Reflecting on her childhood, Tucson, Ariz., Mayor Regina Romero points to her father as the figure who lit an environmentalist fire within her.
Any chance he'd get, Romero's father would take his wife and six kids to an 800-acre ranch in the Sierra Madre mountain range of Sonora, where they learned how to ride horses, direct cattle, and to respect the wildlife, such as bobcats and brown bears.
"We invaded their space," he would tell them.
At the ranch, there was an outhouse instead of running water, rivers instead of showers. It was very rudimentary, Romero told EHN.
But riding through these biodiverse mountains on horseback made it all worth it.
"It was just so liberating," Romero said.
Five years ago, Romero's father passed away. Still his legacy lives on, as Romero, the first-ever Latina mayor of America's 33rd largest city, uses her platform to build an environmentally resilient community.

In Feb., Romero solidified a pledge to plant 1 million trees in the semi-arid desert city by 2030, when she joined the 1t.org US Chapter Stakeholder Council, a group of public, private and nonprofit leaders committed to the restoration of 1 trillion trees globally.
The U.S. chapter, including REI, National Forest Foundation, Amazon, the City of Dallas and the City of Tucson, have committed to more than 1 billion trees thus far.
Romero's goal: adapting to a rapidly changing climate in the country's third fastest warming city.
"Climate change waits for no one," Romero said. "Without a liveable community, we have no Tucson."
Romero, urban forestry manager Nicole Gillet, and local groups such as Tucson Clean and Beautiful, are prioritizing tree-planting in low-income communities, which are disproportionately burdened by Tucson's urban heat island effect.
"We have to attack the problem where the problem exists," Romero said.
According to a Climate Central report, Tucson has warmed by 4.48 degrees Fahrenheit since the first Earth Day in 1970, which is more than Phoenix, 110 miles to the north.
Recent research shows that some Tucson neighborhoods are up to 8 degrees F warmer than the city's average. Neighborhoods with the highest Latino populations are 4 to 5 degrees F warmer on average.
"It's not that the heat is seeking out low-income populations," lead author, John Dialesandro, a Ph.D. candidate studying urban climatology at University of California, Davis, told EHN. "It's a lack of greenspace."
In the desert Southwest, the extra heat that low-income neighborhoods endure often coincides with lack of air conditioning. Many households must choose between air conditioning, healthcare, and food, one University of Arizona paper said.
These communities with less indoor cooling often have fewer trees to provide shade as well.
Some Tucson neighborhoods with high poverty rates are only 1 to 2 percent shaded by tree canopy, according to an American Forests tree equity map.
This is an issue of public health, Adriana Zuniga, an assistant research scientist in the University of Arizona's College of Architecture, Planning and Landscape Architecture, told EHN.
"It affects quality of life," Zuniga said. "Vegetation is linked to better air, lower temperatures, less stress, studies show less use of antidepressant medication."
Trees help biodiversity

According to Zuniga, urban vegetation can also alleviate issues facing desert biodiversity, especially migratory species.
"Their habitats have been fragmented so much from urbanization that every spot of vegetation counts," Zuniga said.
Migratory pollinators are declining in the Sonoran Desert. More than 10,000 pollinator species are at risk in the Southwest, according to the Desert Botanical Garden in Phoenix.
The monarch butterfly, known for its remarkable blood-orange wings, is a keystone species that relies on nectar resources in southern Arizona during its spring migration.
Over the last two decades, monarch populations have fallen by 80 percent. Some of the causes include climate change, drought, deforestation and declines in milkweed plants, which female monarchs rely on for laying eggs.
"They desperately, desperately need our help in developing those patches of habitat for them to use while they migrate back and forth from Mexico, all the way to Canada," Zuniga said.
Restoring the watershed during a drought
Trees need water. And the Southwest is in a drought.
2020 was Tucson's driest year on record, at only 4.17 total inches of rainfall.
Thus, planting 1 million trees in the next decade has faced criticism.
Thats frickin right, Tucson already has water restrictions on landscaping and Romero wants to plant a million trees. W.T.F.!!!https://t.co/GWeM4zV5wH — Rancho-Del-Los-Valkayrie (@RnchoDelValkyri) February 5, 2021
But Lisa Shipek, executive director of Watershed Management Group in Tucson, believes that the initiative is realistic if native, drought-tolerant trees are planted.
