Nepal’s rhino conservation efforts have been, if anything, too successful.

Ganesh Paudel packs a wad of chewing tobacco as he talks about the rhinoceros attack. “When the rhino charged, we were in a boat,” he tells me. “The rhino was sitting in the water, then it hit me and broke my knee, broke the hand of another guide and gored a tourist” — he points — “through an eye.”
As we chat, another rhino wades in a stream just a short way away. Paudel works as a nature guide, but we’re not in nature today — we’re standing under a bridge that connects to a busy highway in Chitwan, a district of about a million people situated on the outskirts of Nepal’s Chitwan National Park. A school bus passes and a few locals stop their scooters to whip out phones and film. But most keep moving without looking twice.
Rhinos once roamed from Pakistan to Bangladesh, but their numbers plummeted in the 20th century. Many cultures throughout Asia believe rhino horns have medicinal properties, making the creatures they’re attached to vulnerable to poaching. Rajas and royals prized rhinos as trophy kills. Farmers, also, retaliated with violence against rhinos that pillaged their crops. By 1970 there were just 95 rhinos in the national park, a wilderness bigger than New York City.
Eventually, however, the government realized that wildlife protection attracts dollars. For decades now, the United States Agency for International Development and non-governmental organizations like the World Wildlife Fund have supported Nepal’s efforts to boost conservation and lessen human wildlife conflict. Between 2011 and 2020 alone, $57 million of USAID funding went to programs aimed at protecting biodiversity here. Soldiers now patrol the park to stifle poaching.
But while the rhino population has rebounded to nearly 700 in Chitwan, the animals themselves are hardly thriving. As temperatures rise, there's been less rain during monsoon season. Warming temperatures have fueled invasive species like American creeper vines that have taken over rhino habitat and grow three inches daily. Climate change has also dried up staple rhino foods like elephant grass and aquatic plants. Now, there are too many rhinos and not enough forest, which forces the animals out of the park and into the city. (The same goes for tigers.)
The particular rhino wading near us is named Meghauli. Each morning, like clockwork, he comes out of the forest and into town. Meghauli is a bona fide social media star. When he thuds down the road traffic stops and a parade of hypnotized Nepalis and foreigners snap selfies and touch his leathery hide.
Meghauli was hand-raised by park staff after he was found alone, wounded from a tiger attack. Fed on 18 liters of buffalo milk a day, he grew big and strong — and also lost his fear of humans. Four years later he was released, but he kept returning because it’s easier to find food in town than in the increasingly dry and crowded jungle.
Rhinos are everywhere in the populated regions around the park — wading in streams, but also painted in murals, memorialized in hotel names, and depicted in statues. The uncomfortable truth is that the rhinos’ plight has also created a lucrative tourist opportunity. Rajendra Dhami, who runs a tea shop in front of Meghauli’s main crossing point, a shallow river with basking crocodiles and waiting tourists, tells me the rhinos have become a big attraction. “People come to see rhinos since we have them,” he says. “That means more money for us.”
A pair of young Brits and an Indian family of nine are currently gathered, waiting for Meghauli, but Dhami insists that for the most part, it doesn’t matter which rhino shows up. “We have lots of problems in Nepal,” he tells me, “but we share with wildlife.”
It’s true visitors often choose hotels and shops near wildlife. But a recent 20-year study found that nature-based tourism rarely impacts locals, in part because hotel bookings are often made online with fancy tour operators who act as middlemen and skim off revenue much the same way food delivery sites take from restaurants. Meanwhile, just six of the 93 hotels here are owned or managed by indigenous people, according to the Regional Hotel Association Chitwan. For most Nepalis, especially in poor indigenous communities who rely on farming here, rhinos running around is bad for bottom lines — and bellies.
“Cabbage, cauliflower, potatoes, rhinos like it all very much” says Narayan Rijal, who has worked as a park guide for 15 years. ”That’s the problem.”
But people, also, are hungry. Many here are in such need of food that they’re invading rhino habitat to find fruits, honey, and meat. Impoverished communities illegally enter the park to gather firewood, a cycle that increases deforestation, shrinks habitat, and risks deadly rhino, elephant, and tiger attacks.
