Editor’s note: “A study published in 2024 found that a change in insecticide use was a major factor in driving butterfly declines in the Midwest over 17 years. The authors, many of whom were also part of the current study, noted that the drop coincided with a shift to using seeds with prophylactic insecticides, rather than only spraying crops after an infestation.”
“Only the Pacific Northwest didn’t lose butterfly population on average. This trend was largely driven by an irruptive species, meaning one with extremely high abundance in some years – the California tortoiseshell. When this species was excluded from the analyses, trends in the Pacific Northwest were similar to other regions.”
“Imagine a world without the delicate flutter of butterfly wings or the vibrant splashes of color they bring to our gardens. Sadly, this could become a reality sooner than we think. A recent study published in the journal Science has revealed a shocking decline in butterfly populations across most regions of the United States.”
A study in the United States found a dramatic 22% decline in butterfly populations between 2000 and 2020.
Previous research has focused on a specific butterfly species or regions of the country. For this study, researchers wanted to understand overall butterfly population trends across the U.S.
They gathered records of 12.6 million individual butterflies across 554 species, from more than 76,000 surveys, many conducted by citizen science groups in nearly 2,500 locations.
The researchers found that total butterfly numbers were down by 22% over the first two decades of this century. It’s a concerning trend, said Collin Edwards, lead author of the study and an ecological modeler with the state of Washington Fish and Wildlife Department.
To put it in context, “for someone who was born in 2000, one out of every five butterflies had disappeared by the time they became an adult,” Edwards told Mongabay by phone.
The 22% decline is an average. Of the 554 species examined, 107 declined by at least 50% and 22 species declined by more than 90%.
At the same time, nine species saw population increases. The eastern population of the monarch (Danaus plexippus) doubled in 2025, though its overall population is still down roughly 80%, prompting the iconic butterfly to be proposed for the U.S. endangered species list.
Several of the nine species that increased in population are predominantly found in Mexico; the U.S. is the northern edge of their range. Edwards said with a warming climate, many butterfly species are shifting their habitats north.
“If the southern edge of their limit is just barely cold enough for them, as the climate warms, that’ll get worse. But the northern edge where it used to be a little bit too cold will start to get warm enough,” Edwards said.
This study adds to a growing body of research showing a global decline in insect populations, raising concerns about a depleting food source for many animals including birds and frogs, which are facing population crashes in their own right.
Furthermore, while bees get most of the glory, butterflies are also critical pollinators. A 2021 study in Texas found butterflies provide about $120 million per year in pollination services for cotton.
Tierra Curry, a senior scientist with the Center for Biological Diversity, told Mongabay by email that “this is a landmark study” that “shows that we need to take urgent action to safeguard butterflies. Every action we take to help pollinators also helps us because our fate is directly tied to their health.” Curry wasn’t involved with this research.
Edwards said this study focused on butterflies because that’s the order of insects they had data for, but he added there’s “every reason to think that if butterflies are declining there are probably similar declines in other groups of insects,” especially since the drivers of decline — habitat loss, climate change and pesticides — affect most insects.

One of the easiest ways to check if there is MMA in your acrylic or nail supplies is to check the ingredient list of your products. It should not be listed as an ingredient in any reputable acrylic nail product. A few additional tips include: Smelling a very harsh odor when applying and filing your acrylic nails – some people say it smells like cat urine.

Environmental activists claim victory as Mitsubishi scraps $1.3 billion chemical plant in ‘Cancer Alley’
by Tristan Baurick, Verite News New Orleans
Environmental groups are claiming victory after Mitsubishi Chemical Group dropped plans for a $1.3 billion plant in the heart of Louisiana’s industrial corridor.
In the works for more than a decade, the chemical manufacturing complex would have been the largest of its kind in the world, stretching across 77 acres in Geismar, a small Ascension Parish community about 60 miles west of New Orleans. Tokyo-based Mitsubishi cited only economic factors when announcing the cancellation last week, but a recent report on the plant’s feasibility noted that growing community concern about air pollution could also hamper the project’s success.
“The frontline communities are fighting back, causing delays, and that amounts to money being lost,” said Gail LeBoeuf with Inclusive Louisiana, an environmental group focused on the industrial corridor along the Mississippi River known as Cancer Alley.
The nonprofit group Beyond Petrochemical declared the project’s failure a “major victory for the health and safety of Louisianans.”
According to Mitsubishi, the plant could have produced up to 350,000 tons per year of methyl methacrylate, or MMA, a colorless liquid used in the manufacture of plastics and a host of consumer products, including TVs, paint and nail polish.
