Turkey: the splendor of the Hagia Sophia, the ruins of Ephesus, and the bizarre caves of the Cappadocia. For foreign travelers, Turkey is a nation of cultural, religious, and historic wonders: a place where cultures have met, clashed, and co-created. However, Turkey has another wealth that is far less known: biodiversity. Of the globe’s 34 biodiversity hotspots, Turkey is almost entirely covered by three: the Caucasus, the Irano-Anatolian, and the Mediterranean. Despite its wild wealth, conservation is not a priority in Turkey and recent papers in Science and Biological Conservation warn that the current development plans in the country, which rarely take the environment into account, are imperiling its species and ecosystems.
“The current ‘developmentalist obsession,’ particularly regarding water use, threatens to eliminate much of what remains, while forcing large-scale migration from rural areas to the cities. According to current plans, Turkey’s rivers and streams will be dammed with almost 4,000 dams, diversions, and hydroelectric power plants for power, irrigation, and drinking water by 2023,” the authors write, adding that other threats include urbanization, wetland-draining, and poaching.
Turkey is particularly rich in plants: with over 9,000 recorded to date, a third of them are found only in Turkey. Amphibians and reptiles are also highly diverse with 150 species to date. And Turkey, even now, still retains some startling big mammals including the striped hyena (Hyaena hyaena), brown bear (Ursus arctos), gray wolf (Canis lupus), caracal (Caracal caracal), and Eurasian Lynx (Lynx lynx). But it has also lost nearly as many as it has retained, including cheetahs, lions, tigers, and aurochs.Turkey is also a hugely important bird country with over 500 species identified so far.”Turkey lies at the intersection of globally important bird migration flyways. It has the highest number of breeding bird species in the Europe, but also the highest number of threatened bird species in Europe,” co-author Cagan Sekercioglu, a Turkish ornithologist and ecologist, with Stanford, told mongabay.com. “Few people realize that the famous Rift Valley bird migration over Israel and into Africa, and the Rift Valley itself, begin in Turkey. Bird species of traditional farms are declining fastest in Europe but can still be found in large numbers in the bioculturally diverse rural communities of Turkey, particularly in the east. Among others, Turkey hosts globally important breeding populations of threatened white-headed ducks, Egyptian vultures, sakers, great bustards, and imperial eagles, and is a key stopover site for declining migratory bird species like sociable plovers.”But all of Turkey’s remaining species are facing threats. In 2012 the Yale Environmental Performance Index ranked Turkey in the bottom 8 percent for its biodiversity and habitat conservation efforts, putting Turkey in the same category as some of the world’s most troubled and impoverished countries, such as Haiti, Libya, Eritrea, and Iraq. But scientists warn that recent policy efforts could push Turkey, which is working to become an economic powerhouse, even lower.
“Turkey’s environmental laws and conservation efforts are eroding, not improving. This has precipitated a conservation crisis that has accelerated over the past decade. This crisis has been exacerbated by legislative developments that may leave Turkey with a nature conservation legal framework that is weakened and severely out of line with globally accepted principles,” scientists wrote recently in separate letter in Science.Loose laws, poor enforcement, and little public oversight has created a situation whereby the Turkish government is capable of steamrolling any environmental concerns.”The government, practically unopposed, easily modifies existing laws and passes new ones to remove any environmental obstacles to the construction of dams, mines, factories, roads, bridges, housing projects, and tourism developments. Such construction increasingly occurs in ‘protected’ areas, often at the expense of local people,” the authors write.
The biodiversity loss caused by climate change will result from a combination of rising temperatures and predation — and may be more severe than currently predicted, according to a study by University of British Columbia zoologist Christopher Harley.
The study, published in the current issue of the journal Science, examined the response of rocky shore barnacles and mussels to the combined effects of warming and predation by sea stars.
Harley surveyed the upper and lower temperature limits of barnacles and mussels from the cool west coast of Vancouver Island to the warm shores of the San Juan Islands, where water temperature rose from the relatively cool of the1950s to the much warmer years of 2009 and 2010.