Tulsi Magar, a guide at the local Sanctuary hotel, says many attacks are because farmers are so desperate to protect their own food that they stand their ground and light fires to try and scare off hungry rhinos. When Magar was 12, he also fought this way, sleeping in a shed and narrowly avoiding losing his life to protect the family’s radish harvest.
“It didn’t work,’ he remembers. “The rhinos won.”
Soldiers try their best to manage the rhinos, trailing them as they leave the park to forage in farmers’ fields. Once they reach town, soldiers often have to hit them with sticks or their rifle butts to get them to return to the forest.
“They‘re not small animals,” an assistant warden says as a rooster crows outside his office. “We try to push rhinos back into the core area. With Meghauli no need for stick, we just push. We do our best.”
Meghauli has a lookalike named Madi, another rescue. Unlike Meghauli, Madi is angry, park staff say, asking me to avoid using their names for fear of speaking openly. “Madi even charged a few taxis by the airport,” they admit. “He’s very aggressive.”
Rhinos have killed 55 people since 1998, including a 2019 attack on safari-going tourists. Last year alone, rhinos killed five. “They’re more dangerous than tigers,” notes Isswari Chapagain who has climbed trees to avoid charges.
Rhinos aren’t just a threat to locals, he says. They’re also a threat to each other. Wild rhinos go nuts and attack orphans like Meghauli and Madi if they smell people on them — another reason they keep coming back to town.
As the park has become famous and rhinos have rebounded, human activities like road expansion have been linked to a string of strange deaths: 165 rhinos killed from falling into roadside ditches and septic tanks, shocks from electric fences, disease (likely from proximity to livestock), and at least six killed by poachers. In 2022 alone, 36 rhinos died from territorial fights, which are also connected to warming temperatures and habitat loss. Construction on Chitwan’s three main rivers changes their flow, shrinks space, increases food competition and pushes rhinos into fields.
Rhinos are protected even if they attack or leave the park boundaries, but people aren’t. If they’re attacked in the park, Nepalis can claim government compensation (although guides cannot). If they’re at home protecting their farms and a rhino mauls them, they get nothing, another reason researchers accuse the government of continuing to prioritize wildlife over people.
Back under the bridge, I watch Meghauli blow bubbles under the water, just like a kid.
When he rises, I see his massive body in full for the first time. He seems gentle but it wouldn’t take much — a jerk of his head or a kick from a leg — for him to kill someone. He exits the water and trudges up the riverbank, then pauses to scan the highway. He faces me and sniffs the air, then turns toward a potato field. It’s lunchtime.

What are the health risks? How can I protect myself? And will my plants be okay?
If you live anywhere near the Great Lakes or Mid-Atlantic (or certain parts of the Mountain West), odds are it’s smoky where you live. Wildfires raging in western Ontario are sending smoke cascading south and east across the U.S., prompting widespread air quality alerts affecting millions of Americans.
The good and — very bad — news is that we’ve been here before. Here’s a look back at some of Heatmap’s coverage from the summer of 2023, when smoke produced by forest fires in Quebec blanketed 128 million people in a murky haze and turned the New York City skyline an ominous shade of orange.
One day — even just one hour — of smoke inhalation can exacerbate pre-existing health conditions and increase an individual’s chance of premature death by 12%. To stay safe, Jeva Lange recommends avoiding prolonged outdoor exposure and masking up when you go outside.
Wildfire smoke is full of tiny pollutants that can leak into your apartment even when the windows and doors are sealed tight. That’s where air purifiers come in, Matthew Zeitlin writes.
Tinted skies are now a rare, remarkable event. But decades ago, before targeted policy interventions, this was everyday life for New Yorkers. Here’s Jeva with more on the legacy of the Clean Air Act.
Before you step out for a run, read Emily Pontecorvo’s guide to what the Air Quality Index is and isn’t telling you.
People should not inhale smoke because of its dangerous health effects. But plants, interestingly, may actually thrive. Allow Jeva to explain.