The plant was expected to be a major polluter, releasing hundreds of tons per year of carbon monoxide, nitrogen oxides, volatile organic compounds and other harmful chemicals, according to its permit information.
Mitsubishi cited rising costs and waning demand for MMA as the reasons for dropping the project. In a statement, the company indicated the plant likely wouldn’t have enough MMA customers to cover “increases in capital investment stemming from inflation and other factors.”
In July, a report on the plant’s viability warned that a global oversupply of MMA and fierce local opposition made the project a “bad bet.”
Conducted by the Institute for Energy Economics and Financial Analysis, the report said that credit agencies are paying more attention to “community sentiment” about petrochemical projects, particularly in Louisiana. In Geismar and other parts of Cancer Alley, there’s a “disproportionately heavy concentration of polluting industrial facilities” and Mitsubishi could become “entangled in a decades-long dispute involving issues of racial inequality and environmental justice,” the IEEFA report said.
Geismar residents are surrounded by about a half-dozen large chemical facilities that emit harmful levels of air pollution. Of the more than 6,000 people who live within the three miles of the planned project site, about 40% are Black or Hispanic, and 20% are considered low-income, according to federal data.
“The air here is already so dirty that the kids can’t play outside anymore,” said Pamela Ambeau, Ascension Parish resident and member of the group Rural Roots Louisiana.
The proposed plant is the latest in a string of failed industrial projects in Cancer Alley. Since 2019, local activism was instrumental in halting the development of two large plastics complexes in St. James Parish and a grain export terminal in St. John the Baptist Parish. All three projects would have been built in historically Black and rural communities.
Mitsubishi’s project had the strong backing of Louisiana political leaders. In 2020, then-Gov. John Bel Edwards, a Democrat, praised the project as a “world-scale” chemical manufacturing facility that would create “quality jobs.”
Louisiana Economic Development predicted the plant would create 125 jobs with an average salary of $100,000 and another 669 “indirect jobs” in the region.
The state agency began courting Mitsubishi in 2016, offering the company worker recruitment and training assistance and a $4 million grant to offset construction costs.
In 2021, Mitsubishi applied for property tax abatement via the state’s Industrial Tax Exemption Program, or ITEP. The tax relief, which Louisiana has granted to several similar projects, was pending the plant’s construction and would have saved the company an estimated $17 million in its first year, according to LED.
The first of a series of project delays began in 2022 due to what Mitsubishi called “market volatilities.”
Mitsubishi appeared to be betting on generous state subsidies “while ignoring the larger financial landscape,” said Tom Sanzillo, author of the IEEFA report.
The combination of sustained market weakness and strong public opposition “erased the potential benefits they are counting on,” he said.
Editor’s note: A new report that microplastics pollution is hampering photosynthesis in plants, and that the result is the loss of some 10% of the world’s primary productivity, including food crops. We are now risking to blot out the planetary photosynthesis machine, just because we think that stopping the growth of the plastics industry is a subversive idea. But the report gets something in reverse: it is not that these effects “extend from food security into planetary health.” It is the opposite .But that changes little in a situation in which nothing changes, except for the desperate attempt of solving problems by killing the messenger, that is, “driving a dagger into the climate change religion”
We got rid of acid rain. Now something scarier is falling from the sky. Here’s why you should never, ever drink the rain. A number of studies have documented microplastics in rain falling all over the world — even in remote, unpopulated regions. Plastic particles have infiltrated the entire planet, from the summit of Mount Everest to the deepest oceans. Also, the microscopic shards of plastic found in every corner of the planet may be exacerbating antibiotic resistance, a new study has found.
Plastic Pollution: So Much Bigger Than Straws
by Jackie Nuñez, The Revelator
March 14, 2025
Over the past couple of weeks we’ve seen the current U.S. administration grasping at straws, mocking restrictions on single-use plastics, and trying to distract from the real issue: Plastic poisons people and the planet, and the industries that produce it need to stop making so much of it.
When I started “The Last Plastic Straw” movement in 2011, the sole purpose was to bring attention to a simple, tangible issue and raise awareness about the absurdity of single-use plastic items and engage people to take action.