"Velvet mesquite trees, desert ironwood, blue palo verde—there are a number of trees that are very appropriate to plant in the city, are found at these low elevations, and can be sustained just on rainwater," Shipek told EHN.
In fact, Shipek said, planting 1 million trees could actually restore parts of the Tucson watershed.
Before the mid-1900s, Tucson had a platter of perennially flowing rivers and creeks, such as the Santa Cruz River, Rillito River, and Sabino Creek. Then came over-pumping and massive urban development.
Now, it is rare to see flowing water.
In urban areas, where much of the surface is paved and impermeable, the million tree initiative could allow more rainfall to reach Tucson's watershed, according to Shipek.
"Putting in a rain basin with every single tree will help restore the watershed and ensure more water is infiltrated where the rain is falling," Shipek said.
A rain basin is a surface that allows rainwater to soak in and feed the trees, and indirectly, Tucson's groundwater. Groundwater contributes to streamflow.
Rainwater will be the primary fuel for the million trees initiative. When Romero entered office, she and her council approved a green stormwater infrastructure fee, which charges the average residential water-user $1 per month. Over the next three years, the fee will generate up to $7 million for sustainable stormwater harvesting in parks, streets, and parking lots, according to Romero.
Relying on rain in a drought is tricky, but according to Katie Gannon, program director at Tucson Clean and Beautiful, rain will reach these trees by way of nature. When more trees are present, the surrounding air becomes cooler, causing more clouds to drift into the low-pressure system, she told EHN.
Caught in a deadly heatwave, David Azevedo's effort to impress in a new job tragically cost him his life, underscoring the urgent need for better protections for outdoor workers.
David Azevedo, working in extreme heat on a French construction site, succumbed to heatstroke, demonstrating the severe risk posed by rising temperatures.
Despite showing signs of severe heat illness, David was left unattended for critical moments, which may have contributed to his death.
The incident reveals the urgent necessity for stronger safety regulations to protect workers in increasingly frequent and severe heatwaves.

CAMERON PARISH, La. — Late into the night, John Allaire watches the facility next to his home shoot 300-foot flares from stacks.
He lives within eyesight of southwest Louisiana’s salty shores, where, for decades, he’s witnessed nearly 200 feet of land between it and his property line disappear into the sea. Two-thirds of the land was rebuilt to aid the oil and gas industry’s LNG expansion. LNG — shorthand for liquified natural gas – is natural gas that's cooled to liquid form for easier storage or transport; it equates to 1/600th the volume of natural gas in a gaseous state. It’s used to generate electricity, or fuel stove tops and home heaters, and in industrial processes like manufacturing fertilizer.
In the U.S., at least 30 new LNG terminal facilities have been constructed or proposed since 2016, according to the
Oil and Gas Watch project. Louisiana and Texas’ Gulf Coast, where five facilities are already operating, will host roughly two-thirds of the new LNG terminals – meaning at least 22 Gulf Coast LNG facilities are currently under construction, were recently approved to break ground or are under further regulatory review.
Although the U.S. didn’t ship LNG until 2016, when a freight tanker left, a few miles from where Cameron Parish’s LNG plants are today, last year the country became the global leader in LNG production and export volume, leapfrogging exporters like Qatar and Australia. The
EIA’s most recent annual outlook estimated that between the current year and 2050, U.S. LNG exports will increase by 152%.
Allaire, 68, watches how saltwater collects where rainwater once fed the area’s diminishing coastal wetlands. “We still come down here with the kids and set out the fishing rods. It's not as nice as it used to be,” he told
Environmental Health News (EHN).
That intimacy with nature drew Allaire to the area when he purchased 311 acres in 1998. An environmental engineer and 30-year oil and gas industry veteran, he helped lead environmental assessments and manage clean-ups, and although retired, he still works part-time as an environmental consultant with major petroleum companies. With a lifetime of oil and gas industry expertise, he’s watched the industry's footprint spread across Louisiana and the Gulf of Mexico’s fragile shores and beyond. Now that the footprints are at the edge of his backyard, Allaire is among a cohort of organizers, residents and fisher-folk in the region mobilizing to stop LNG facility construction. For him, the industry’s expansion usurps the right-or-wrong ethics he carried across his consulting career. For anglers, oil and gas infrastructure has destroyed fishing grounds and prevented smaller vessels from accessing the seafood-rich waters of the Calcasieu River.