“Rocky intertidal communities are ideal test-beds for studying the effects of climatic warming,” says Christopher Harley, an associate professor of zoology at UBC and author of the study. “Many intertidal organisms, like mussels, already live very close to their thermal tolerance limits, so the impacts can be easily studied.”
At cooler sites, mussels and rocky shore barnacles were able to live high on the shore, well beyond the range of their predators. However, as temperatures rose, barnacles and mussels were forced to live at lower shore levels, placing them at the same level as predatory sea stars.
Daily high temperatures during the summer months have increased by almost 3.5 degrees Celsius in the last 60 years, causing the upper limits of barnacle and mussels habitats to retreat by 50 centimeters down the shore. However, the effects of predators, and therefore the position of the lower limit, have remained constant.
“That loss represents 51 per cent of the mussel bed. Some mussels have even gone extinct locally at three of the sites I surveyed,” says Harley.
Meanwhile, when pressure from sea star predation was reduced using exclusion cages, the prey species were able to occupy hotter sites where they don’t normally occur, and species richness at the sites more than doubled.
“A mussel bed is kind of like an apartment complex — it provides critical habitat for a lot of little plants and animals,” says Harley. “The mussels make the habitat cooler and wetter, providing an environment for crabs and other small crustaceans, snails, worms and seaweed.”
These findings provide a comprehensive look at the effects of warming and predation, while many previous studies on how species ranges will change due to warming assume that species will simply shift to stay in their current temperature range.
Harley says the findings show that the combined effects of warming and predation could lead to more widespread extinction than are currently predicted, as animals or plants are unable to shift their habitat ranges.
“Warming is not just having direct effects on individual species,” says Harley. “This study shows that climate change can also alter interactions between species, and produce unexpected changes in where species can live, their community structure, and their diversity.”
Editor’s note: When you invent nuclear energy (nukes) you invent radioactive waste
Some proponents of nuclear energy refuse to give up on the technology. They blame the decline in nuclear energy and the high costs and long construction periods on the characteristics of older reactor designs, arguing that alternative designs will rescue nuclear energy from its woes. In recent years, the alternatives most often advertised are small modular (nuclear) reactors—SMRs for short. These are designed to generate between 10 and 300 megawatts of power, much less than the 1,000–1,600 megawatts that reactors being built today are designed to produce.
For over a decade now, many of my colleagues and I have consistently explained why these reactors would not be commercially viable and why they would never resolve the undesirable consequences of building nuclear power plants. I first started examining small modular reactors when I worked at Princeton University’s Program on Science and Global Security. Our group largely comprised physicists, and we used a mixture of technical assessments, mathematical techniques, and social-science-based methods to study various problems associated with these technologies. My colleague Alex Glaser, for example, used neutronics models to calculate how much uranium would be required as fuel for SMRs, which we then used to estimate the increased risk of nuclear weapons proliferation from deploying such reactors. Zia Mian, originally from Pakistan, and I showed why the technical characteristics of SMRs would not allow for simultaneously solving the four key problems identified with nuclear power: its high costs, its accident risks, the difficulty of dealing with radioactive waste, and its linkage with the capacity to make nuclear weapons. My colleagues and I also undertook case studies on Jordan, Ghana, and Indonesia, three countries advertised by SMR vendors as potential customers, and showed that despite much talk, none of them were investing in SMRs, because of various country-specific reasons such as public opposition and institutional interests.

The mainstream view of the current climate crisis is that it is mainly caused by greenhouse effect from gases released by burning of fuels such as coal and oil. But there is another theory of man-made climate disaster that is hardly ever mentioned in the mainstream media. That is the theory that much of the anthropogenic change in climate in the last 60 years or so is due to the introduction of nuclear power.
Between 1949, when the atomic bomb testing program began, and 1963, when the atmospheric test ban treaty went into effect, over 1,000 atomic bombs (nukes) were set off above ground. Since 1963, many more have been set off underground, and ever single one of them has resulted in leakage of radioactive gases into the atmosphere. That’s right! They have never yet managed to set off an underground test that did not leak.
