PARIS : If you're planning a hike in the mountains soon and feel the urge to pick up rocks, pile them up and post your creation on Instagram, think again.
This trend, known as 'rock balancing,' 'cairns,' 'rock stacking' or 'stone stacking' may be all the rage on Instagram, but it can have very real consequences for the flora and fauna that populate mountain waterways.
Back in 2020, Australian ecologist Nick Clemann, issued a warning about the dangers of such formations to a particular skink lizard in a report by Australian media outlet ABC News.
In Australia and elsewhere in the world, rocks form the habitat of these small reptiles and other animal species. Moving them therefore means depriving them of their shelter, which can directly threaten their survival.
In France, too, the practice is being called out. In 2022, the website of the Parc national des Calanques, a national park located on the Mediterranean coast in Southern France, published a press release sounding the alarm.
A number of animal and plant species in this sublime natural setting – but heavily affected by overtourism – are suffering as a result of rock stacking, notably the Tarentola mauritanica, or common wall gecko, the European yellow-tailed scorpion and the Sabline de Provence, a plant endemic to the region.
But that's not all: 'By removing stones along a pathway, the soil is left bare, leading to severe erosion until the bedrock is reached,' the news release explains.
While the release states that its aim is to raise awareness rather than punish what appears to be a harmless act, it nevertheless points out that building cairns in the park can result in a fine of €135.
National parks and mountain trails are not, of course, the only ecosystems affected. Picking up, moving, or stacking rocks or pebbles is punishable by a fine of €1,500 along the entire French coastline, as the government explains on its official website.
Meanwhile, in the past month, the issue has been brought to the fore once more, with tourists and locals in the area of Lake Tekapo, New Zealand speaking out about the practice.
While on this particular site, there is some disagreement about its direct impact on the ecosystem, the practice is being criticised for its disruption of the natural setting.
Described as 'environmental vandalism' by one resident in a report by Radio New Zealand, it's yet another example of tensions surrounding sites of natural beauty and how they are being affected by social media-driven tourism.
While it is obviously not forbidden to capture the breathtaking landscapes that you sometimes discover after hours of walking, there are practical and simple ways to enjoy the wonders of nature without harming it.
National parks and other marked trails are generally subject to strict regulations, which are posted on signs in strategic locations for visitors. You should always read these carefully before setting off on a walk.
Another golden rule to help you preserve the biodiversity of the place you're exploring is to 'leave nothing but footprints.' This advice applies to litter, building cairns, and even lovers who might be tempted to carve their initials into a tree or rock!
The 'leave-no-trace' principle of outdoor exploration is also espoused by experts in the US, cited in a recent article, who have labelled the proliferation of cairns an aspect of 'visual pollution' in a natural landscape.
Furthermore, cairns may have an important meaning in certain cultures whether as a traditional wayfinding approach or imbued with spiritual meaning, and thus stacking stones 'for fun' can potentially be seen as creating confusion or even offensive.

Rising tourism sparks environmental concerns in Croatia
With its rugged coastline, pristine waters and more than a thousand inlets and islands, Croatia has seen a tourist boom in recent years. Last year alone, more than 20 million visited the Balkan nation, much of which stretches along the Adriatic Sea. But the environmental impact of tourism on the nearly 6,000km coastline and marine life is troubling experts – and prompting calls for action. Sakarun beach on Dugi Otok island is often called 'Croatia's Caribbean'. Tourist boats drop anchor in the turquoise waters of the bay and head for its white sands. Some visitors complained, however, about unsightly swathes of Posidonia or dark Mediterranean seagrass on the shore, which led to its removal. The heavy machinery involved also removed sediment, resulting in the gradual disappearance of the sandy beach over the last decade. Croatia only has only a small number of sandy and pebble beaches, while the rest are rocky. Pikelj says that it is important to the environment as well as to the community to protect 'the sand that we have'. 'We don't have many sandy beaches so it's important that the sand we have is protected,' said geologist Kristina Pikelj, from Zagreb University Faculty of Science. In 2021, she launched a project to monitor Sakarun, and to educate locals and tourists about the vital role played by the so-called 'lungs of the sea'. Posidonia – a key store of carbon and producer of oxygen – is critical to slowing the effects of climate change, as well as being vital for marine habitats and providing an erosion buffer for the beaches. For the past three years Posidonia, which was once used as a vineyard fertiliser, has been left on the beach, spread apart in piles. 'We understand the tourist aspect, to show them the sand, this bay is beautiful and people really enjoy it,' said Pikelj. Marija Meklav, one of three people participating in the fieldwork at Sakarun, added: 'We are trying to raise public awareness and achieve something directly through field and laboratory work. 'Our generation can achieve something in this regard,' the 24-year-old student said. Artificial beaches With tourist numbers growing, local authorities have been expanding beach capacity for tourists in search of sun, sea and sand. At some locations so-called beach nourishment – adding sediment to repair natural erosion – has been carried out. But the technique has also been used to cover natural rocky parts with gravel or even concrete. During winter, the sea carries it away, meaning the costly process has to be repeated every season Dalibor Carevic, from Zagreb University Faculty of Civil Engineering said in places like Primosten, often called 'the town of beaches' on the central coast north of Split, the practice has gone too far. Experts repeatedly warned against the removal of hundreds of metres of rocks along one of its central beaches. The rocks were ground and mixed with quarry stones to make an artificial pebble beach that opened in 2011, with the process repeated every year. In less than a decade the coastline at the Mala Raduca beach has shifted by some 20m towards the sea, satellite pictures show. Municipalities have created artificial beaches like Primosten to accommodate the growing number of tourists. Primosten's veteran mayor Stipe Petrina, though, said beach nourishment was essential for a town dependent entirely on tourism. 'One cannot have a capacity for 15,000 people and beaches for 2,000,' he said, comparing it with a ski resort that hosts thousands of skiers but only offers a few hundred metres of slopes. When tourism started to take off in the 1960s, locals ground rocks to make access to the sea easier. 'Once there were vineyards here that could have remained but we would have all emigrated. The question is what is better,' said Petrina. 'In another Primosten bay there are rocks but I cannot see many tourists there,' Petrina said. The town of 2,800 people hosted nearly 90,000 tourists last year, mostly between July and August. In early May, German tourist Karin Hoggermann watched trucks bringing new gravel to prepare the beach for the season. 'For swimming and going in the sea, for kids, it's better that they repair the beach. Tourists would not come if they would not do that,' she said. Conquest of the sea Unlike in Italy, Spain, the Netherlands or France, which also use beach nourishment, few rivers flow into the Adriatic Sea off Croatia, making its ecosystem more vulnerable as it is less accustomed to additional sediment input. Excessive construction even in protected marine areas, concreting, non-compliance with regulations and huge fleets of charter boats also take their toll. The number of car parks, marinas, ports and roads are also growing. One long-term solution is to raise awareness among locals and authorities as well as education, experts said, urging consultation for more sustainable solutions. 'That conquest of the sea is not good and should be discouraged,' said Carevic. – AFP