Current conditions: Wildfire smoke tinted the skies orange across the Northeastern United States, rendering the air on New York’s Long Island thick and hazy all afternoon • London is a balmy 83 degrees Fahrenheit today, but new research shows that the number of days topping 86 degrees has quadrupled since the 1980s • Chile declared a state of emergency across 10 regions ahead of a series of major storms.
The resumption of fighting between the United States and Iran over the Strait of Hormuz could hammer energy markets harder than the previous phase of the conflict, as the crude stockpiles governments tapped at a record volumes to avert the worst economic impact of the war are now depleted. That’s the warning oil traders issued to the Financial Times on Wednesday. “We’ve burned through all of the buffers we had. Everything,” one trader said. “All of that’s now gone.” The gloomy assessment came as The Wall Street Journal reported that President Donald Trump has weighed expanding the U.S. military operation in Iran.
The U.S. Energy Information Administration, meanwhile, released its short-term energy outlook for July, in which the agency estimated that global crude oil inventories declined by 5.1 million barrels per day throughout the second quarter of this year, marking a decline above the seasonal average for that period over the past five years. Even before the conflict picked up again, my colleague Matthew Zeitlin wrote that it would be a long time before the Strait of Hormuz returned to normal operations. Don’t hold your breath.

In the steamy final weeks of August 2019, I found myself on Puerto Rico’s southeast shores. Set against the backdrop of the island’s central mountain range with streams that quench its underground aquifers, this sun-soaked coastal plain was coveted by Spanish and American sugar barons for centuries before transforming into a hub for U.S. agribusiness in recent decades. By the time I arrived, the aquifer was facing threats on multiple fronts. The Puerto Rico Aqueduct and Sewer Authority — known as PRASA or AAA in its Spanish acronym — was losing, by some estimates, more than half the water in its system to leakage, forcing the state-owned utility to draw more from aquifers. With the island’s electrical system still in tatters from Hurricane Maria and its debt at crushing levels, PRASA had little capacity to make the upgrades needed to prevent further decline. Meanwhile, local environmentalists accused regulators of providing little to no oversight of how much water industrial facilities drew from their wells. The story I ultimately reported suggested that water would follow electricity as the next major infrastructure crisis. It was just being felt first, at that time, in places like the town of Salinas, where people like Manases Vega — then a 65-year-old with a chronic respiratory illness — lost access to water every two weeks due to rationing.
Now the crisis has indeed spread. Last month, I told you when Governor Jenniffer González Colón called in the National Guard to help after a major water pipeline cracked. More than a month later, El Nuevo Día reported that the ongoing shortages are forcing residents to pay up to $700 per week for water. Businesses are paying up to $3,500 per week to buy enough bottles to cook, clean, and flush toilets. Hotels are spending up to $100,000, the island’s newspaper of record also reported last week. “We were without water for more than 50 days here on Calle Loíza,” Jonathan Collazo, a restaurant owner, said, referring to the popular street with bars and restaurants in Santurce, roughly the equivalent of San Juan’s Williamsburg.
For 12 years, Péter Szijjártó served as Hungary’s top diplomat in the government of former Prime Minister Viktor Orbán. On Wednesday, he announced his resignation from parliament to take a job at China’s top electric automaker. “I have received an extremely honorable offer to fill an international position from one of the world’s leading companies,” he wrote in a post on Facebook. “BYD is one of the greatest automotive success stories of the past twenty years and is also the world’s leading manufacturer of new energy vehicles.” His critics may quibble with the word “honorable.” Szijjártó established his relationship with the company while serving as foreign minister, and his government had planned to provide subsidies to BYD to open its new hub in Budapest. Just a few months ago, CNBC reported that the European Union was investigating labor violations at BYD’s factory in Szeged. Last month, the Hungarian investigative site 444 reported that a worker died at the plant.

