EWG’s mission in the 20 years we’ve produced the Guide to Sunscreens has been to ensure that whenever you use sunscreen, the SPF products you trust to protect your family are free from ingredients of concern, backed by science and effective at reducing the effects of UV radiation.

Responding to a new warning from the World Meteorological Organization (WMO) that El Niño conditions are strengthening and likely to drive more extreme weather in the coming months.

Anne Jellema, Executive Director of 350.org, said:

El Niño is a naturally occurring climate pattern , but its impacts are now being intensified by human-driven climate change caused by burning fossil fuels. As global temperatures rise, El Niño events are becoming more dangerous, amplifying heatwaves, floods, droughts and wildfires, and putting lives and livelihoods at greater risk around the world.

El Niño is not new , but the conditions we are experiencing today are. Fossil fuel pollution is loading the dice, turning a natural climate cycle into a far more dangerous force. Now is the time to prepare. But preparedness alone is not enough. We must urgently tackle the root cause by phasing out fossil fuels and holding polluters accountable.

A permanent windfall tax on fossil fuel companies could help countries protect lives and livelihoods as climate impacts intensify. This is also a moment for global cooperation , because no country can face this crisis alone.”

350.org is calling for urgent global action to rapidly phase out fossil fuels, scale up support for climate adaptation, and ensure those most responsible for the crisis contribute to the solutions.

In a school in South Africa, a group of students stare at a row of small plants growing in a greenhouse. Each one is involved in the lesson, caring for the growing crops.

But this is no ordinary classroom setting. These children are learning about aquaponics, a method of growing plants and fish in a mutually beneficial water system. This ancient technique of food production is now being taught to millions of schoolchildren after being introduced by the South African government seven years ago.

Laerskool Kempton Park on the edge of Johannesburg was one of the first schools to introduce the subject with the aim of improving food security. This is a serious challenge in a country where an estimated 19.7 million people, or around 30% of the population, experience moderate levels of food insecurity, meaning that they struggle to afford enough food for a healthy, balanced diet.

Bringing the farm to school

Aquaponics is a way of supporting communities to access food in a sustainable and efficient way. The solution is simple: fish waste is turned into available nutrients by bacteria in the water. Plants absorb these nutrients and the cleaned water is returned to the fish tank.

There are multiple benefits to this approach. The system doesn’t require chemical fertilisers, soil or large tracts of land. It is also highly efficient, with recirculated water being used over and over again. This is an important feature in areas of South Africa that experience drought or unpredictable weather.

Agricultural subsidies can be repurposed for a just and sustainable rural transition

Aquaponics can offer a range of benefits depending on the local context. In South Africa, townships in major cities such as Johannesburg don’t always have the space to produce their own food, while in other places, such as the Northern Cape, extreme weather is making agriculture much harder.

At Laerskool Kempton Park, the students have benefited from the innovative work of INMED, a non-profit organisation that supports vulnerable children and families in the country. 

INMED has trained hundreds of teachers and over 7,000 children on the benefits of aquaponics. With the help of funding from the Adaptation Fund through the UNDP-Adaptation Fund Climate Innovation Accelerator (AFCIA), the organisation was able to develop its own aquaponics system to be used in schools.

Scaling up the solution

INMED describes its prototype as a ‘plug and play’ system, designed to be modular and easy to install and manage. The system includes a 2,000-litre fish tank powered by a solar pump to circulate water. The design is simple with a view that it could be easily replicated across different school settings.

Unathi Sihlahla, director at INMED South Africa, told Climate Home News that “aquaponics speaks to a number of challenges… including limited access to nutritious food, high youth unemployment, water scarcity, and in many cases, poor or no access to arable land.” 

Giving nature breathing room builds climate resilience

INMED’s prototype allows communities to work around these problems as it doesn’t need soil and uses far less water than conventional agriculture.

“We’ve seen schools that previously had no food production now able to grow vegetables consistently, while also producing fish. That food often goes straight into school meals or supports vulnerable households nearby,” Sihlahla added. The project estimates that over 5,300 kilogrammes of food have been harvested in each quarter the system has been operating.

As aquaponics is now part of the school curriculum, many educational departments across South Africa have been looking at ways to teach the subject. INMED’s innovative design could provide a handy solution. The organisation has already started to roll it out across different provinces and a new collaboration with the Eastern Cape Provincial Department of Education is in the works. INMED is also scaling the ‘plug and play’ model in Tanzania.

For educators, teaching schoolchildren new agricultural skills is not only about improving food security, but also about creating the next generation of farmers. This group will need to grow food with the increased threat of extreme weather events and having knowledge of alternative methods, such as aquaponics, could be key.

“Agriculture is not seen as something young people want to go into, but when they are exposed to something like aquaponics, it feels modern and relevant,” said Sihlahla, adding that some students have started their own projects at home or are looking to continue studying the method.

“There’s also a sense of pride. Producing food that supports your school or community changes how young people see themselves and their role.”

Engaging the next generation

The Adaptation Fund’s support for young people extends beyond South Africa. Several other related projects aim to equip youth with practical skills for climate adaptation.

In Costa Rica, a $10-million project implemented by private foundation Fundecooperación included several creative youth-focused programmes in climate-vulnerable areas. It trained young people in coral reef restoration and farming techniques, involved high school students in community water resource monitoring and management, shared knowledge on adaptation through a theatre tour in schools, and created an art mural competition using AI. 

