The housing crisis in the Pyrenees opens the debate on the limits of camping

by

“I am a temporary worker and I come to work in the Tena Valley. The rents are 800 euros and I am not going to share a flat. I prefer to live in the van with my cat (…) I don’t understand why they focus on me when I don’t break the regulations.” The words are those of an indignant woman. One to which the Civil Guard demands movement when it understands that it is camping illegally. One that, if what is said in the video is true, is completely right and the regulations are on its side. What happened? The video is brought to X by a user of the social network and in it you see a woman who, between irony and indignation, explains that she works as a seasonal worker in the Tena Valley (Huesca), that she lives in her van and that the Civil Guard is asking her to leave because, supposedly, she is camping. The video shows the conversation between the woman and one of the agents. He defends that “it’s been going on for a month and a half now” and that “that can be considered camping.” She, for her part, alleges that she does not take any items outside and that she also moves, which the agent also acknowledges. “Rents are 800 euros”. In her video, the protagonist points out that the cost of housing is very high in the Tena Valley and that she does not want to share a flat. “I prefer to live in the van with my cat,” he emphasizes. The truth is that this enclave right next to the Pyrenees is very tense. In fact, it was only a few months ago that he was born. Decent Housing Viello Aragón in defense of access to housing in this Aragonese area. They point out that the area is full of tourists. The problem is not just a matter of underused second homes. The group points out that the European funds dedicated to sustainable tourism are causing the attraction of more and more visitors with the conversion into apartments and houses as rural complexes, which worsens the conflict. They defend that it should be stopped the delivery of new licenses for tourist use, they propose the creation of a public housing pool, declaring the region as a stressed area in order to control prices and punish the owners of more than four residential properties who have empty homes. The final objective is to facilitate access to housing and so that the economy can diversify so as not to live solely on tourism. Yes, the law is on your side (sort of). The truth is that if the author of the video complies with what she says, the law is on her side. As explained by the colleagues of Motorpassionthere are no regulations that specify a maximum time in which a person can spend the night in their car. Because camping in a place not authorized for it is illegal but spending the night is allowed. The PROT Instruction 2023/14 It is the one that collects these differences. It states that “parking is not camping” as long as: That the vehicle, with the engine stopped, is only in contact with the ground through the wheels (stabilizing legs or any other device is not used, except for chocks, provided for by the General Traffic Regulations). That the vehicle does not occupy more surface area than what it occupies when closed, that is, without the deployment of projectable elements, chairs, tables, etc., elements that can invade a surface larger than that delimited by the perimeter of the vehicle, understood as the plan projection of the same. That the vehicle does not emit any type of fluids or noises to the outside. One but. And then, the instruction also states the following: All of the above will be understood without prejudice to the powers of the town councils, through their municipal regulations, to limit or regulate, without discrimination based on the type of vehicle, the stopping and parking points under criteria of physical organization of traffic, commerce or environmental criteria, or with the purpose of favoring the arrival of this type of motorhome tourism, establishing for this purpose, parking zones or areas or, where appropriate, camping. Likewise, the regional regulations that have been approved or could be approved for the purpose of tourism promotion in the national territory will be taken into account. to promote a new type of accommodation that in any case will coexist with the full application of national legislation on traffic and road safety and especially the regulations relating to stopping and parking maneuvers. The matter here is a little more delicate because the video does not explain the situation regarding any of these concepts. What the instruction makes clear is that the City Council can delimit where a motorhome can park. In the images it appears that the van is located on the outskirts of a town but it is not clear whether or not the vehicle may be parked there, specifically. Without knowing the municipality, we also do not know if the town’s mobility ordinance imposes a maximum parking time. In the case of not wanting to park in the town, the situation is more delicate. In this case, regional regulations require you to spend the night in an area expressly authorized for this purpose since the Tena Valley is a protected environmental space. What do we get clear? In a municipality, a person can spend the night without any problem in their car or caravan as long as the vehicle is parked correctly and they do not take belongings and objects outside (from chairs to awnings). In that case, the driver is considered to be camping and this can only be done in an area authorized for this. Therefore, living inside a van and making life in it is not illegal as long as no noise or fluids are generated that are emitted to the outside. … Read more