So what are the real problems with plastic? Plastics don’t break down, they break up: Unlike natural materials that decompose, they fragment into smaller and smaller pieces, never benignly degrading but remaining forever plastic. All plastic items shed plastic particles called microplastics and even smaller nanoplastics, which we inhale, ingest, and absorb into our bodies. Plastics, depending on their manufacturing composition, contain a mixture of more than 16,000 chemicals, at least 4,200 of which are knownhazards to human health. When we use plastic straws, cups, plates, utensils, and food packaging, we are literally swallowing those toxic plastic particles and chemicals.
Plastic particles have also been found in placenta and breast milk, so children today are being born plasticized. This is a toxic burden that today’s youth should not have to bear.
🧠 A new study found the amount of microplastics & nanoplastics in human brains increased by 50% between 1997 to 2024. Researchers found that in people with dementia, plastic particles were six times more numerous than in people without dementia. It was also found that plastic particles in human livers are increasing over time.
🔬75% of the plastics found in human tissue samples were one of the most common types of plastics: polyethylene. Polyethylene (PET) is used in everyday items like food packaging, bottles, bags, toys, and more.
📈 With microplastics and nanoplastics building up in our bodies it’s time to put plastic-free solutions in place, for people and the planet.

It goes without saying that plastic’s harms to our health come at an enormous cost to us, who must suffer through the heartbreaking and painful diseases it causes. It’s estimated that every 30 seconds, someone dies from plastic pollution in the Global South, an area overburdened by mountains of plastic pollution that is shipped away from the Global North under the guise of “recycling” only to be dumped and often burned, releasing additional toxic pollution. Financially too, plastics are expensive: The chemicals in plastic alone cost the U.S. healthcare system $250 billion in just one year.
We can’t recycle our way out of this. Plastic was never made to be recycled and is still not made to be recycled.
Our leaders who support continued or even increased plastic production seem ignorant of the facts about plastic pollution. Let us enlighten them: All plastic pollutes, and single-use plastic items like straws are not only hazardous to our health, they’re especially wasteful.
We could all save money if our government prioritized building up plastic-free reuse and refill systems, where we hold on to our stuff rather than continuously buy it and throw it away. Such reuse and refill systems were the reality before single-use plastic was mass-produced and marketed. And they worked. Most U.S. voters support reducing plastic production, along with national policies that reduce single-use plastic, increasing use of reusable packaging and foodware, and protecting people who live in neighborhoods harmed by plastic production facilities.
To change this nightmare scenario, our leaders need to support policies that reduce plastic production, not grow it. This means curbing wasteful plastic production and supporting plastic- and toxic-free, regenerative materials and systems of reuse and refill.
As the advocacy and engagement manager at Plastic Pollution Coalition, my work continues to support the solutions to this massive global crisis — strong policies that focus on plastic pollution prevention, better business practices, and a culture shift. We work together with our allied coalition organizations, businesses, scientists, notables and individual members every single day to make these solutions a reality — no matter how much the U.S. administration or other leaders try to undermine, belittle, or dismiss efforts to minimize the use of straws and other quickly disposed plastic products that poison our planet and our bodies.
Plastic never was and never will be disposable, and neither are people.

Editor’s note: “A new study in Science indicates that reforestation projects, which restore degraded or destroyed forests, are the most effective land-based method for carbon removal and biodiversity protection. Meanwhile, the authors found that afforestation, in which trees are added where they didn’t exist before, and bioenergy cropping, in which carbon-removing crops are planted to make biofuels, can have negative effects on wildlife, outweighing the benefits of carbon removal. The research highlights the importance of identifying the best places for reforestation projects, but the authors emphasize that reforestation is not a replacement for fossil-fuel reduction.”
Evidence suggests that allowing forests to regenerate of their own accord – a process known as “proforestation” – is a more effective, and perhaps more importantly, a more immediate way of sequestering carbon from the atmosphere than planting new forests. Coined by scientists William Moomaw and Susan Masino, the term basically means, in Moomaw’s words, “allow[ing] trees that are already planted, that are already growing, to continue growing to reach their full ecological potential, to store carbon, and develop a forest that has its full complement of environmental services.”
KARÈ, Togo — Under the hot sun of an April afternoon in northern Togo, we made our way by motorcycle across the impoverished prefecture of Kozah. It wasn’t a long journey, about 30 minutes, but threading between trucks and cars on National Highway No. 1, it was a treacherous one. When we arrived, we were greeted with a smile by “Dadja” Pékémassim Ali, the 57-year-old chief of the canton of Kouméa, where the village of Karè is located.