Extreme heat is rewriting food security. The best fixes are already within reach

In Lesotho, meanwhile, climate education is being integrated into the school curriculum through climate-smart agriculture materials and teacher training rolled out across primary and secondary schools. This is equipping students from an early age with practical, locally relevant knowledge to build resilience. 

“Children and young people are among the most vulnerable to climate change,” said Mikko Ollikainen, head of the Adaptation Fund. “These programmes are not only training young people in adaptation but empowering them.”

Just as Colombia – a coal-producing country that has halted new exploration licenses for hydrocarbons – was set to host the first fossil fuel phase-out summit in late April, the government received notice from a foreign energy firm operating on its soil. It was being sued for millions of dollars.

One day before Colombia hosted representatives from around 60 countries for the first Global Conference on Transitioning Away from Fossil Fuels, Spain-based firm Termocandelaria Power, which operates two of the country’s diesel- and gas-fired power plants, sued the government for $198 million alleging a breach of investor protection rules under a bilateral agreement.

Termocandelaria said government measures since 2024 have prevented its Colombian subsidiaries from receiving full payment for the power they supplied to a public utility, while the Colombian government justified its actions as needed to guarantee financial solvency and deliver electricity to rural communities.

While Termocandelaria declined to comment for this article, the company said in a press release last month that investment protection treaties “are designed to provide a stable and predictable legal framework for long-term investments in strategic sectors”.

The timing shows how trade agreements that offer investors protection when government decisions are seen as causing harm to their business – a system known as investor-state dispute settlement (ISDS) – can hamper the transition away from fossil fuels even when countries are pushing for it. Governments in the Global South are particularly exposed, experts told Climate Home News.

As part of the official academic contribution to the Santa Marta conference, researchers recommended that governments should “recognise” ISDS as a barrier to the energy transition, and called for negotiations on an international initiative to dismantle ISDS protection for fossil fuel investments, either through “a new standalone” international agreement or as part of a broader treaty.

Mario Osorio, a research fellow at the Center for Economic and Policy Research (CEPR), said Termocandelaria’s claim against Colombia “puts in perspective how serious, concrete and real these threats are” for developing countries.

Osorio said the second fossil fuel transition conference – to be held next year in Tuvalu – presents an opportunity for advancing ISDS reform from discussion to “something more concrete”.

ISDS is a mechanism in international trade that allows foreign corporations – many of them linked to fossil fuel interests – to sue governments in international arbitration courts. One 2022 study estimated that possible legal claims from fossil fuel investors could reach $340 billion.

In the lead-up to the Santa Marta conference, Colombian President Gustavo Petro pledged to exit the ISDS system by reviewing Colombia’s 129 investment protection agreements. This came after more than 200 economists sent Petro an open letter urging Colombia to abandon the ISDS system.

Eunjung Lee, a senior policy advisor at UK-based think-tank E3G, said the Santa Marta conference had helped elevate ISDS reform as a key element of the transition away from fossil fuels, despite the issue remaining relatively little-known, even among climate negotiators.

She added that governments tend to be cautious about discussing ISDS at climate summits, as these treaties also implicate trade and economy ministries. “If it is not your file, then you can’t really say much about it and taking action is not necessarily up to you,” she explained.

Kyla Tienhaara, Canada Research Chair in Economy and Environment and a professor at Queen’s University who has worked on the issue for two decades, said the conference in Santa Marta marked a new approach, and that Colombia had placed ISDS “prominently in the agenda”.

The next transition conference presents an opportunity for governments to land on something more practical, particularly under the agreed work stream on “macroeconomic dependence and financial architecture”, but it will depend on the co-chairs Tuvalu and Ireland, she said.

Ireland was sued in May by oil company Lansdowne for failing to award a lease in the Barryroe offshore field. The claim was made under the Energy Charter Treaty (ECT), which fossil fuel companies have used to sue several governments over the consequences of enacting their climate policies.

Following a similar move by some other European states, Ireland left the ECT in April while the Santa Marta conference was ongoing, but existing fossil fuel investments are still protected for 20 years under a “sunset clause”.

“Disappointing” conference report

Despite the prominence of the issue in the conference rooms, experts told Climate Home that the chairs’ takeaways report was “disappointing”, as it did not explicitly mention ISDS as a key obstacle to the energy transition.

The Netherlands, which co-hosted the summit, may have faced conflicting interests, said Tienhaara, as it is second only to the US as a “home state” for the investors bringing the most ISDS cases, including foreign companies structuring their investments through the country.

The Dutch government also withdrew from the ECT last year, which means it understands and has acted on the threat of investment treaties to climate action, the researcher said. “Unfortunately, they seem unwilling to extend their concern to the harm that these treaties cause in other countries, particularly in the Global South,” she added.

Lee of E3G said Global North countries like the Netherlands tend to export capital to developing countries, which is why they seek to protect their investors’ interests and are unlikely to drive a dismantling of the ISDS system themselves.

Developing countries like Colombia, which have been negatively affected by ISDS claims, have an incentive in “voicing their concerns” and forming a bloc around this topic. “Uniting Global South countries can make a stronger case,” Lee said.