Nuclear explosions are one source, but only one, of a radioactive gas called Krypton 85, which is not found naturally in the atmosphere except in insignificant trace amounts. There is now several million times as much in the atmosphere as in 1945 at the start of the Atomic Age.
Kr85 has a half-life of only around 12 years, so much of it would be gone now if bomb tests were the only source for it. But it is also produced by the recycling of nuclear reactor fuel rods. During the recycling process 100% of the Kr85 is released into the atmosphere with no attempt at containment because since it goes up into the upper atmosphere where it cannot contact any living thing, it is considered biologically harmless.
Kr85 is a radioactive gas. Radioactive gases consist of charged particles. When charged particles enter the field of a magnet, they migrate toward the poles of the magnet. The earth is a giant bar magnet. The charged particles of the radioactive gas, Kr85, end up at the North and South Poles.
Tropical storms like hurricanes form along the equator. Such storms are highly-charged systems. How far they travel from their birthplace along the equator toward the pole is determined by how strongly charged they are and how strongly charged the pole of the earth is that attracts them.
As charge from Kr85 builds up at the poles, more and more tropical storms are attracted farther and farther toward the poles, bringing tropical heat with them, causing warming of the temperate and polar regions. At the same time, the temperate zones experience more frequent and more severe tropical-type storms. The storm surges from these storms send high water marks higher, eroding coastlines and giving the impression of rising sea levels.
The build-up of radioactive gas at high altitude in the polar regions interacts with the influx from space that enters the earth at the poles and is known as the Wilson Current. This energetic stream then flows through the crust of the earth in huge surges, and is discharged back into space in the form of upward-striking lightning bolts as a part of the nearly constant belt of thunderstorm activity that circles the earth at the equator. The whole process is known as the Wilson Circuit, and it is the balance of inflow from space at the poles and discharge into space as lightning that maintains the electrostatic balance of the earth.
The ionization of the upper atmosphere at the polar regions, making the atmosphere more conductive, bleeds off a portion of the inflowing Wilson Current and the result is less lightning on a global basis. According to carefully-maintained insurance company statistics, the number of claims for lightning-related damage was steady from the 1830s until about 1950 and has since declined by about 35%, indicating a drastic decrease in lightning all over the earth.
Since lightning is the most important mechanism in nature by which atmospheric nitrogen is “fixed” into nitrogen compounds plants can utilize, and some species of plants are more dependent on lightning for their nitrogen needs than others, this would have a transformative effect on the composition of ecosystems, leading to a decrease in biodiversity as the most lightning-dependent species decline and other species, less dependent on lightning-produced nitrogen, succeed them in the ecosystem.
This subtle effect, changing the ratio of one plant species to another, is not likely to be noticed, and if noticed, is not likely to be ascribed to a cause so remote as a build-up of radioactive gas at the North or South Poles from nuclear plants scattered all over the industrialized regions of the world. But that is a perfect example of how closely connected and interdependent the natural world really is. And this effect is one of the most important consequences of the development of nuclear technology.
These are only some of the effects of nuclear power that are seldom if ever addressed by the mainstream anti-nuclear movement, and which MUST be addressed if the full costs of the nuclear age are to be understood.

Speaking at a media briefing to raise awareness on the importance of accountability when such maritime disasters occur, Anita Perera, Campaigner for Greenpeace South Asia, said that when a team visited Mannar on June 19, they noticed a significant number of plastic pellets even after one round of cleanup operations. “The Mediterranean Shipping Company (MSC) is responsible for cleaning up the oil spill, but so far, they haven’t communicated their response to expedite the cleaning of nurdles or the oil spill. This isn’t an isolated incident but a result of deeper structural failures in how we are governing our oceans and environmental safety. These are critical ecosystems, and there are people(and all of the other species) whose daily livelihoods would be affected as a result of such disasters. We need to hold these companies accountable for such incidents,” she underscored.