In 2011 Japan closed the largest nuclear power plant on the planet. Now he has decided to reopen it in the midst of the energy debate

by

The nuclear debate, which Japan thought closed, returns to the scene. The authorization of the governor of Niigata to reactivate Kashiwazaki-Kariwa, the largest atomic plant in the world, has set off alarms: citizen distrust, the shadow of Fukushima and doubts about whether TEPCO is the right company to lead the country’s new energy stage are emerging. A new nuclear revival? The Kashiwazaki-Kariwa plant, managed by Tokyo Electric Power Company (TEPCO), has not produced a single kilowatt since 2012. The closure was a direct consequence of the 2011 tsunami and the three meltdowns from Fukushima Daiichia blow that left reactors with similar designs under suspicion. That technical coincidence was enough to keep its seven reactors on hold for more than ten years, despite the fact that the plant was essential for the electricity supply of northeastern Japan. According to Japan TimesHideyo Hanazumi has authorized a step-by-step reactivation that will start with reactor 6—one of the most recent and powerful—and that, later, will also include reactor 7. Altogether, the complex exceeds 8,000 MW of capacity, a figure that not only imposes: it maintains it as the largest nuclear facility on the planet. A significant change for the Japanese country. Kashiwazaki-Kariwa has gone from a technical project to a strategic move. As reported by the Financial TimesTokyo trusts that its reactivation will contribute to lowering the electricity bill and ensuring energy sources with fewer emissions, at a time complicated by the Russian invasion of Ukraine and the fall of the yen, which makes fossil fuel imports more expensive. Japan, which before Fukushima generated almost 30% of its electricity with atomic plants, fell to practically zero after the disaster. Since then 14 reactors have reopened and others await local or regulatory approvals. The government aims for nuclear energy to once again represent 20% of the mix in 2040. In addition, TEPCO would improve its annual accounts by around 100 billion yen thanks to the restart, according to Japan Forwardat a time when it continues to face enormous costs for the dismantling of Fukushima Daiichi. The reactivation process. The restart will begin with unit 6, which already has fuel loaded and will begin commercial operations before March of next year. To move forward, TEPCO must respond to the Government’s demands, which include updating all security systems and improving emergency evacuation plans. The process has not been easy. As detailed by Japan Timesthe plant passed safety reviews in 2017, but then suffered a veto from the Nuclear Regulatory Authority due to deficiencies in anti-terrorist measures, lifted in 2023. In addition, TEPCO had to incorporate biometric controls and correct security flaws after new internal incidents. Is there controversy? Yes, and a lot. According to a survey cited by the BBC50% of Niigata residents support the revival, while 47% oppose it. However, almost 70% express their concern because the person operating the plant is the same company that caused the accident. From Japan Times He adds that the rejection intensifies in some of the towns located within 30 kilometers of the plant, where the majority fear a new disaster or distrust the company. Another source of discomfort, also pointed out by this medium, is that the electricity generated is not used in Niigata, but in the Tokyo region. The political dimension is equally tense. Hanazumi, aware of the sensitivity of her decision, has announced that he will submit his continuity as governor to the vote of the prefectural assembly, the only body that can remove him. But there is something else at play. The reopening of Kashiwazaki-Kariwa is seen as a pillar to ensure the country’s energy security and avoid possible power outages in Tokyo. It would also allow reducing electricity rates that have increased notably since 2011. At the same time, Japan is not only restarting reactors: it is also is planning the construction of new plants with fourth generation reactors, which would mark a new chapter in the country’s energy policy. More than a return to the atom. The country that one day vowed not to depend on atomic energy again has ended up returning to it, driven by necessity, geopolitics and the urgency to decarbonize. It remains to be seen if this decision will also ignite the confidence of a citizenry that still carries the memory of Fukushima or if, on the contrary, the return to the atom will deepen a division that has been open for more than a decade. Although the governor’s approval is the decisive step, there are still procedures: the prefectural assembly must debate and vote on the decision in December, and the Japanese nuclear regulator must complete the formal procedures for reactivation.