Today, Montana conservation organizations challenged the U.S. Forest Service (USFS) and U.S. Fish and Wildlife Service (USFWS) for dramatically weakening a core benchmark for grizzly bear conservation in Montana’s Helena-Lewis and Clark National Forest. The lawsuit targets the agencies’ approval of the Larabee Hat Vegetation Project—a large-scale logging and road-building project—for abandoning the science on grizzly bear conservation to obscure the project’s significant impacts to the species.

On behalf of Native Ecosystems Council, Alliance for the Wild Rockies, and the Council on Wildlife and Fish, the Western Environmental Law Center filed the lawsuit in the U.S. District Court for the District of Montana this morning.

The challenge centers on how the agencies define “secure habitat” for grizzly bears—areas free from roads and human development large enough for a bear to safely meet its daily foraging needs. For decades, science has established that secure habitat patches must provide an individual female grizzly adequate space to forage for 24-48 hours without crossing or nearing motorized routes. The scientific community agrees grizzly bears need thousands of acres to meet these daily needs.

USFS and USFWS followed the scientific consensus and used a 2,500-acre minimum secure habitat patch size when they approved the Helena-Lewis and Clark National Forest’s Forest Plan in 2021. But in April 2025, USFWS quietly reversed course, redefining “secure habitat” outside the Northern Continental Divide Ecosystem (NCDE) grizzly recovery zone as patches of just one acre. USFS followed in May 2025, updating its internal guidance to match.

“There is no scientific support for one-acre ‘secure habitat’ patches,” said David Woodsmall, attorney at the Western Environmental Law Center. “The agencies simply redefined the problem away. A one-acre island of forest surrounded by roads isn’t secure habitat—it’s a death trap for a bear trying to survive there. Federal land managers must follow the law, even under the Trump administration, and pulling policy changes like this out of thin air is clearly outside the law.”

The stakes extend well beyond this single instance. The Larabee Hat project sits in the Divide Geographic Area, part of the only public lands corridor connecting the NCDE and Greater Yellowstone Ecosystem (GYE) grizzly bear recovery zones. Genetic exchange between these two isolated populations is considered essential to grizzly bear recovery in the contiguous U.S.

“The adverse cumulative impacts of this project would be devastating to wildlife and wildlife habitat, native plants, and aquatic species, which demonstrates why this project generates absolutely no net public benefit,” said Steve Kelly with Council on Wildlife and Fish. “It makes no ecological or financial sense to degrade irreplaceable, untrammeled native forest into failed tree plantations and marginal pastureland for subsidized livestock at great taxpayer expense.”

The project proposes logging on nearly 17,700 acres, including 1,266 acres of clearcuts, more than 1,850 acres of other timber harvest, and 16.8 miles of new temporary roads over the next 15 to 20 years.

Under the old 2,500-acre definition, the Divide Geographic Area contained approximately 41,531 acres of secure habitat. Under the new one-acre definition, that number jumps to 59,143 acres—an artificial increase of more than 17,000 acres that makes the landscape appear far healthier for bears than it actually is.

“We won a court case on a similar issue last year in which the Forest Service and Fish and Wildlife Service tried to shrink the definition of secure habitat for grizzlies from 2,500 acres to 10 acres, which is ridiculous for these wide-ranging bears,” said Mike Garrity, executive director of the Alliance for the Wild Rockies. “The Judge said in the ruling: ‘In relying on a 10-acre patch size to define grizzly bear secure habitat in the absence of any scientific evidence showing that such acreage provides adequate habitat, the Fish and Wildlife Service failed to use the ‘best available science’ in violation of the Endangered Species Act,’ adding ‘grizzly bears in other ecosystems have been found to need upwards of 2,500 acres of secure habitat.’”

“Here, the Helena-Lewis and Clark National Forest secretly shrunk grizzly bear secure habitat to one acre in size without telling the public,” Garrity continued. “The Larabee Hat project area is in an important corridor for grizzlies from the Northern Continental Divide Ecosystem to connect with grizzlies from the Greater Yellowstone Ecosystem.  For grizzlies to be delisted, they once again have to have one connected population in the Northern Rockies with secure habitat.”

“Changing the parameters of what qualifies on paper as habitat doesn’t make more habitat,” said Sara Johnson Ph.D., a wildlife biologist for the Forest Service for 14 years. “It just makes it easier to approve more logging and more roads while ignoring the real consequences for grizzly bears. The law doesn’t allow it, and we will apparently have to be the people who say ‘no.’”

This case builds directly on a successful 2025 legal challenge, in which a federal court struck down a similar attempt to shrink grizzly bear secure habitat patch size on the Custer-Gallatin National Forest, finding the approach scientifically unjustified and harmful to bears in fragmented landscapes.

“The court already rejected this approach once,” said Woodsmall. “These agencies are trying the same thing again in a different forest. We intend to stop it again.”