“We’re glad you’ve come to talk about this forest, whose restoration we’re delighted to see,” he told us. “Out of ignorance, and in a desire to satisfy our needs, our people set fire to the forest and cut down all the trees. And for years, we suffered from scarce rainfall, no timber, and even hotter temperatures. Our children no longer knew of the area’s birds and other animal species.”
Ali gave us his approval to climb Karè’s mountain and visit the sacred forest known as Titiyo forest. As we entered the forest, we were greeted by a cool breeze and the sound of birdsong.

Since the 1800s, the sacred forest of Titiyo has been the site of annual rituals that involve traditional dances and the celebration of various deities. People come from throughout the canton of Kouméa and the entire Kozah prefecture.
It’s also an area of biodiversity conservation. This ecosystem, vital for the Karè village community, has suffered severe degradation since 1992, in the wake of a political crisis in Togo. Pressure from a growing population led to its rapid destruction as trees were felled for charcoal, firewood and timber, reducing the forest to almost nothing.
“Ever since we destroyed this forest by cutting down the trees, and with bushfires, mainly for hunting, the rain stopped,” said Kossi Karani, a Karè villager. “And we suffer from that because it affects our agricultural yields. The animals had disappeared, as well as the birds. There was no more life in the forest.”
But today, this sacred forest persists and has even begun to recover, thanks to the determination of a son of Karè: Sylvain Tchoou Akati.
Akati said he remembers watching helplessly as Titiyo’s destruction began, when he was just 12 years old. The tragedy left such an indelible impression that it prompted him to start fighting to restore Togo’s forests.
“The destruction of our sacred forest of Titiyo is recent, it happened before my very eyes,” he told Mongabay. “It all started with a need for wood to put a roof on the village elementary school. The forest was gradually destroyed until 2005.”
Today, Akati is the executive director of an NGO based in the capital, Lomé, known as AJEDI, or Youth Action for Integral Development. Its mission is to support and coach local communities in sustainable development. Akati’s motivation for restoring his own village’s forest comes not just from his love of nature, but also from encouragement by his uncle, Anam, well known in Karè for his love of planting trees, notably teak and mango.
Although he left Karè in 1997 to pursue his secondary and university studies in Lomé, Akati never abandoned his love for Titiyo. He became an activist for the preservation of forest ecosystems and sustainable development, and founded AJEDI in 2008. A few years later, in 2015, he set about restoring his native village’s forest.
“I cannot allow Titiyo, this sacred forest, to disappear without me doing something about it, especially given climate change. So in 2015, I visited my father, who was still alive, to tell him of my intention to restore the forest that our grandfather was responsible for preserving,” he said.
Raising public awareness
But Akati said he knew he couldn’t do it alone. Through his NGO, he began rallying the members of his community.
“We organized a meeting in the public square, which was attended by people from the surrounding villages. I explained to them the environmental, cultural, economic and social importance of restoring our forest, which is part of our shared heritage,” Akati said.
“During the training, we were made aware of how restoring the forest can contribute to good rainfall and improve agricultural production,” Tchilalo Pitekelabou, a member of the project’s monitoring committee, told Mongabay. She was one of six people appointed to the committee by the community’s members after the meeting. “We were also made aware of how forest resources can make our lives easier. That’s why we became involved, both men and women, in the restoration of Titiyo.”
The awareness-raising campaign prompted the Karè villagers, especially its women, to commit to the restoration of the forest. “In the early years, we sometimes watered the seedlings in the dry season to ensure their growth,” Pitekelabou said.
People who owned land within the forest’s perimeter agreed to give up their plots for reforestation.
A helping hand from the government
In 2019, Akati presented his project to Togo’s Ministry of Environment and Forest Resources, receiving positive feedback.
“The forest had become highly degraded and consisted of just a few trees,” said Yawo Kansiwoe, the Kozah prefectural official responsible for water, forests and the environment. “The local population and authorities were desperate to find ways of restoring it. This is what caught the attention of the NGO, which held discussions with local officials to jointly determine how the forest could be restored. Sylvain Akati’s determination encouraged us to give our full support to the NGO in all its awareness-raising and reforestation activities.”
In 2019, the first year of reforestation, the environment ministry provided technical and financial support worth $5,702 to support the reforestation of around 3 hectares (7 acres), allowing the planting of 3,500 seedlings, including Khaya senegalensis, earleaf acacia (Acacia auriculiformis), melina (Gmelina arborea), African locust bean (Parkia biglobosa), baobab (Adansonia digitata), kapok (Ceiba pentandra) and neem (Azadirachta indica) trees.