From the view of Allaire’s white pickup truck as he drives across his property to the ocean’s shore, he points to where a new LNG facility will replace marshlands. Commonwealth LNG intends to clear the land of trees and then backfill the remaining low-lying field.
“You see what’s happening with the environment,” Allaire said. “When the facts change, I got to change my mind about what we’re doing.”

During an Earth Day rally in April, community members gathered in the urban center of Lake Charles to demand local oil and gas industries help deliver a safer, healthier future for all. In between live acts by artists performing south Louisiana’s quintessential zydeco musical style, speakers like James Hiatt, a Calcasieu Parish native with ties to Cameron Parish and a Healthy Gulf organizer, and RISE St. James organizer Sharon Lavigne, who’s fighting against LNG development in rural Plaquemines Parish near the city of New Orleans, asked the nearly 100 in attendance to imagine a day in which the skyline isn’t dotted by oil and gas infrastructure.
Not long ago, it was hard to imagine an Earth Day rally in southwest Louisiana at all. For decades, the area has been decorated with fossil fuel infrastructure. Sunsets on some days are highlighted by the chemicals in the air; at night, thousands of facilities’ lights dot the dark sky.
“It takes a lot of balls for people to start speaking up,” Shreyas Vasudevan, a campaign researcher with the Louisiana Bucket Brigade, told EHN in the days after the rally. In a region with its history and economy intertwined with oil and gas production, “you can get a lot of social criticism – or ostracization, as well – even threats to your life.”
Many are involved in local, regional and national advocacy groups, including the Louisiana Bucket Brigade, Healthy Gulf, the Sierra Club, the Natural Resources Defense Council, the Turtle Island Restoration Network, the Center for Biological Diversity and the National Audubon Society.

But environmental organizers are fighting a multi-billion-dollar industry with federal and state winds at its back. And LNG’s federal support is coupled with existing state initiatives.
Under outgoing Louisiana Gov. John Bel Edwards — a term-limited Democrat — the state pledged a goal of reaching net-zero greenhouse emissions by 2050. Natural gas, which the LNG industry markets as a cleaner-burning alternative, is cited as one of the state’s solutions. Louisiana is the only state that produces a majority of its carbon emissions through fossil fuels refining industries, like LNG, rather than energy production or transportation. Governor Edwards’ office did not return EHN’s request for comment.
This accommodating attitude towards oil and gas industries has resulted in a workforce that’s trained to work in LNG refining facilities across much of the rural Gulf region, said Steven Miles, a lawyer at Baker Botts LLP and a fellow at the Baker Institute’s Center on Energy Studies. Simultaneously, anti-industrialization pushback is lacking. It’s good news for industries like LNG.
“The bad news,” Miles added. “[LNG facilities] are all being jammed in the same areas.”
One rallying cry for opponents is local health. The Environmental Integrity Project found that LNG export terminals emit chemicals like carbon monoxide –potentially deadly– and sulfur dioxide, of which the American Lung Association says long-term exposure can lead to heart disease, cancer, and damage to internal or female reproductive organs.
An analysis of emissions monitoring reports by the advocacy group the Louisiana Bucket Brigade found that Venture Global’s existing Calcasieu Pass facility had more than 2,000 permit violations.That includes exceeding the permit’s authorized air emissions limit to release nitrogen oxides, carbon monoxide, particulate matter and volatile organic compounds 286 out of its first 343 days of operation.
The Marvel Crane, the first liquid natural gas carrier to transport natural gas from the Southwest Louisiana LNG facility, transits a channel in Hackberry, Louisiana, May 28, 2019.
“This is just one facility,” at a time when three more facilities have been proposed in the region and state, Vasudevan said. Venture Global’s operational LNG facility — also known as Calcasieu Pass — “is much smaller than the other facility they’ve proposed.”
In an area that experienced 18 feet of storm surge during Hurricane Laura in 2020 — and just weeks later, struck by Hurricane Delta — Venture Global is planning to build a second export terminal Known as “CP2,” it’s the largest of the roughly two dozen proposed Gulf LNG export terminals, and a key focal point for the region’s local organizing effort.