Lo que antes se consideraba un sueño de idealistas,  «basura cero» es ahora una corriente dominante. Incluso ha entrado en el lenguaje de la ONU: el organismo elaboró una resolución en la que instaba a los gobiernos a «promover iniciativas basura cero», estableció un Día Internacional Basura Cero y creó un Consejo Asesor Basura Cero; además, el PNUMA, ONU-Hábitat y otros organismos de la ONU utilizan el concepto en campañas e informes. Este año, basura cero fue nombrado una de las principales prioridades de la Agenda Global de Acción Climática. La Fundación Basura Cero de Turquía, uno de los principales promotores de estos esfuerzos, está organizando su segundo Foro Global Basura Cero bajo el lema «Camino a Antalya: basura cero como acción climática». Turquía será la anfitriona de la COP31 sobre el clima.

Si bien este avance es emocionante, las palabras importan. Cuando los mismos organismos de la ONU que se supone deben promover basura cero reconocen las plantas de incineración de residuos para generar energía y la reutilización de las cenizas volantes altamente tóxicas de los incineradores como una solución basura cero, significa que algo anda mal. Del mismo modo, cuando Pakistán afirma que busca una economía “basura  cero” al aumentar la capacidad de conversión de residuos en energía, las alarmas suenan entre los defensores de basura cero en todo el mundo: la incineración es un oxímoron para basura cero. Lo que nos muestran estos ejemplos es que es necesario adoptar y defender enérgicamente una verdadera definición de basura cero.

¿Qué es basura cero?

El concepto «basura cero» surgió hace 30 años al adaptar objetivos de fabricación como el de «cero defectos» a los residuos sólidos. Basura Cero es tanto una visión como un plan de acción. Como plan de acción, incluye estrategias para eliminar la idea de «basura»: prevención de residuos, rediseño, reutilización, cambios en los patrones de consumo, reciclaje, compostaje y otros métodos para re procesar la materia orgánica. Basura Cero se guía por el objetivo de reducir progresivamente el vertido en vertederos e incineradoras, un criterio para juzgar la eficacia de los programas y políticas de residuos.

Como visión, su objetivo final es cambiar la forma en que producimos, consumimos y procesamos los desechos para que nuestra economía de materiales se ajuste a los límites planetarios. Esto no solo se refiere a los materiales, sino a nuestra relación con ellos, con el medio ambiente y entre nosotros. Es por eso que «basura cero» tiene sus raíces en la justicia ambiental: apoya el florecimiento de todos, independientemente de la raza, la clase o cualquier otra identidad, y los derechos de la naturaleza. Los sistemas basura cero se basan en la comunidad, reconocen a los recolectores de residuos como trabajadores, eliminan las «zonas de sacrificio» que suponen una carga desproporcionada para las comunidades pobres y marginadas, y sitúan a las personas en el centro de las soluciones.

Esa es la belleza del sistema basura cero: ofrece una alternativa alentadora a un sistema lineal que perpetúa la eliminación, el agotamiento de los recursos, el cambio climático y la contaminación que amenazan la salud pública y el bienestar. No sucederá de la noche a la mañana, pero establece una dirección clara.

Defender basura cero

Existen múltiples debates dentro del movimiento ambientalista sobre la cooptación del concepto basura cero. ¿Debemos dejarlo pasar? ¿Defenderlo? Hay argumentos sólidos en todos los lados de la mesa. Pero nuestro objetivo es expandir el verdadero basura cero a nivel mundial. La generalización significa que las ideas se aceptan como normales porque la mayoría de la gente las comparte; eso es por lo que miles de comunidades, funcionarios gubernamentales y empresas han trabajado durante décadas. Luchar contra esta apropiación es, por lo tanto, una parte inevitable de la generalización.

Cada vez que se presenta un proyecto de conversión de residuos en energía o de plásticos en combustible como «basura cero», las autoridades en la materia deben aclarar las cosas. La incineración de residuos para generar energía perpetúa la generación de residuos porque requiere materia prima para quemar, compite con la reutilización y el reciclaje por materiales de alto poder calorífico, depende de materias primas de origen fósil como los plásticos, produce emisiones de gases de efecto invernadero y genera residuos peligrosos. Nada de eso podría estar más lejos del concepto basura cero.

Lo más importante es que el concepto basura cero no es solo un concepto abstracto.

Durante más de tres décadas, cientos de ciudades, miles de comunidades y muchos profesionales del sector de los residuos han liderado la transición hacia él. Han demostrado que es posible lograr más del 90% de separación en origen, tasas de desvío del 80% o más, mejores condiciones de trabajo para los recolectores de residuos y economías locales basadas en la reparación y la reutilización. También demuestran que seguir la jerarquía de residuos crea más empleos, reduce más las emisiones de metano y mejora la salud pública.

Facilitar la implementación de la iniciativa «basura cero» 

En los últimos años, más gobiernos, instituciones financieras, universidades y profesionales del sector de los residuos han adoptado la visión «basura cero» y han priorizado las medidas en las etapas iniciales por encima de la eliminación. Eso es alentador, pero se necesita mucho más. Por ejemplo, solo el 1 % de la financiación internacional destinada a la reducción de metano en el sector de los residuos se destina a estrategias «basura cero», como el compostaje.

Si los bancos multilaterales de desarrollo y otras instituciones financieras internacionales destinaran el 99 % restante, en lugar de a sistemas nocivos de tratamiento final como incineradoras y megavertederos, a la prevención y recuperación de residuos orgánicos a nivel comunitario, se nivelaría el campo de juego: habría más incentivos para un cambio en los patrones de producción y consumo, y los gobiernos locales y las comunidades acelerarían la transición hacia basura cero. Si los gobiernos que afirman perseguir basura cero actuaran en consecuencia, liderarían la transición e inspirarían a otros.