A new mathematical proof settles the debate over whether the universe is a simulation

by

What if everything we see, feel and experience is not real? It is one of the most fascinating ideas in science fiction and modern philosophy, in which it is proposed that everything around us it’s a real simulation of computer of some higher civilizationas if we were literally sims. And such is its magnitude, that science has had to come out to deny this idea. The problem. The ‘simulation hypothesis’ has gone beyond being a simple movie premise to a serious debate in technology circles and physical. The argument is usually statistical: if a civilization can create one simulation of reality, it will probably create many. These simulations could in turn generate their own and in this infinite ‘stack’ of realities, the odds that our universe be original, they are almost non-existent. And although this has been a very restrained topic among philosophers, science has also wanted to fully enter into research to respond to a problem within fundamental physics and pure mathematics. And the answer is quite clear: we are not in a simulation. The study. An international team of physicists, including Dr. Mir Faizal of the University of British Columbia (UBC) and renowned physicist Dr. Lawrence M. Krauss, has mathematically proven that the universe cannot be a computer simulation. His findings, published in it Journal of Holography Applications in Physicsnot only disprove the idea, but reveal something much deeper about the nature of reality: the universe is based on a type of “understanding” that exists beyond the reach of any algorithm. The reality. To understand this test, we must first understand what ‘reality’ is. Modern physics no longer sees the universe as tangible ‘matter’ moving in empty space, but thanks to Einstein space and time merged to now demonstrate that the microscopic world is probabilistic. The most widely accepted theory today focuses on quantum gravity, which suggests that space and time are fundamental. They are “emergent”: they spring from something deeper, something more like pure information. In this way, physicists assume that a “Theory of Everything“(ToE) that unifies gravity and quantum physics would, in essence, be a large axiomatic system: a set of meaningful rules and algorithmic calculations from which the entire universe, including spacetime itself, could be “computed” and generated. Incompleteness Theorems. In 1931, logician Kurt Gödel demonstrated something that blew up the foundations of mathematics: any formal system (such as a computer program or a set of physical laws) that is complex enough to include basic arithmetic will be incomplete or inconsistent. By ‘incomplete’ we mean that there will be true statements within the systems themselves that will never be able to be demonstrated following their own rules. It’s like the famous paradox that says “this statement is true, but it cannot be proven.” Faizal’s team argues that any purely algorithmic ToE would suffer from this limitation. There would always be “Gödelian truths” about the physics of the universe (perhaps about specific microstates of black holes or the nature of the singularity) that such a computational system could not test. Two layers. If the algorithmic universe is “incomplete”, how does our reality seem to work? Researchers propose that reality is not only the algorithm. This is what allows the universe to “know” that these Gödel truths are true, even though the algorithm alone cannot prove them. It is a fundamental layer of reality that transcends simple computing. The final test. With all the pieces on the table, the refutation of the simulation hypothesis becomes clear and elegant. The first of all is that every simulation is logarithmic, that is, a computer executes a problem following very specific rules that leave no room for doubt. In this way, we come face to face with our theories that are not ‘perfect’ in their demonstrations. But they don’t stop there, since scientists have pointed out that an algorithm can only simulate the algorithmic part, meaning that a computer could only, in the best of cases, emulate the computational and incomplete part of our universe. And the most important thing without a doubt is that our universe is more than an algorithm, since as Gödel’s theorems demonstrate, complete physical reality must include a non-algorithmic layer to be consistent and complete.