Residents “don’t really want LNG as much as they want Cameron [Parish] from 1990 back,” Hiatt told EHN of locals’ nostalgia for a community before storms like Rita in 2005 brought up to 15 feet of storm surge, only for Laura to repeat the damage in 2020. Throughout that time, the parish’s population dipped from roughly 10,000 to 5,000. “But the wolf knocking at the door is LNG. Folks in Cameron think that's going to bring back community, bring back the schools, bring back this time before we had all these storms — when Cameron was pretty prosperous.”
“Clearly,” for the oil and gas industry, “the idea is to transform what was once the center of commercial fishing in Louisiana to gas exports,” Cindy Robertson, an environmental activist in southwest Louisiana, told EHN.
Helping fishers’ impacted by LNG is about “actual survival of this unique culture,” Cooke said.
In a measure of organizers’ success, she pointed to a recent permit hearing for Venture Global’s CP2 proposal. Regionally, it’s the only project that’s received an environmental permit, but not its export permit, which remains under federal review. At the meeting, some spoke on the company’s behalf. As an organizer, it was a moment of clarity, Cooke explained. Venture Global officials “had obviously done a lot of coaching and organizing and getting people together in Cameron to speak out on their behalf,” Cooke said. “So, in a way, that was bad. But in another way, it shows that we really had an impact.”
“It also shows that we have a lot to do,” Cooke added.
Environmental organizers like Alyssa Portaro describe a sense of fortitude among activists — she and her husband to the region’s nearby town of Vinton near the Texas-Louisiana border. Since the families’ relocation to their farm, Portaro has worked with Cameron Parish fisher-folk.
“I’ve not witnessed ‘community’ anywhere like there is in Louisiana,” Portaro told EHN. But a New Jersey native, she understands the toll environmental pollution has on low-income communities. “This environment, it’s so at risk — and it’s currently getting sacrificed to big industries.”
“People don’t know what we’d do without oil and gas. It comes at a big price,” she added.
Southwest Louisiana’s Cameron Parish is one of the state’s most rural localities. Marine economies were the area’s economic drivers until natural disasters and LNG facilities began pushing locals out, commercial fishers claim.

A disappearing parish
The stakes are seemingly higher for a region like southwest Louisiana, which is the epicenter of climate change impacts.
In nearly a century, the state has lost roughly 2,000 square miles of land to coastal erosion. In part driving the state’s erosion crisis is the compounding impacts of Mississippi River infrastructure and oil and gas industry activity, such as dredging canals for shipping purposes, according to a March study published in the journal Nature Sustainability. Louisiana’s Coastal Protection and Restoration Authority said Cameron Parish could lose more land than other coastal parishes over the next 50 years. A recent Climate Central report says the parish will be underwater within that time frame.
On top of erosion and sea level rise impacts, in August, 2023, marshland across southwest Louisiana’s Cameron Parish burned. The fires were among at least 600 across the Bayou State this year. Statewide, roughly 60,000 acres burned — a more than six-fold increase of the state’s average acres burned per year in the past decade alone.
But while the blaze avoided coastal Louisiana communities like Cameron Parish, the fires represented a warning coming from a growing chorus of locals across the region — one that’s echoes by the local commercial fishing population, who claimed to have experienced unusually low yields during the same time, according to a statement from a local environmental group. At the site of the Cameron Parish fires are locations for two proposed LNG expansion projects.
"The idea is to transform what was once the center of commercial fishing in Louisiana to gas exports.” - Cindy Robertson, an environmental activist in southwest Louisiana
It was an unusual occurrence for an area that’s more often itself underwater this time of year due to a storm surge from powerful storms. For LNG expansion’s local opposition, it was a red flag.
As the Louisiana Bucket Brigade has noted prior, the confluence of climate change’s raising of sea levels and the construction of LNG export terminals — some are proposed at the size of nearly 700 football fields — are wiping away the marshland folks like Allaire watched wither. Among their fears is that the future facilities won’t be able to withstand the power of another storm like Laura and its storm surge, which wiped away entire communities in 2020.
Amidst these regional climate impacts, LNG infrastructure has shown potential to exacerbate the accumulation of greenhouse gasses that cause global warming. For the most part, LNG is made up of methane — a greenhouse gas that’s more than 80 times more potent than carbon dioxide in the atmosphere. Among the 22 current LNG facility proposals, the advocacy group Sierra Club described a combined climate pollution output that would roughly equal to that of about 440 coal plants.