Los organismos de la ONU, como el PNUMA, ONU-Hábitat y el Consejo Asesor Basura Cero, tienen la responsabilidad especial de establecer una visión clara para los gobiernos y las instituciones, y promover una agenda auténtica basura cero para impulsar la sostenibilidad ambiental, la equidad social y los sistemas económicos que respeten los límites naturales.Mientras continuamos trabajando hacia un futuro basura cero, honremos su verdadero espíritu, que impulsa el cambio de los sistemas. Y apoyemos y ampliemos los programas y políticas de eficacia probada que los gobiernos, las comunidades, los recolectores de residuos, las ONG y las empresas están sosteniendo. Protejamos el término y honremos la práctica: pongamos en práctica el verdadero basura cero.

President Trump Revokes Executive Orders Protecting Public Lands from Unmanaged Motorized Recreation  Repeal threatens wildlife, public safety, and outdoor recreation across federal lands

Laura Peterson, Senior Attorney, Southern Utah Wilderness Alliance (SUWA); (801) 236-3762; laura@suwa.org

Washington, D.C. – Last Friday, after most people left work for the weekend, President Trump announced the repeal of two executive orders (11644 and 11989) that govern off-road vehicle (OHV) and over-snow vehicle (OSV) use on public lands. He further directed federal land management agencies to rescind or revise their regulations implementing these orders, risking chaos and confusion on public lands across the country. 

For 54 years, these orders have helped protect streams, wildlife and their habitats, and opportunities for safe recreation by providing clear and consistent guidance for motorized and nonmotorized users on Bureau of Land Management, U.S. Forest Service, and National Park Service lands. In response, numerous conservation organizations cried foul over this latest attack on public lands. 

Below are quotes and background information:

“These executive orders provided the foundation for common-sense management of motorized vehicles on public lands, recognizing the detrimental impact unmanaged motor vehicles have on cultural sites, wildlife, waterways and other public land users,” said Laura Peterson, Senior Attorney at the Southern Utah Wilderness Alliance. “In Utah alone, there are tens of thousands of miles of dirt roads and trails open to motorized vehicles. Far from motorized vehicles being kept out of public lands, it’s quite the opposite: it’s the wildlife and visitors trying to picnic or camp with their families that are being chased out at every turn. The impacts of repealing these executive orders will be long-lasting and devastating.” 

“Removing or weakening regulations for properly managing motorized recreation will endanger at-risk fish and wildlife, particularly grizzly bears and bull trout, because off-road vehicles choke streams with dirt and damage sensitive habitats,” said Adam Rissien, rewilding manager with WildEarth Guardians. “Today’s off-road vehicles are even more powerful, more damaging than when the first orders were put in place to protect public lands from unfettered motorized recreation, and removing long-standing protections will only make matters worse.” 

“Nobody wants national parks damaged by off road vehicles. The administration is making sweeping changes that could throw open the doors to unchecked off-road vehicle use that puts at risk the very resources national parks were created to protect,” said  Cory MacNulty, Southwest Region Campaign Director for the National Parks Conservation Association (NPCA). “With thousands of miles of roads and trails across public lands already open to off-road vehicles, what is at stake here is not access – it’s the future of the places that Americans love most.”

“Public lands are big enough for hikers, hunters, horseback riders, mountain bikers, motorized users and families looking for quiet places to camp, if we are wise about how we share them,” said Alison Flint, Acting Vice President for Federal Policy at The Wilderness Society. “For more than 50 years, common-sense safeguards have helped land managers reduce conflicts, protect clean water and wildlife habitat, and make sure public lands can be enjoyed by everyone. This administration is working to destroy this foundation, which has been in place since Richard Nixon. This is a cynical attempt to pit public land users against one another while weakening the rules that protect the land itself. Our children and grandchildren deserve public lands that are healthy, shared and cared for—not places where decades of balanced management are tossed aside for special interests.”

“The intent of these executive orders was to minimize environmental damage and user conflict from motorized vehicle use (including snowmobiles) on public lands,” said Anneka Williams, Winter Wildlands Alliance Policy Director. “They were established in the 1970s in response to widespread and increasing off-road vehicle use on public lands to balance motorized and non-motorized recreation and protect natural ecosystems and wildlife. Without these orders, there is no guidance to minimize impacts from motorized recreation, a loss that will have lasting consequences for decades to come.” 

 “This rescission is yet another loss for wildlife and natural places,” said Vera Smith, director of national forests and public lands for Defenders of Wildlife. “Removing common-sense tools for managing all-terrain vehicles, dirt bikes and other off-road vehicles on public lands is reckless and nonsensical.”

“If you want to make the public land experience worse for everyone – motorized and non-motorized – blowing up travel management is a good place to start,” said Hilary Eisen, federal policy director at Wild Montana. “It’s how we keep public lands working for everyone. These EOs are the foundation land managers rely on to provide motorized access while protecting wildlife, natural resources, and opportunities for quiet, non-motorized recreation. Getting rid of them to satisfy a tiny minority of users just invites more use conflict, makes public lands more dangerous, and degrades public lands and waters. This is a reckless move that could set off a chain reaction that undermines everything we love about our public lands.”