The Department of Energy has granted the startup SuperCritical Materials an exclusive license to commercialize patented technology to extract uranium from seawater. The deal requires the Austin-based company to manufacture and deploy the technology in the U.S. before exporting to allied nations, according to The Northern Miner. The concept of drawing uranium out of seawater has existed for years, an idea that took root before the vast new reserves of the metal were discovered on land. But seawater extraction remained on the agenda in countries without access to mines. When I visited the Philippines in 2024 to report on the country’s nuclear ambitions, I met scientists at the state atomic energy agency who were researching methods to secure a uranium supply from the water. But Ted Garrish, the assistant U.S. secretary of nuclear energy, said “this technology represents a potentially significant contribution to America’s long-term fuel security and industrial competitiveness.”
On Tuesday, New York Governor Kathy Hochul signed an executive order enacting the nation’s first statewide moratorium on data centers. On Wednesday, Michigan Governor Gretchen Whitmer, a fellow Democrat, staked out a different position, unveiling what E&E News called a “package of 10 commitments to ensure companies pay the full cost of construction, operation, power, and water” from new data centers for artificial intelligence. “On my watch, Michiganders have been protected from any rate increases due to data center development and we adopted some of the strongest protections for people and communities, but we need to do more,” Whitmer said in a statement.
“It’s been exciting to see different states — and, to be blunt, to see Democratic-governed states, particularly those in the Northeast and Mid-Atlantic — try to take on the data center boom. It’s good to see them test out ideas, solve problems through legislation, and harness this moment for the public good without strangling the buildout entirely,” my colleague Robinson Meyer wrote yesterday. “For too long, blue states have leaned into a particular economic model, one in which states want to attract varying forms of development but in fact succeed only in creating new suburbs, office buildings, and warehouses.”
It is, according to Bloomberg, “the plastic America loves to hate.” But a new industry group wants to save polystyrene by convincing lawmakers to stop targeting styrofoam. Formed by 17 companies that produce the material, the Polystyrene Recycling Alliance aims to forestall bans by making sure styrofoam is treated as recyclable under state packaging laws. “There’s the narrative that polystyrene is not part of the circular future,” Justin Riney, chair of the alliance and an executive at manufacturer Ineos Styrolutions, told the newswire. “We are adamant that we have the data, and we know that our products are part of the future.”
Proposed reforms to Europe’s Emissions Trading System could see the EU itself become a carbon credit customer.
The European Union is on the verge of making major changes to its carbon market, including integrating carbon removals into the scheme for the first time.
The bloc’s highest governing body, the European Commission, is expected to publish a proposal on Friday to reform the EU Emissions Trading System, or ETS, to align it with the EU’s 2040 emissions target. Under the current rules, companies cannot use carbon credits of any kind to comply with the regulations. But as 2040 grows closer, the EU plans to rely on carbon removal to offset some of the residual emissions from industries that are the most difficult to decarbonize.
Friday’s proposal will cover which types of carbon removal will be accepted, how many carbon removal credits can enter the market and when, and who will be allowed to buy them. One leading approach would have the EU government buy carbon removal directly, which would give the industry unprecedented market certainty.
“The ETS could be the single biggest driver of demand for carbon removal for the next decade,” Felix Grey, a policy manager for the carbon registry Isometric, told me.
The ETS enforces a cap on emissions that declines over time. Large emitters located in the EU must buy “allowances” for each ton of carbon they release, while the pool of available allowances shrinks apace with the emissions cap. Last year, the EU set a new target to reduce emissions 90% below 1990 levels by 2040, building off its earlier target of a 55% reduction by 2030. The upcoming proposal will address how the market should operate between 2030 and 2040 to achieve that goal.
There are many contentious questions surrounding this next phase, including how quickly the cap should decline over the decade. Another question is how many free allowances the EU should give to energy-intensive facilities such as steelmakers and fertilizer producers, which it does to prevent them from leaving Europe due to higher operating costs. Now that the EU has launched its carbon border adjustment mechanism, which taxes higher-carbon imports of these goods, free allowances may not be as necessary.