COLOMBO — Sri Lanka is once again facing a significant marine environmental crisis, as tiny plastic pellets, commonly known as nurdles, have begun washing ashore along the island’s northern coastline. This time, the pollution is linked to the sinking of the Liberia-flagged container ship MSC ELSA 3 off of Kerala, India. The unfolding incident has triggered fears of a repeat of the X-Press Pearl disaster in 2021, the worst maritime disaster to have occurred in Sri Lanka, significantly impacting marine ecosystems and coastal communities.
According to the Indian Coast Guard, the MSC ELSA 3, carrying 640 containers including hazardous cargo, sank on May 25, roughly 38 nautical miles off the Kerala coast. The cause was reportedly a failure of its ballast system. Indian authorities confirmed the vessel was loaded with an estimated 85 metric tons of diesel and 367 metric tons of furnace oil, in addition to at least 13 containers of dangerous substances such as calcium carbide. All 24 crew members were safely rescued by Indian Coast Guard and Navy teams.
While Indian authorities were able to initially contain an oil spill, the environmental fallout soon escalated. Plastic nurdles released from sunken containers began appearing on beaches in southern India, and by June 11, ocean currents driven by strong gusts of southwest monsoon winds carried them toward Sri Lanka’s northern shores, raising serious concerns among marine biologists and local communities.

Fresh environmental fallout
“We’ve begun cleaning efforts and are evaluating coordinated response actions,” said Padma Abeykoon, additional secretary at the Ministry of Environment. With strong monsoon winds forecast for the coming days, she noted that ocean currents may bring even more pollutants ashore.
According to Abeykoon, Indian authorities had alerted Sri Lanka about the possibility of debris from the sunken vessel drifting toward its shores, depending on ocean current patterns. The plastic pellets first arrived on the northern islands and reached the Mannar coast within a day, continuously washing up along Sri Lanka’s southern-facing beaches.
One of the earliest reports from Sri Lanka came from Lahiru Walpita, a birdwatcher in Mannar, who observed the nurdles during his routine early morning seabird monitoring. “On June 12, I noticed strange white pebbles scattered across the Mannar beach. A closer look revealed they were plastic nurdles, something I sadly recognize from the X-Press Pearl spill,” Walpita said.
Walpita initially assumed the rough seas had opened up a remnant of X-Press Pearl, but as he discovered 20 25-kilogram (55-pound) bags of nurdles strewn across a 2-kilometer (1.2-mile) stretch of beach in Mannar, he realized something was wrong. Out of these, only two bags were damaged, and others were in perfect shape, Walpita told Mongabay.
Walpita also observed crows and an egret investigating the pellets but hadn’t consumed them. “However, seabirds, like little terns and bridled terns, feed off the ocean surface while in flight and I fear they could mistake these pellets for food as they have little time to observe,” he warned. The breeding season for these species, especially on tiny islands nearby in Adam’s Bridge Marine National Park, runs from May to September, and Walpita fears the nurdle invasion could disrupt their reproductive cycles.

Temporary fishing ban
Meanwhile, Indian authorities imposed a temporary fishing ban within 20 nautical miles of the MSC ELSA 3 wreck to mitigate risks from hazardous cargo. One of the most concerning chemicals on board was calcium carbide, which reacts violently with water to release acetylene — a highly flammable and potentially explosive gas — and produces caustic substances harmful to marine life.
Adding to the urgency, Indian authorities are battling another maritime emergency just two weeks after the ELSA 3 incident. On June 7, the Singapore-flagged container ship MV Wan Hai 503 caught fire following multiple explosions, approximately 88 nautical miles off the coast of Kerala. The vessel, carrying more than 2,128 metric tons of fuel and numerous containers with hazardous materials, poses a potentially greater environmental risk than ELSA 3. As of June 18, Indian Coast Guard reports indicated that the fire was under control. The drifting vessel has since been secured and successfully towed away.