“Recreationists of all types enjoy camping next to clean mountain streams, seeing wildlife, and enjoying the great outdoors with their friends and family. Public lands managers have relied on the previous executive orders to protect water quality, ensure wildlife have space to roam, and preserve high-quality recreation opportunities for everyone,” said John Robison, public lands and wildlife director at the Idaho Conservation League. “If agencies no longer have to minimize the impacts of motorized recreation to water quality, wildlife, and other recreationists, we are in danger of degrading the very values of our public lands that draw us there again and again. In the end, everyone will be worse off.” 

“Loud engines stress wildlife, displacing them from feeding and breeding areas. Tire damage speeds erosion and harms ecosystems,” said Chris Bachman, Conservation Director at the Yaak Valley Forest Council. “Vehicle tires and undercarriages carry seeds into forests and grasslands, disrupting natural systems and food resources. The Roadless Rule has been rescinded, and every effort is being made to weaken the Endangered Species Act. Now this? This administration appears determined to cause significant harm to our public lands at every turn.”

“As we see in nature, balance needs to be our rule. More and more we are seeing the scales of regulation be tipped wildly in one direction, towards extraction and deregulation of public lands,” said Allison Weber, Policy Director for Friends of the Inyo. “We support the protection of ecosystems and species, and we know that regulation of various activities on public lands are necessary to achieve that goal, to obtain balance between natural and recreational values. Deregulating recreation like OHV use ultimately leads to degradation of the landscapes and the routes themselves, followed by additional labor and money by our public lands agency staff to restore them to working order. If we want to all enjoy these landscapes for years to come, we are moving in the wrong direction.”

“This executive order puts America’s wild places at risk by prioritizing motorized vehicle access over the protection of wildlife, clean water, and public lands. For decades, commonsense safeguards have helped land managers balance motorized recreation with conservation and other types of recreation, ensuring that public lands remain healthy and accessible for everyone,” said Athan Manuel, Director of Sierra Club’s Lands Protection Program. “Eliminating responsible motorized management threatens fragile habitats, increases damage to sensitive landscapes, and undermines the experiences of people seeking quiet recreation in nature. America’s public lands belong to all of us, and future generations deserve the chance to experience wild and thriving places. Instead of weakening protections, we should be strengthening our commitment to conserving the natural heritage that makes these lands so special.”

“For decades off-road vehicles have had an outsized impact on BLM-managed lands and that’s especially true today as faster and louder vehicles blanket the landscape,” said retired BLM Director Jim Baca. Baca served as BLM Director from 1993-94. “ORVs harass wildlife, degrade streams and destroy cultural sites, and are generally a nuisance to other public land visitors. BLM has struggled mightily to control this use and its job has only gotten harder under Trump’s second term as career BLM personnel have been fired and the agency’s budget decimated. Trump’s latest Order – undoing Nixon and Carter-era Executive Orders that directed BLM to ‘minimize’ the impacts these vehicles have on public lands and resources – is only going to make BLM’s job harder at a time when it needs to be doing more than ever to rein in this activity.” 

“Without proper management, off-road vehicles tear up vegetation, disrupt wildlife, damage streams, and lead to conflicts among recreational users,” said Thomas Delehanty, attorney at Earthjustice. “President Trump is discarding the long-standing, common-sense framework for managing off-road vehicle use to cater to a narrow set of interests. Our public lands, streams, and wildlife will pay the price.”

Background

In response to the growing use of dirt bikes, snowmobiles, all-terrain vehicles, and other off-road vehicles (ORVs), and corresponding environmental damage and conflicts with non-motorized users, Presidents Nixon and Carter issued Executive Orders 11644 and 11989 in 1972 and 1977, respectively. These executive orders require federal land management agencies to plan for ORV use to protect resources and other recreational uses. Specifically, the executive orders require that, when designating areas or trails available for ORV use, the agencies locate them to: 

(1) minimize damage to soil, watershed, vegetation, and other resources of the public lands; 

(2) minimize harassment of wildlife or significant disruption of wildlife habitats; and 

(3) minimize conflicts between off-road vehicle use and other existing or proposed recreational uses of the same or neighboring public lands.

Do electric vehicles almost always have a lower carbon footprint than gasoline-powered cars?

The EPA, IPCC, and many independent studies have found that electric vehicles have lower lifetime emissions than gas-powered vehicles in nearly all cases.

“Lifetime” calculations include emissions released during EV manufacture, as well as the generation of electricity used to charge the car. An average 300-mile range EV produces less than half the lifetime emissions of a conventional 30 miles per gallon car.  

This is mainly because EVs are significantly more energy efficient than gasoline cars: over 77% of electricity input is converted to power at the wheels, compared to a conversion of 12-30% of energy in gasoline to wheel power. Meanwhile, the lack of tailpipe emissions offsets an electric sedan or SUV’s initial manufacture emissions within just 1.5-2 years of regular use.

As the U.S. power grid becomes increasingly renewables-based, EVs’ emissions superiority vis-a-vis gas-powered vehicles will continue to grow.