the debate on gasoline additives returns with force

by

“That is the big lie. We buy the additive that Exolum recommends. But it is not worth anything, nor is it worth anything. We put the additive because people think that the additive is good” We don’t say that the additive is “worthless” at all. Of course, neither does “the best mechanic in Spain” say it, who firmly believes that gasoline low cost it is of worse quality. The person who speaks about the convenience or not of the additive is José Rodríguez de Arellano, “the king of cheap gasoline”they assure in The Country. In the Spanish newspaper they have interviewed Rodríguez de Arellano, CEO of Plenergya gas station company with 370 points of sale throughout Spain and which already sells about 1,700 million liters of fuel. Obviously, Rodríguez de Arelllano’s words hit home. Asked about the convenience of using additives to improve the useful life of the engine, the company’s CEO is very clear: “if it was worth something, the leaders would have already said so.” What do we know about additives Whether or not it is convenient to use additives for the car or refuel at a gas station that is supposed to be of “better quality” has some truth and a lot of hope. Because, really, if the fuel we refuel has the minimum quality standards that fuel in our country must meet, there should be no problem. What must be clear is that the gasoline we put in our tank at Plenergy or Ballenoil it is the same as if we do it at Repsol or BP. At least, it almost entirely is. As if it were a stew where everything comes from the same pot but then each cook ends up giving it their personal touch. The origin of all the fuel consumed in Spain is in Exolum, former CHL. The fuel comes to Exolum from the refineries that BP, Repsol or moeve They are spread throughout Spain. There it is verified that the fuel has the minimum quality for sale in our country and is distributed to the different companies. It is in this distribution where the differences begin. Exolum itself already sells fuel with and without additives. It is known as HQ300 and makes the product more expensive. “ANDIt’s the big lie. “We buy the additive that Exolum recommends.”. In his interview with The Countrythe CEO of Plenergy confirmed that they use this additive fuel and that, however, for him it made no sense and that it was a pure marketing exercise. And he continued: “The additive is not important for the engine. What happens is that we are in a dynamic in which everyone talks about the additive. If it was of any use, the leaders would have already said so. They would have done an independent study to demonstrate that their additive allows the car to go x kilometers longer. It is the same fantasy that still exists in the country, understanding that the fuel is different, but comes out of the same tank.” And this is where much of the secret lies. Once Exolum delivers its fuel with or without additive, it is the companies themselves that provide that chef’s touch that we were talking about. The most renowned firms (and cost for the customer) use their own additives that, they claim, improve the useful life of the engine or make the car travel more kilometers with the same amount of fuel. That is, consume less. However, there are so many conditions When it comes to demonstrating that this really influences it, it is not entirely clear that there is a real benefit. In fact, if you go to one of the websites where the operation of the additives is explained, they will always be accompanied by a small legal text at the bottom. Regarding longer engine life and better efficiency (BP assures that cars that use its fuels can travel 840 kilometers longer for every 13,000 kilometers traveled) On the BP website it reads the following: *Benefits are achieved over time and may vary depending on how and what vehicle you drive. **Claim based on continuous use over 13,000 km. Compared to basic fuels (fuels that only meet the minimum requirements established in Royal Decree 61/2006 of January 31). Benefits may vary depending on vehicle, driving style, road conditions and other factors. The problem is that it is almost impossible to carry out studies that can be translated into practice. Fuel consumption is closely linked to driving style but also to much simpler causes such as keep the tires at the correct pressure or simply perform proper maintenance of the vehicle, which can have much more impact on fuel consumption and avoiding possible breakdowns than on the use of one fuel or another. Everything indicates that so many kilometers would have to be traveled with so many different engines and for so long in laboratory conditions that the cost would be too high. That is why Rodríguez de Arellano assures that “the leaders” have not presented any independent study that validates the use of additives to improve the fuel that arrives from Exolum. This last perspective was the one validated by Carles Fité, professor of Chemical Engineering, and Rodrigo Soto, reading professor of Chemical Engineering, to The Confidential. Both experts pointed out that all the gasolines they had on display had the same base and that there were no substantial differences between them that could confirm that these supposed benefits exist.