Nurdle spill
The nurdles are highly persistent in the marine environment, as they can absorb toxic chemicals and enter the food chain, posing a risk to marine life and potentially humans as research on the aftermath of X-Press Pearl disaster proves.
The parallels of these disasters with the X-Press Pearl disaster are striking. The 2021 incident released billions of nurdles into the Indian Ocean, contaminating beaches for months, killing marine organisms and disrupting fishing livelihoods. One silver lining is that a lot of research was conducted following the X-Press Pearl disaster, and this can be informative in tackling the ongoing episode of the nurdle pollution, Gunasekara said.
Even today, Sri Lanka is fighting for adequate compensation, with legal proceedings dragging on in international courts. The echoes of that catastrophe now serve as a grim warning: Unless stronger regional protocols and maritime safety measures are enforced, the region could be doomed to repeat history.

Editor’s note: The International Day for Biodiversity was celebrated on May 22, which commemorates the adoption of the Convention on Biological Diversity, a global treaty. What lessons have we learned from undoing past harms and conserving biodiversity for our planet’s future?
Global efforts to restore forests are gathering pace, driven by promises of combating climate change, conserving biodiversity and improving livelihoods. Yet a recent review published in Nature Reviews Biodiversity warns that the biodiversity gains from these initiatives are often overstated — and sometimes absent altogether.
Restoration has typically prioritized utilitarian goals such as timber production, carbon sequestration or erosion control. This bias is reflected in the widespread use of monoculture plantations or low-diversity agroforests. Nearly half the forest commitments in the Bonn Challenge to restore degraded and deforested landscapes consist of commercial plantations of exotic species, a trend that risks undermining biodiversity rather than enhancing it.
Scientific evidence shows that restoring biodiversity requires more than planting trees. Methods like natural regeneration — allowing forests to recover on their own — can often yield superior biodiversity outcomes, though they face social and economic barriers. By contrast, planting a few fast-growing species may sequester carbon quickly but offers little for threatened plants and animals.
Biodiversity recovery is influenced by many factors: the intensity of prior land use, the surrounding landscape and the species chosen for restoration. Recovery is slow, often measured in decades, and tends to lag for rare and specialist species. Alarmingly, most projects stop monitoring after just a few years, long before ecosystems stabilize.
Scientists underline that while proforestation, reforestation and forest rewilding can contribute to curbing climate change and biodiversity loss, they have their limits and must be combined with deep carbon emissions cuts and conservation of existing forests and wilderness.
Edward Faison, an ecologist at the Highstead Foundation, stood quietly in a patch of forest that stretched for miles in all directions. Above him, the needles from white pine trees swayed — common in the Adirondack Forest Preserve in northern New York state. He stepped past downed wood and big, broken snags, observing how the forest functioned with minimal interference.
“These forests have been essentially unmanaged for over 125 years. To see them continue to thrive and accumulate carbon, recover from natural disturbances and develop complexity without our help reveal just how resilient these systems are,” Faison says.
Protected from logging in 1894 by an act of the New York Legislature, the Adirondack Forest Preserve (AFP) is a model of natural forest growth, or letting forests simply “get on with it.” The largest trees, white pines (Pinus strobus), are more than a century old and stretch more than 150 feet tall and are 4-5 feet in diameter.
The AFP, the largest wilderness preserve in the eastern United States, is a prime example of what researchers have come to call “proforestation.” Coined in 2019 by Tufts University professor William Moomaw and Trinity College professor of applied science Susan Masino, the term proforestation describes the process of allowing existing forests to continue growing without human interference until they achieve their full ecological potential for carbon sequestration and biological diversity.
Proforestation is considered a natural climate solution, i.e., a strategy to steward the Earth’s vegetation to increase the removal of carbon dioxide (CO2) from the atmosphere. According to Faison, a forest naturally develops greater complexity over time, with a diversity of tree sizes and heights as well as large standing dead trees and downed logs. This complexity provides habitat for various animals, plants and fungi, which make the forest more resilient to disturbances associated with climate change.