A new report from National Nurses United finds that three major Catholic hospital systems have spent the last decade leading the health care industry in the closures of pediatric care units. Among the country’s ten biggest hospital chains, three Catholic systems (Ascension, CommonSpirit, and Trinity) shuttered pediatric units at the highest rates of any major systems.

Nurses from National Nurses United will protest in St. Louis on June 3. Nurses first plan to protest outside the district office of U.S. Representative Wesley Bell to call on him to return and refuse campaign contributions from Palantir and American Israel Public Affairs Committee (AIPAC).

The dose makes the poison – but there’s more to the story Anthony Lacey June 2, 2026

Does the dose define how chemicals can lead to harm? Yes.

But is the dose the only thing that “makes the poison”? No. 

The idea that the dose makes the poison – originally explained as “all things are poison, and nothing is without poison; only the dose permits something not to be poisonous” – was introduced by a 16th-century physician named Paracelsus. It laid the foundation for what is, more than 400 years later, the field of toxicology.

Today the chemical industry and its supporters point to the phrase when claiming health risks only exist above certain chemical exposure levels and some doses are “too low” to be harmful.

It’s generally true that a chemical is more toxic at higher doses. But our understanding of how chemicals and mixtures interact with our bodies has improved considerably over the past 400 years, showing that there’s more to consider than just the amount of a substance.

A complicated mix of factors affect the ‘poison’

Who you are, when and how often you are exposed to something, and what else you’re exposed to all matter. And what is defined as a low dose might, with prolonged exposure, be sufficient to lead to health harms.

Relationships between dose and biological response – how it impacts a body – can be linear, where a higher dose results in a greater response. But scientists have also observed a variety of other, non-linear relationships between dose and response. Depending on the chemical, a higher dose doesn’t necessarily mean a higher response, or more “poison.”

In some cases, both lower and higher doses can trigger certain health harms, while moderate doses do not (see Panel F in Figure 1 below). For other chemicals (like in Panel D), the relationship might be logarithmic, meaning that toxicity might drastically increase at lower dose-ranges but taper off as doses get higher.

What does ‘dose’ even mean?

The dose is the amount of a substance that is absorbed into the body. But not everything that we come into contact with will be absorbed into the body. 

The exposure route can play a large role. 

For example, titanium dioxide is an effective active ingredient in sunscreens, an ultraviolet filter that does not cross the skin barrier when applied. But its use in sprays or powders raises concern, since the particles can be inhaled deep into the lungs and harm health. 

So the impact of exposure isn’t just about the amount, it’s also about how a person is exposed. 

What else matters, apart from the dose?

When you are exposed 

Low exposures in utero or during early childhood can have very different effects than the same exposure in adulthood. Even when they’re exposed to the same amounts of a chemical, children may absorb more than adults. 

A World Health Organization study found young children can absorb up to five times more lead than adults from the same ingested dose. 

And even if the dose is the same, it could have a greater impact on kids than adults because their brains are still developing. They may suffer irreversible damage to the brain and experience developmental impacts later in life. 

What else you are exposed to

We know we aren’t exposed to chemicals one by one but instead to mixtures of chemicals over long periods of time. We constantly come into contact with combinations of chemicals from food, water and consumer products. 

Research shows that small, seemingly insignificant doses of multiple chemicals can add up or interact together to multiply each other’s effects, creating a total health risk that is measurably more harmful than those from the chemicals acting alone.

Glyphosate, an herbicide, and cypermethrin, an insecticide, are sometimes used together to manage crops. A 2025 study compared the impacts in cells of individual exposures to glyphosate and cypermethrin with exposure to both pesticides at the same time. The authors found that joint exposure triggered early and late cell death, along with overall toxicity in animal models.

When combined, these two pesticides triggered more late cell death than would be expected from simply adding their individual effects together. A decade earlier, another study reported the same pattern – that these chemicals magnify each other’s effects when mixed.

Both pesticides are frequently used together on soy and corn fields, so this mixture analysis is a simulation of real-world exposures.

In 2021, the European Commission and European Food Safety Authority, or EFSA, announced a joint strategy to integrate cumulative risk assessments in pesticide reviews. This new approach incorporates methods to assess the effect of chemical mixtures on human health. EFSA is reviewing the status of multiple approved pesticides in light of toxicity findings from mixtures assessments. 

U.S. regulatory safety assessments routinely fail to account for chemical interaction, when the presence of one chemical can unexpectedly amplify the toxicity of another by altering how much is absorbed or metabolized. 

The bottom line: It has been known for a while that exposure to chemicals in combination can multiply their effect. In other words, for some chemical mixtures, the sum is greater than its parts. 

How often you are exposed 

The average person uses between 10 and 14 personal care products a day, spanning several categories. You aren’t exposed just once, you’re exposed every day for years. 

This repeated, long-term use leads to what’s called cumulative exposure. While many chemicals are rapidly excreted, they can still have an impact with repetitive low dose exposure. 

The issue isn’t just a single dose today. It’s repeated exposure – even at low levels – across months or years that can add up.

Who you are

Individual susceptibility, genetics, and your microbiome matter. 

Your genes can act like a personalized instruction manual for how well your body processes toxins. Some people have versions of enzymes that clear chemicals quickly, while others can have versions that allow the same small dose to build up to dangerous levels.