The reactive the great debate on universal basic income. And the question is whether it is feasible to create it: Crossover 1×23

by

One hears about Universal basic rent and inevitably thinks that It’s money that gives you free. The idea goes far beyond that, but one thing is true: with the rise of AI and the potential revolution of robotics, the debate about this option is more rising than ever. And precisely this 1×23 crossover is dedicated to talking about universal basic income, its origins and what it means. And to do so are Jaume Lahoz and Carlos Santa Engracia, presenters of Crossover, and a server, Javier Pastor, to dissect the theme. The truth is that we are increasingly facing a future in which AI and automation can help Create ultraproductive companies. In that scenario it is likely that the impact for employment and society will be enormous, and that is where a Universal basic rent You can raise a solution to that “mass and forced unemployment.” In the episode we talk in addition to the Pilot experiments That there has been in various countries, and also how Sam Altman, CEO of OpenAI, is especially interested in this area through its controversial Worldcoin project. Like everything, in the idea that projects universal basic income there are clear advantages and of course also risks. Will we become a society Like the one painted ‘wall-e’? ¿We will all gorditos And without moving from a chair that levita and takes us everywhere? Phew. On YouTube | Crossover

A patch updates the debate on difficult games

by

The high difficulty of ‘Hollow Knight: Silksong‘One of the issues that to those of the players has once again put in the arena: The very high difficulty. Is it necessary? Should titles such as SOULIKE or this same ‘Silksong’ your demands to be more accessible, or if it is a design decision, the right thing is that they remain as its creators have decided? In any case, Team Cherry has heard the complaints of the players and will be predicted to the desperate difficulty of its successful Metroidvania. Difficult that you spend. Many players, even experienced adventurers who were already tanned from the original and quite demanding ‘Hollow Knight’ have noticed that ‘Silksong‘proposes a considerably higher challenge: from fighting (already overcome the first Boss final It is a challenge that has given to speak) to the platform mechanics, through more lethal enemies, a more complex combat system and, above all, a structure that does not forgive failures and that can force the painful player to repeat paths that he has already traveled. But why. It is no longer that enemies do more damage with their blows or have more resistance to the player’s envies. It is rather that ‘Silksong’ demands to be very cautious since the same start of the game, where they are already on the advanced mechanical table of the genre Metroidvaniaand above all, that there is a combat design that hinders things. As Polygon saidfor example, the protagonist hits down diagonally, which makes it more difficult to control her blows in this direction. It is not a matter of skill: we have to relear mechanics that we take for grasses in the genre. Team Cherry recognizes it. However, the creators of the game recognize that The game could be more balancedespecially at the first levels. Therefore Team Cherry announces that will launch an update of the game that will arrive in the mid -week and that will adjust the difficulty of the start. Of course, the game is not going to become a walk, something that would make him lose his personality, but the Australians pretend that no one despairs in those first measures. The players will see the rewards of rosaries and reduced the damage inflicted by some enemies. Difficulty and damage to the Moorwing and Sister Splinter (a key enemy, since it provides the ability to jump bouncing on the wall, essential to advance) will also be moderated. PC users already have the patch available in Steam and GOG. If you like to suffer. Do not worry if you have masochistic trends: Silksong includes a secret mode, ‘Steel of steel‘, which is played to the highest level of difficulty and with permanent death. This mode is unlocked at the end of the game, but the wasp community has discovered a combination of buttons (legendary and easy to guess, everything must be said) that allows you to activate it from the beginning, offering an extreme challenge for the most skilled. Neither patch nor parcha. The eternal debate. He debate about high difficulty in video games It is recurring: on the one hand, there are those who defend the unique difficulty that the creator sets so that the game is a challenge, looking for the satisfaction that generates overcoming difficult obstacles. On the other hand, there are accessibility apologettes that demand adjustable modes for all audiences to enjoy the game, regardless of their level of skill. This debate also involves how difficulty peaks affect the experience: some players consider them a bad design that frustrates, while others look for these peaks as treasures that create memorable challenges. In Xataka | This game dared to go on sale the same day as ‘Silksong’. All he got was attracting 12 players in his debut