“We chose these species because they are sacred. The baobab, kapok and African locust bean are sacred in this forest,” said Koudjabalo Ayouguele, AJEDI’s local representative for the Kara region, where Kozah prefecture is located. “But beyond that, we have also planted trees such as Khaya senegalensis, which will enable us to restore the forest quickly.”
After this first year, the rest of the reforestation work fell to Akati. But he was able to draw on the commitment of local authorities eager to see Titiyo restored.

New life makes the birds sing
“We are grateful to our son Tchoou, who had the idea of enlisting us to help restore this forest,” said Ali, the Kouméa canton chief who also serves as the primary guardian of the area’s traditions and customs. “In the beginning, there were a lot of us, but along the way some became demotivated because there was no money to be made straight away. But others like us, who understood the wider importance, remained determined. And we’ll never give up.
“Before, children didn’t know about the birds in this area, but with the restoration of the forest, we can show them all the types of birds here,” he added. “And we ourselves are happy, because the birds are singing in our ears again, something we haven’t experienced here for years with the disappearance of the forest.”
As well as birds, other animals have also found refuge in the Titiyo forest. “Thanks to this forest, a fresh breeze now blows through the village of Karè,” Akati said. “It’s like a microclimate. And there are monkeys, cane rats [Thryonomys swinderianus], reptiles like the boa [sic, boa constrictors are not native to Africa], the eastern green mamba [Dendroaspis angusticeps], vipers and snakes that have returned to the forest.”
On top of this, from a cultural perspective, the local people can now once more perform traditional rites with joy.
Kansiwoe, the prefectural official, said seeing the forest’s recovery is a source of great satisfaction: “We are delighted with the encouraging results of the restoration and recovery of this forest, which at its core is a sacred place, and preserves this sacred forest tradition.”
Now that the forest has begun to be restored, it’s time to consider how to maintain it.
“Protecting this forest remains a major challenge, and it is something we are working on,” Akati said. “For the time being, the watch committee is carrying out its mission well, which consists of monitoring the forest, making fire patrols, and continuing to raise awareness so we avoid bush fires and tree cutting. So far, thanks to their work, no bush fires have been recorded. We hope, thanks to their commitment and that of the population, to continue in this way.”
Beyond that, he pointed out a practice carried out by his grandparents, which could be a crucial asset.
“What we also want to do to help preserve the forest is to reinstate an old practice or law, which prohibited entering the forest in the rainy season and which everyone respected without question. This rule also prohibited entry into the sacred forest without authorization,” he said.
In search of support
To safeguard the Titiyo community forest, Akati also needs financial and technical support. He said establishing some income-generating activities linked to the forest should increase the chances of its preservation.
“Now, we need to find ways to preserve what we’ve achieved. We’re thinking of promoting beekeeping and market gardening, and building a multipurpose facility with a solar energy system. In the long term, in addition to beekeeping, we’re also thinking of developing nontimber forest products, given the species planted in the forest.”
With his commitment to restoring forest ecosystems, Akati is also looking for support to enable him to restore other sacred forests across Kozah prefecture. Now in his 40s, he’s already hard at work restoring the sacred forest of Landa, about 5 kilometers (3 miles) from Titiyo.
“It’s not just Titiyo that was threatened with extinction,” he said. “Our experience here can now help us restore all of Kozah’s sacred forests.”

Editor’s note: “In recent years, the Southeast Asian country of Vietnam experienced a boom in renewable energy investments driven by generous feed-in tariffs, under which the state committed to buying electricity for 20 years at above-market prices. However, the high tariffs increased losses for Vietnam’s state-owned power utility EVN, the only buyer of the generated electricity, and led to an increase in power prices for households and factories. Authorities have repeatedly tried to reduce the high tariffs. Now they are considering a retroactive review of the criteria set for accessing the feed-in tariffs.”
“It’s really hard to build wind farms in Arizona, and if you put this into place, it’s just pretty much wiping you out,” said Troy Rule, a professor of law at Arizona State University and a published expert on renewable energy systems. “It’s like you’re trying to kill Arizona’s wind farm industry.”
United States Congressional House Republicans are seeking to prevent the use of taxpayer dollars to incentivize what they describe as “green energy boondoggles” on agricultural lands, citing subsidies that could cost taxpayers hundreds of billions of dollars over the next decade.
They are expensive to build, just finding their footing on this side of the Atlantic, and have faced backlash from parties as varied as beachfront property owners and fishermen to coastal businesses and fossil fuel backers(most of the developers have fossil fuel ties).