Your immune system and gut microbiome can also change how you respond. A “safe” dose of a given substance could be “poison” to an immunocompromised individual or someone taking a specific medication.

Statins, widely used cholesterol medications, are broken down in the body by an enzyme called CYP3A. Grapefruit juice contains compounds called furanocoumarins that stop CYP3A from doing its job. 

So when ingested with grapefruit, more of the drug can be absorbed than intended. Both substances alone are safe, but the combination can be unexpectedly toxic. This is why some medications warn about consuming grapefruit while taking the medicine.

Some medication labels warn against consuming grapefruit when taking the drugs

The case of hormone disruptors 

Endocrine-disrupting chemicals, or EDCs, are a class of chemicals that mimic the body’s natural hormones. Our hormone system is designed to respond to tiny “doses” of substances that act as signals to control how we grow and how our bodies use energy.  

One well-known EDC is bisphenol A, or BPA. Results from a 2012 study linked low doses of BPA, legally considered “safe,” to endocrine disruption. 

The study emerged from a partnership among the Food and Drug Administration, the National Institute of Environmental Health Sciences, and 14 independent researchers, called CLARITY-BPA. 

As a landmark 2007 report in Environmental Health News notes, even exposure to a tiny dose of an EDC can interfere with these signals. Repeated exposure over time can cause health impacts later in life.

The relationship between the amount of an EDC and its effect on health doesn’t always proceed in a straight line or in one direction. When the relationship doesn’t move in one direction only – when the shape of the dose-response relationship does not consistently increase or decrease – the low-dose effects of exposure to EDCs “cannot be predicted by the effects observed at high doses,” one study found.

This study’s results demonstrate how, if only high doses are tested, serious health impacts that only show up at lower doses can be missed. 

The researchers tested a cancer-causing chemical called TCDD on rats. At a “high dose” of 0.25 micrograms per kilogram, or µg/kg, TCDD didn’t seem to cause any reproductive problems. But when the dose was tested at a much lower level, 0.064 µg/kg, researchers saw a significant drop in the rats’ daily sperm production.

This doesn’t mean that higher doses are safer. The authors point out that high levels of TCDD are still harmful to many organs and can even be deadly. Instead, the study shows why we can’t just say “the dose makes the poison.” Low levels of exposure can interfere with the body in ways that are not seen at high doses.

Low doses do not mean safe doses

Analysis of the science documents made public through trial discovery led to EWG advocating for increased regulation of the “forever chemical” perfluorooctanoic acid, or PFOA. At the time, PFOA was extensively used as a processing aid in the manufacturing of Teflon.

But industry representatives pushed back, citing the notion that dose makes the poison to argue that health concerns about PFOA were “unfounded.” PFOA detections were “negligible … and within government standards,” they said, characterizing the measured average PFOA concentrations of 4 parts per billion in drinking water as a mere “shot glass … spread among 250 railroad tankers.” 

Since 2005, research has repeatedly documented the dangers of exposure to this supposedly “negligible” – and, at the time legal – level of PFOA. 

That same concentration would today be 1,000 times the Environmental Protection Agency’s legal limit for PFOA in drinking water, currently set at 4 parts per trillion.

Chemical companies and pesticide manufacturers have long argued that low doses are safe. For example, Dow, a global materials science manufacturer, lists “the dose makes the poison” on its position statement page, arguing that “as a dose increases . . . the likelihood of a toxic response increases as well.” 

Despite the wealth of peer-reviewed literature indicating otherwise, Dow maintains that findings of the toxicity of low doses are unsubstantiated.

Outcomes matter in defining safe doses

A “safe” dose is safe only for the specific health outcomes being measured. 

Traditional tests often look for obvious signs of harm, like organ damage or a specific birth defect. But they may completely miss changes in other parts of the body, like the immune or nervous systems.

This means a chemical can be labeled safe at a certain level because it doesn’t cause organ damage in animals, even if the same dose is high enough to disrupt hormones or immunity. 

What we define as the level at which a chemical becomes a poison depends entirely on which part of the body we’re looking at.

For example, PFAS were long considered safe at levels that didn’t appear to harm the liver. But once scientists researched impacts on immunotoxicity, they found these supposedly safe doses contributed to suppressed immune responses in children, prompting increased research and regulator scrutiny, including restrictions and bans on use and lower limits for allowable water contamination.  

When setting a drinking water standard, the EPA evaluated data about all available health outcomes. It found that, in the case of PFOA, low exposure levels could lead to increased cholesterol, decreased birth weight, weakened immune response and liver harm.

The herbicide dimethyl tetrachloroterephthalate, commonly known as DCPA and sold under the brand name Dacthal, was initially approved in 1958 and deemed safe for use. In 2024, the EPA banned it following new findings that linked the pesticide to “irreversible harm to unborn babies’ developing brains,” among several other hormonal issues.

It’s more complicated than just dose

The science now suggests a more refined interpretation of Paracelsus’s statement: the dose matters, but the timing, the individual, and what else one is exposed to are also critical aspects in predicting harm.

While it’s generally true that a chemical is more toxic at higher doses, there are cases where that is not the whole picture. “The dose makes the poison” is overly simplistic and has been used for years to defend the continued use of harmful chemicals. The dose contributes to the poison, but there are many other factors at play.

And that’s why legal does not always mean safe.