The solar panels 35 years ago are lasting so much that they have reopened the debate on the quality of the current

by

The solar panel manufacturers They usually offer performance guarantees of about 20-25 years, a point from which the irremediable degradation of materials significantly reduces their ability to produce energy. Or that’s what they have done to believe. Short. A new analysis of solar panels installed in Switzerland between 1987 and 1993 reveals that most follow 80% of their initial nominal power. The study is based on six photovoltaic systems in operation for more than 30 years in all types of altitudes. Research, published in the EES Solar MagazineNot only confirms that solar panels can last a lot more than 25 years, but do so with such a low degradation that invites you to review priorities: are we balancing well efficiency, cost and materials? A degradation much lower than the typical. The researchers studied thoroughly from solar panels in low altitude roofs to facilities in alpine areas. On average, the panels lost only 0.24% of power per year. It is a value significantly lower than the usual range of the crystalline silicon: 0.5 to 0.6% per year, depending on the weather. In other words, these 35 -year modules degrade much more slowly of what the industry today assumes as usual. The secret is not the climate, but the materials. The weather can make a difference. In colder alpine environments, despite receiving more radiation, the degradation of the panels is slower due to the least thermal stress. At low altitude, where the surface of the panels can reach 80 ° C, Metallic contacts can run and lose conductivity for the degradation of the encapsulant. However, the secret of these panels is their solid construction. The modules analyzed are from the family of AM55 arc models and Siemens SM55, which stand out for the quality of their materials: thicker frontal glass, high quality encapsulants, very resistant rear sheets, robust aluminum frames and crystalline silicon cells somewhat thicker than the current ones. The moral of the study. Today’s photovoltaic industry has no point of comparison with that of the early 90s. The panels are much cheaper and achieve greater efficiencies. But in return, they use thinner silicon wafers, thinner glass and lighter designs. The conclusion of the study is not that before better panels, but that manufacturing materials have a great influence on long -term performance. Although they cannot compete with the current price, betting on robust and quality materials can make the useful life of a solar panel exceed 50 years in temperate climates.

There is an open debate about sports motorcycles and the DGT has not been left out