Proforestation is distinct from reforestation, which can involve planting new trees in deforested areas to restore them (or allowing deforested areas to naturally regenerate). It is also different from afforestation, which is the process of planting new forests in previously unforested areas. Proforestation’s merit lies in inaction: simply leaving old forests undisturbed, allowing for continuous growth to maximize carbon accumulation over time. As forests mature and trees grow larger, they sequester greater amounts of carbon.
“The largest 1% diameter trees in a mature multiage forest hold half the carbon,” according to Moomaw. “It’s the existing forests that we have that are doing the work.” Existing forests remove almost 30% of CO2 from the atmosphere that humans put in every year from burning fossil fuels.
Older is better
In Mohawk Trail State Forest in Massachusetts, Moomaw studied the tallest grove of white pine trees in New England, aged between 150 and 200 years, observing how the trees grew. When comparing them with younger trees of the same type growing under similar conditions, he found that “the amount of carbon added by these trees between 100 and 150 years of age is greater than the amount added between zero and 50.”
In addition to carbon storage capabilities, old forests are pivotal in controlling regional and global water cycles through a process called evapotranspiration, by which water is transferred from the land to the atmosphere. Due to deeper and more complex root systems as well as larger canopies and leaves, old forests capture more water and release it as vapor into the atmosphere.
“Old forests have the genetic competence to do this work,” Masino says. “It’s not done by meadows. It’s not done by grassy areas. It’s not done as effectively by forests that have been cut or planted. It’s these ancient systems that have the complexity to bring water to themselves. And in doing that, they’re bringing it to the rest of the landscape. Once you start cutting the landscape, you’re drying it out.”
Masino, who also has a joint appointment in neuroscience and psychology at Trinity College, emphasizes the importance of designating natural areas appropriately and allowing more room for proforestation.
“It’s urgent to decide where we intend to prioritize natural processes, where we are doing research, and what areas we are dedicating for our resource needs,” she says. “Nature needs room to breathe. We can’t leave everything open to manipulation and extraction. It’s deadly.”
She says that planting trees on streets, on campuses or in parks is good for temperature regulation, flood protection and creating habitat, but these trees don’t grow up in a web of life. Planting trees in a forest, too, can risk disrupting the dynamic complexity of evolved and evolving genetic knowledge.
Wildlife dependent on old growth
Over on the West Coast, University of Oregon professor emeritus Beverly Law has studied forests for decades. She describes watching three logging trucks, each with a giant log from an old, single tree strapped to the back, passing in a procession while waiting at an intersection on her bike, a frequent occurrence on her way to work at the university in the late 1980s.
“There are plant and animal species that rely on these old forests for their survival. You take away the forest, and they’re gone,” Law says. “It’s important to have diverse genetics in the forest. Some of them will be more genetically able to withstand climate change than others. You don’t know which ones they will be. That is why genetic diversity within species is important.”
Mature forests are crucial to the survival of certain critically endangered animals that rely on the connected canopies or the soil-rich forest floor. Preserving the biodiversity of the Pacific Northwest, which hosts forests more than a thousand years old, is especially dire. According to a 2022 paper published in Environmental Chemistry Letters, old growth forests retain a number of species from both the top and bottom of the food chain, such as the Olympic salamander (Rhyacotriton olympicus), the Del Norte salamander (Plethodon elongatus) and the two species of tailed frog (Ascaphidae). Losing them forever could kick off a cascade effect and result in severe consequences for the environment.
The spotted owl (Strix occidentalis), too, depends on old-growth forests in the Pacific Northwest, requiring the specific environment for roosting and nesting, and remains a central figure in forest management debates.
Such hulking ancient trees are the eyes of the woods, having stood through changing years and the changing climate.
“Ten to 12% of old-growth forests are left [in the US], and it’s insane that people are still trying to cut them down,” Law says. “They are the only survivors of American handiwork. Is it man’s dominion over the forest? We should have reverence, considering they’re all that’s left.”