The future of Humboldt County’s offshore wind industry appears increasingly uncertain following mass layoffs at RWE and Vineyard Offshore, the multinational energy companies leading efforts to develop commercial-scale floating wind farms on the North Coast. The job cuts come in response to widespread market uncertainty following President Donald Trump’s efforts to ban offshore wind development in the United States.
A critical permit for an offshore wind farm planned near the New Jersey Shore has been invalidated by an administrative appeals board.
COLOMBO — In a dramatic turn of events, Indian tycoon Gautam Adani’s Green Energy Limited (AGEL) has withdrawn from the second phase of a proposed wind power project in northern Sri Lanka. The project, which was planned to generate 250 MW through the installation of 52 wind turbines in Mannar in the island’s north, faced strong opposition since the beginning due to serious environmental implications and allegations of financial irregularities.
While renewable energy is a crucial need in the era of climate change, Sri Lankan environmentalists opposed the project, citing potential ecological damage to the sensitive Mannar region. Additionally, concerns arose over the way the contract was awarded, without a competitive bidding process.
The former government, led by President Ranil Wickremesinghe, had inked an agreement with AGEL, setting the power purchase price at $0.82 per unit for 20 years. This rate was significantly higher than rates typically offered by local companies. “This is an increase of about 70%, a scandalous deal that should be investigated,” said Rohan Pethiyagoda, a globally recognized taxonomist and former deputy chair of the IUCN’s Species Survival Commission.
Legal battles
Five lawsuits were filed against this project by local environmental organizations, including the Wildlife and Nature Protection Society, the Centre for Environmental Justice and the Environmental Foundation Ltd. In January, the newly elected government expressed its desire to cancel the initial agreement and to renegotiate its terms and conditions, citing the high electricity tariff. Environmentalists welcomed the decision, believing the project would be scrapped entirely. However, their relief was short-lived when AGEL clarified that the project itself was not canceled, only the tariff agreement.
Government spokesperson Nalinda Jayatissa later confirmed that the project would proceed after renegotiating a lower power purchase rate. However, two weeks later, AGEL announced its complete withdrawal from the project, a decision widely believed to be influenced by the government’s stance.
Wind energy potential
Sri Lanka has been exploring wind energy potential for more than two decades, with the first large-scale wind farm in Mannar named Thambapavani commissioned in 2020. This facility, comprising 30 wind turbines, currently generates 100 MW of power. With an additional 20 turbines planned, the Mannar wind sector would have surpassed 100 towers.
The Adani Group had pledged an investment totaling $442 million, and already, $5 million has been spent in predevelopment activities. On Feb. 15, the Adani Group formally announced its decision to leave the project. In a statement, the group stated: “We would respectfully withdraw from the said project. As we bow out, we wish to reaffirm that we would always be available for the Sri Lankan government to have us undertake any development opportunity.”
Environmentalists argue that Mannar, a fragile peninsula connected to the mainland by a narrow land strip, cannot sustain such extensive development. “If built, this project would exceed the carrying capacity of the island,” Pethiyagoda noted.
Mannar is not only a growing tourism hub, known for its pristine beaches and archaeological sites, but also Sri Lanka’s most important bird migration corridor. As the last landmass along the Central Asian Flyway, the region hosts millions of migratory birds, including 20 globally threatened species, he added.
Sampath Seneviratne of the University of Colombo, who has conducted satellite tracking research on migratory birds, highlighted the global importance of Mannar. “Some birds that winter here have home ranges as far as the Arctic Circle,” he said. His research has shown how extensively these birds rely on the Mannar Peninsula.
Although mitigation measures such as bird monitoring radar have been proposed to reduce turbine collisions, power lines distributing electricity remain a significant threat, particularly to species like flamingos, a major attraction in Mannar. The power lines distributing electricity from the already established wind farm near the Vankalai Ramsar Wetland and are already proven to be a death trap for unsuspecting feathered kind.
Nature-based tourism
Given Mannar’s ecological significance, conservationists say the region has greater potential as a destination for ecotourism rather than large-scale industrial projects. “Mannar’s rich biodiversity and historical value make it ideal for nature-friendly tourism, which would also benefit the local community,” Pethiyagoda added.
With AGEL’s withdrawal, Sri Lanka now faces the challenge of balancing its renewable energy ambitions with environmental conservation. However, there are other sites in Sri Lanka having more wind power potential, and Sri Lankan environmentalists hope ecologically rich Mannar will be spared from unsustainable wind farms projects.