by

The motorcycles have become the last refuge of the maximum sportiness expression that we can see in the streets. Faced with increasingly heavy cars and monitored by the European Union, motorcycles continue to maintain low weight maximum (relatively), stratospheric acceleration and tip speeds that take away the hypo. And, of course, there is an open debate. “With head”. The statement is the renowned Italian pilot and journalist Nico Cereghini who pointed in the Italian media Moto.it That “as bikers, if we only thought with head, today we would all be with 20 or 30 hp of maximum power under the back.” Then he points out: “But every passion has little rational, as is known. Emotions are sought, they are chosen with the stomach and with the heart.” In his column, Cereghini says that it will not be the users who opt for rationality, so he wonders if manufacturers should not “take care of establishing limits, before the legislator does it in their place.” “They are very busy packaging dreams, deceiving the consumer that they can run very fast, it is not known where or when.” A debate that is not new. Cereghini’s reflection is striking for his weight in the public debate of motorcycling but is not new. In the 90ssports motorcycles were completely dismembered with maximum infarction speeds that exceeded 300 km/h. The most striking were Japanese motorcycles, excessive powers and an electronics that almost shone due to its absence. Aware that this could be a problem and that they began to enter a crazy race to reach 400 km/h on a street motorcycle, someone decided to put some sanity and A gentlemen’s pact was signed To limit power … at 299 km/h. The DGT has its opinion. And, of course, it is not very close to that of speed fans. Pere Navarro, director of the DGT, I already pointed out last year that “a 200 -horsepower motorcycle with 200 kilos is Made for the circuit and on the road it has a special danger, everyone has to be aware of it. “ From there, the bulles shot up. As usual with the DGT, social networks were filled with comments ensuring that traffic was going to ban this type of motorcycles but as they remembered in Motorpasion motorcyclethere was nothing on the table and, in fact, they cannot make this decision for themselves. Has any measure been taken? These motorcycles with a supercar power weight have always been in the spotlight but almost surprising that, seeing the efforts that have been taken by self -limiting cars in Europe with a Arsenal of ADAS systemsthe focus on this type of machines has been minimal. Already in 2008Pere Navarro made statements in which he was favorable to apply a limitation to 100 hp for motorcycles. This proposal was studied in the European Parliament at the request of France, which already applied the measure, but did not go ahead. The French exception. In France, Motorcycles have been limited to 100 hp between 1985 and 2016. In the 80s it was considered that this 100 hp barrier should not be overcome, establishing a red line that they considered too dangerous. Then the market was saturated with motorcycles between 50 and 70 hp and safety among motorists was minimal. In 1995, Europe decides that countries that want to take advantage of this limitation are in their right to do so but only France follows this path. After many debates and resources, the European Union established in 2012 a New regulation for motorcycles and eliminates the French exception that rises in 2016 by European mandate. An anachronistic situation. The world of yield represents something almost exceptional right now. We could say that it almost seems anachronistic that a motorist can reach infarction speeds when damage is usually much more serious in a motorcycle accident than in the car for obvious issues. Of course, the European Union has done everything possible to limit the latter. But it is not only a matter of regulations. Among cars manufacturers too They begin to be common Limitations at increasingly low speed. Good for technical reasons (electric car) or claiming security reasons (like Volvo) But it is evident that speed begins to see with bad eyes. With such bad eyes that even in Germany There are more and more favorable voices to the limitation of speed in the mythical autobahn.

How much meat is too much meat? This is how the debate about meat is changing

by

For years they have told us that meat is a source of protein, iron and tradition. In many cultures, he is the queen of the dish. But today, between the growing public health problems and environmental urgencies, the question is no longer whether we must eat meat but how much meat is too much meat. The answer is not as simple as it seems. The consumption map. The meat is still the protagonist on our tables, but its impact is triggered. In recent decades, its production and consumption have grown accelerated: Statista and Our World in Data They estimate that we could reach 570 million tons per year in 2030, an increase linked to global population and economic growth. Countries such as Spain, France, the United States or Japan, consumption levels They exceed 100 kg per person a year. However, according to A study published in Nature Foodmore than 255 grams of white meat per week already calls into question the planet’s capacity to regenerate the resources that this industry requires. Red meat directly is outside any diet compatible with sustainability, according to Caroline Gebara, main author of the study. Less is more. From medicine and nutritional science, the message is increasingly clear: reduce the consumption of meat – especially red and processed – is beneficial. According to Healthline and studies collected at MIT Press Readerits intake is related to a higher risk of cardiovascular diseases, colorectal cancer and general mortality. In the Course of Integrative Oncology of the University of Santiago de Compostela, the Nutrition Professor Lourdes Vázquez explained for the voice of Galicia that the approach must be integral: “The more foods of plant origin, the better. We do not want to demonize, but the diet set.” From Brussels, the European Union has put figures to the Council: Limit red meat to 300-500 g per week, and the prosecuted to no more than 30-150 g, depending on the country. In the Spanish case, food guides recommend from 0 to 3 weekly portions, with preference for white meats such as chicken or rabbit. What evolution says. We know that humans have eat meat for thousands of years. What is not so clear is when he started playing a key role in our diet. ORn study commented in The Conversationwhich analyzed nitrogen isotopes in fossil teeth of Australopithecus in South Africa, suggests that these predecessors ate mostly plants. However, a opposite hypothesis, cited here in Xatakastates that during much of the Paleolithic we were hypercarnivores, hunting large mammals and developing physiological adaptations for frequent consumption of meat. Faced with both positions, the biologist Gidon ESHEL questions the usefulness of appealing to evolution to justify modern habits. In your essay for Mit Press Reader He has affirmed: “Evolution does not prescribe our current diets. If more than two out of ten plant foods can nutritionally replace meat, then meat is not indispensable.” Leave it at all? It is not necessarily about becoming vegetarians or vegans overnight. There are gradual alternatives, such as Pescetarianismbased on vegetables and fish, or the flexitarianisma more flexible option that does not eliminate meat, but yes It reduces its frequency and quantity, promoting the consumption of legumes, vegetables and integral cereals. They are only different approaches that show as a bridge to adapt to different personal, cultural or economic contexts. A more conscious diet. So how much meat is too much meat? The answer is not an exact number, but an invitation to moderation. Eating less meat, better quality, accompanied by more vegetables, fruits and legumes not only improves individual health: it is a specific measure to preserve the planet. Reducing meat consumption does not imply giving up the pleasure of eating. It means adopting a way of feeding more conscious, informed and sustainable. As concluded The study published in Nature Foodthere are many dietary combinations that allow to maintain health and take care of the environment. It is not about prohibiting, but about transforming.