If you're eating too fast, maybe it's time to rethink your meals
Eating more slowly can be encouraged with structured, varied meals, eaten with cutlery. (Envato Elements pic) PARIS : Wolfing down food too quickly is not without consequences for your health. Indeed, this eating habit is linked to an increased risk of obesity, cardiovascular disease and even certain types of cancer. But do you really need to force yourself to slow down, or could you simply structure your meals differently? Researchers at Japan's Fujita Health University set out to investigate. Over a 12-week period, they monitored 41 adults, all members of the university staff, and gave them three types of meal. These were either a slice of pizza warmed in the microwave, eaten by hand, or bentos consisting of rice, broccoli and chopped steak, eaten with chopsticks – sometimes starting with the vegetables, then sometimes saving them for last. The scientists' aim was to find out whether the speed with which one eats depends more on the type of food they eat or the order in which they eat it. Their findings, published in the journal Nutrients, speak for themselves. Bento meals resulted in significantly longer chewing times than pizza, regardless of whether the vegetables were eaten first or last. On average, participants took 182 to 216 seconds longer to finish their bento. In other words, it wasn't the order in which the food was eaten that slowed the pace, but rather the format of the meal. But that's not all. The bentos also encouraged participants to chew more often and faster – without changing the number of bites. This appears to have happened because a compartmentalised meal, served with utensils and composed of a variety of foods, naturally encourages people to slow down. Clearly, a meal that requires a certain level of effort is a meal that can be enjoyed more slowly. The scientists found no association between body mass index and meal duration. On the other hand, age and male sex seem to be associated with faster mealtimes. Much more than one's personal self-discipline, it could be the format of a meal – its composition, its presentation, the way it's eaten – that influences how quickly one eats it. So, rather than forcing yourself to slow down, it could be a question of giving yourself the means to do so naturally. In short, eating more slowly isn't (just) a matter of self-control: it's a choice that starts in the kitchen. It means foregoing quick, on-the-go meals and favouring structured, varied meals, eaten with cutlery. This could well be one of the simplest and most effective tools to combat overeating. Indeed, eating better could actually be a question of eating differently – taking your time, savouring each mouthful and sharing a moment with friends or family, for example. Reframing mealtimes in this way could help foster a more conscious, more serene and healthier way of eating.

3 generations of dolphins spotted off Israeli coast in rare sighting
JERUSALEM, June 4 (Xinhua) -- Israeli marine researchers have documented a rare sighting of three generations of bottlenose dolphins swimming together in the Mediterranean Sea off the coast of Tel Aviv, the University of Haifa said in a statement on Wednesday. The group included a grandmother, her daughter, and a newborn calf -- all belonging to the Tursiops truncatus species, commonly known as the bottlenose dolphin. The sighting was captured during a routine weekly marine survey, part of a long-running study by the university's Mediterranean research station in partnership with Delphis, a non-profit organization focused on marine mammal conservation. According to the researchers, it is the first time in 25 years of ongoing observation that a three-generation dolphin family has been photographed together in Israeli waters. The common bottlenose dolphin is the most frequently sighted species along Israel's coastline, with a local population estimated at around 360. While not classified as endangered, researchers say consistent monitoring remains critical. The grandmother dolphin, already familiar to the team, was previously recorded with calves in 2018 and 2021, underscoring the continuity of reproductive behavior in this small coastal population. Researchers noted that relatively few calves are identified after separating from their mothers, making the latest sighting a rare and valuable contribution to the long-term dataset.