The integration of carbon removal is also controversial. At best, it could be an opportunity to improve and scale up nascent technologies that take carbon out of the atmosphere. At worst, it could enable polluters to avoid cutting their own emissions by purchasing carbon credits that don’t represent real climate benefits. Then there’s the possibility that removals will be so expensive that their integration into the ETS will have no effect at all — that is, it will be less expensive for companies to pursue emissions reductions than to buy their way out. The outcome will depend on the rules the EU Commission proposes and what its member states ultimately agree to.
Today, most carbon removal efforts are supported by research grants and voluntary carbon credit purchases from companies like Microsoft. A common mantra in the industry is that it will never reach a meaningful scale without government backing. Carbon removal startups aren’t selling a product with inherent value, they are selling a waste management solution. Unless governments require polluters to clean up their carbon waste, or else handle the job themselves as a public good, carbon removal will never take off.
Some governments have already dabbled in state-sponsored removals. Under the Biden administration, the U.S. launched a carbon removal purchase pilot prize, dedicating $35 million to buy carbon removal from a handful of promising companies. It never got past the initial award phase, however, and the Trump administration has not continued the program. A number of cities and counties across the U.S. have set up their own, much smaller purchasing programs in an effort to support the industry. Making carbon removal part of a regulatory program like the EU’s ETS could open the industry to a much bigger market.
As of today, there are a few knowns and a few unknowns about what the Commission plans to propose. For example, it’s relatively clear what methods of carbon removal the European Commission will allow into the market. Earlier this year, the EU finalized regulations for certifying three kinds of carbon removal under its official Carbon Removal and Carbon Farming scheme — direct air capture, biomass with carbon capture, and biochar projects — laying out criteria for quality as well as monitoring and reporting rules. For now, only these three project types can be considered.
Here’s the problem: Direct air capture and biomass with carbon capture are two of the most expensive project types. The average carbon removal credit from these methods costs hundreds of dollars. The average price of an allowance in the ETS, by contrast, has hovered between $70 and $90 over the past few years. Depending on how the Commission chooses to incorporate the credits into the market, it’s possible that no one will buy them.
The European Commission has said it is considering three options. The leading proposal is for the EU to create a central purchasing authority that buys removals using revenues from the ETS. For each removal credit the government acquires, it would issue an additional allowance into the market on top of the established cap. This would enable regulated facilities to emit a bit more than they could otherwise — a tradeoff that Grey argued would help them stay competitive. At the same time, it would also ensure that there’s demand for carbon removal regardless of the price.
The second option is to leave it to the market, giving emitters the option to purchase carbon removal credits as an alternative to purchasing allowances. In this version, similar to the first, the carbon removal credits would enter the market as an addition to the established amount of allowances. Whether or not anyone actually buys carbon removal will depend on how tight the allowance market is.
In the third option, emitters would be able to use carbon removal credits in lieu of allowances, but those credits would operate “below the cap,” so to speak. For every credit counted toward the ETS, regulators would reduce the number of allowances available to purchase by the same amount. It is hard to see why any company would purchase carbon removal in this version unless and until the price of a credit drops below the price of an allowance, however.
Carbon Market Watch, a nonprofit watchdog group, isn’t excited about any of these options. In a recent white paper on ETS reforms, it argued that Europe should support carbon removal separate from the ETS. “Direct integration of CDR in the ETS is either a dead end, or the start of a slippery slope,” the group warned. Carbon Market Watch also has concerns about the integrity of the EU’s carbon removal certification scheme. The group has formally challenged the methodologies for certifying biochar and biomass with carbon capture projects, arguing that they do not account for all the emissions associated with these processes, lack sustainable biomass sourcing safeguards, and in the case of biochar, are missing monitoring requirements. If ETS credits are built on faulty science, the EU could end up spending billions of dollars to little climate benefit.
The other big question about the integration is the amount of carbon removal the EU will allow into the market. Even if the bloc decides to create a central purchasing authority, its potential to help the industry scale will depend on how much it commits to buying. Grey, of Isometric, argued that staying on course for net zero by 2050 would require the EU to remove about 100 million metric tons of carbon per year by 2040.
“A strong proposal on Friday will confirm carbon removal’s integration from 2031, commit to buying removal at the scale required to meet net zero, and treat every credible method equally rather than picking winners,” he said.