Walking is an exercise that not only has the advantage of helping us maintain good health, it is also affordable for people with difficulties to exercise in other ways due to circumstances such as age or rhythm. However An old debate persistsSI for extract the benefits of this exercise We can go with a relaxed step or if on the contrary a prescription rhythm is essential. If there are no reasons such as injuries that can be aggravated with sports, physical activity, even in “small doses”, it will always be better than inactivity. That is why the debate about the ideal of walking slowly suits us is easy to settle: walking slowly is better than not walking. Of course, experts tend to agree that, if we have the possibility, better to accelerate the step. Walking can help our health in different ways. Our heart health is, surely, the one that can be appreciated most to wear comfortable footwear and go for a walk, but it is not the only one. Walk has been related to a lower impact of diseases such as diabetes but can also have psychological benefits such as stress reduction or help Improve concentrationespecially when we walk through natural environments. But then what about the Benefits of walking quickly? Again, cardiovascular health is in the center of the debate. A study Recent in highlighting this is the one published in 2024 in the magazine Atherosisclerosis. The study, which had almost 20,000 participants, analyzed their mortality in a period of 9.4 years. The team responsible for the analysis detected an inverse relationship between the rhythm with which they used to walk and the risk of death and suffering from cardiovascular diseases. Studies that relate the rhythm of our gait with the benefits that walk gives our health They are diverse. Some also cover the relationship between speed and cognitive deterioration. Some examples are found in The review published in 2016 In the magazine Ageing Research Reviews. The team responsible for the analysis found a relationship between the speed of the passage when walking and the cognitive deteriorationalthough it was not conclusive about the existence of a direct causal relationship since it could also be cognitive deterioration that makes us walk more slowly. Lose weight Weight is an important risk factor in many diseases. That is why, although thinning does not have to imply that we will be healthier, it can be useful to reduce this risk or as a simple motivation towards healthier habits. Among them, exercise. If our goal is to lose weight, accelerate the step It can also be helpful. Of course, the context can be important, as a group of researchers recently discovered. In Your studypublished in 2024 in the magazine Sports Science & Medicine, They detected that Genetics could be decisive when reducing our weight through this type of exercise. Walking is an affordable and healthy exercise, but science finds more and more evidence that it is best to accelerate the step if we want to make the most of the benefits of our walks. Walking, even at a leisurely rhythm, can help our health, but can also help us take the habit necessary to direct us, little by little, towards a more active life. Step by step.