The climate impacts prompt some of the LNG industry’s uncertainty going forward. It isn’t clear if Asian countries, key importers of U.S. LNG, will “embrace these energy transition issues,” said David Dismuke, an energy consultant and the former executive director of Louisiana State University’s Center for Energy Studies. Likewise, European nations remain skeptical of embracing LNG as a future staple fuel source.
“They really don't want to have to pull the trigger,” Dismukes added, referring to Europe’s hesitation to commit more resources to exporting LNG from the American market. “They don't want to go down that road.”
While there will be a tapering down of natural gas supply, Miles explained, “we’re going to need natural gas for a long time,” as larger battery storage for renewables is still unavailable.
“I'm not one of these futurists that can tell you where we're going to be, but I just don't see everything being extreme,” Dismukes said. “I don't see what we've already built getting stranded and going away, either.”
For now, LNG seems here to stay. From 2012 to 2022,U.S. natural gas demand — the sum of both domestic consumption and gross exports — rose by a whopping 43%, reported the U.S. Energy Information Administration, or EIA. Meanwhile, in oil and gas hotbeds like Louisiana and Texas, natural gas demand grew by 116%.
Throughout 25 years, Allaire has witnessed southwest Louisiana’s land slowly fade, in part driven by the same industrial spread regionally. Near where the front door of his travel trailer sits underneath the aluminum awning, he points to a chenier ridge located near the end of the property. It’s disappearing, he said.
“See the sand washing over, in here?” Allaire says, as he points towards the stretches of his property. “This pond used to go down for a half mile. This is all that's left of it on this side.”
As climate change intensifies, scientists are exploring geo-engineering as a potential solution, but the approach raises both hope and serious concerns.
Geo-engineering aims to cool the planet by manipulating the climate, but experts warn it could disrupt weather patterns and divert attention from reducing carbon emissions.
Techniques like marine cloud brightening and stratospheric aerosol injection show promise but also pose risks, such as exacerbating droughts and altering global weather.
Conspiracy theories around geo-engineering are on the rise, complicating scientific research and public acceptance.

Vice President Harris, known for her strong environmental stance, might carry forward Biden’s climate policies with significant implications for the U.S.'s climate future.
Environmentalists have praised Harris' voting record on environmental issues, including sponsoring the Green New Deal.
The Biden-Harris administration has significantly advanced renewable energy through the Inflation Reduction Act and reversed Trump-era rollbacks on pollution regulations.
Harris’s running mate selection could influence her climate agenda, especially in battleground states reliant on fossil fuels.

Donald Trump and Joe Biden are both promoting U.S. fossil fuel exports, but Europe's decreasing gas demand could undermine these plans.
Europe's commitment to reducing emissions has led to a significant drop in gas usage, with a shift towards renewable energy.
U.S. companies, expecting a decline in European demand, are pivoting towards Asia for future gas and LNG markets.
Key quote:
"We expect that demand for natural gas is going to continue declining at pace. Given we have these climate commitments, the expectation is that demand will be lower by 2030, even lower by 2040, with the effect that there is no long-term gas demand in Europe."
— Georg Zachmann, senior fellow at economics think tank Bruegel
Why this matters:
The clash between U.S. fossil fuel ambitions and Europe's renewable energy goals could lead to oversupply and economic repercussions. As Europe reduces gas dependency, American companies will need to adapt to changing global energy demands.
The Inflation Reduction Act and other federal programs provide significant funding for lithium mining to meet the demand for electric vehicle batteries.
Lithium mining methods, such as brine evaporation and hard rock mining, pose substantial risks to groundwater supplies and biodiversity.
Local communities and environmentalists are opposing new mining projects, fearing long-term ecological damage and threats to sacred Indigenous sites.
Key quote:
"We need lithium as a part of our transition off of fossil fuels, but it can’t come at the expense of biodiversity or our most precious protected areas."
— Patrick Donnelly, Center for Biological Diversity
Why this matters:
Increased lithium mining is critical for the energy transition, but it threatens water resources and ecosystems, especially in arid regions. Effective regulations and alternative battery technologies are needed to balance environmental concerns with energy needs.
Power shutoffs or wildfire evacuations can be deadly for disabled people, especially nondrivers who may not have a way to get to a cooling center or evacuation point.
