"Our smartphones enable-and encourage-constant connection to information, entertainment, and each other. They put the world at our fingertips, and rarely leave our sides. Although these devices have immense potential to improve welfare, their persistent presence may come at a cognitive cost. In this research, we test the "brain drain" hypothesis that the mere presence of one's own smartphone may occupy limited-capacity cognitive resources, thereby leaving fewer resources available for other tasks and undercutting cognitive performance. Results from two experiments indicate that even when people are successful at maintaining sustained attention-as when avoiding the temptation to check their phones-the mere presence of these devices reduces available cognitive capacity. Moreover, these cognitive costs are highest for those highest in smartphone dependence. We conclude by discussing the practical implications of this smartphone-induced brain drain for consumer decision-making and consumer welfare."

"Con el paso del tiempo, el hombre primitivo se ha ido transformando en el moderno homo tecnologicus. El homo tecnologicus es un ser humano muy sofisticado que desarrolla sus actividades en una sociedad altamente tecnológica e industrializada. El homo tecnologicus se transporta a su lugar de trabajo en un automóvil con aire acondicionado y GPS, trabaja en un edificio que cuenta con las últimas tecnologías domóticas, ascensores inteligentes y máquinas dispensadoras de café, dispone de un ordenador con conexión a Internet y correo electrónico y mantiene conferencias virtuales con compañeros de trabajo, familiares y amigos en otros países. Pero sobre todo, el homo tecnologicus es un homo sapiens con un elevadísimo consumo energético. El consumo energético medio del homo tecnologicus en cualquier país altamente industrializado es equivalente al consumo de doce mil vatios de potencia durante 24 horas al día durante los 365 días del año. Es decir, consume el equivalente a seis secadores de pelo o 120 bombillas incandescentes encendidos durante todo el año. Un hombre primitivo de las cavernas, perteneciente a la sociedad cazadora-recolectora, presentaba un consumo energético medio equivalente a la potencia de una bombilla incandescente de 100 vatios encendida las 24 horas del día durante un año. No es difícil deducir que un homo tecnologicus consume 120 veces la energía de su lejano predecesor, el homo sapiens. Un homo tecnologicus equivale, energéticamente, a 120 hombres primitivos. 120 hombres primitivos trabajando incasablemente para satisfacer las necesidades energéticas de un homo sapiens del siglo XXI."

"France plans to outlaw the destruction of unsold consumer products, a practice that currently results in the disposal of new goods worth 800 million euros, or more than $900 million, in the country each year. By 2023, manufacturers and retailers will have to donate, reuse or recycle the goods, Prime Minister Édouard Philippe said on Tuesday of the measure, which the government billed as the first of its kind. "It is waste that defies reason," Mr. Philippe said at a discount store in Paris, according to Agence France-Presse, and he called the practice "scandalous." Under a new measure that will be part of a bill set to be debated by the government in July, destroying unsold goods could result in financial penalties or prison time. The practice - widespread across the retail and consumer industry as a way to free up warehouse space or prevent unwanted items from being sold at a significant discount - has received bad press in France recently. ..."

"The Kaua Moho was the last species of it's entire genus and it was the last genus in it's family. This male was not just the last of his kind, he was the last being on his entire branch of the evolutionary tree, there was nothing left on the planet that was even close to being like him. That kind of loneliness is unimaginable. No other avian family has had every single species within it go completely extinct in modern times. Different species of Moho lived on each island of Hawaii and their evolutionary cousins the kioea birds lived alongside them, but starting in 1800 (about the time Europeans started arriving to the islands in significant numbers and also about the time the native human population of Hawaii also got decimated by diseases) one by one they died out due to the introduction of foreign avian diseases and parasites, habitat loss, and hunting for their plumage. 2 hurricanes within 10 years of each other finished them off. They are all gone and that song or any song like it will never be heard again save for in recordings. The hurricanes dealt the final blow, but 95% of it was humanity's fault. This has become common in Hawaii due to having so many species that only exist there. A LOT of those species are gone now because the arrival of Europeans brought disease, invasive species, and people straight up killed them or destroyed their habitats. It is a similar situation on every isolated island or area in the world as humans have expanded and explored every nook and cranny on the planet, no matter how hard it is to get to or how little business we have there we feel the need to interfere in even the most delicate and tiny ecosystem. Even the large, continent sized ecosystems are suffering. It doesn't matter if there are millions or even billions of an animal or plant, we will find some way to kill them all. It is only in the last few decades that serious steps have finally been taken to preserve the few areas on this world that we have not destroyed, but

"Burden of Poverty Lacking money or time can lead one to make poorer decisions, possibly because poverty imposes a cognitive load that saps attention and reduces effort. Mani et al. (p. 976; see the Perspective by Vohs) gathered evidence from shoppers in a New Jersey mall and from farmers in Tamil Nadu, India. They found that considering a projected financial decision, such as how to pay for a car repair, affects people's performance on unrelated spatial and reasoning tasks. Lower-income individuals performed poorly if the repairs were expensive but did fine if the cost was low, whereas higher-income individuals performed well in both conditions, as if the projected financial burden imposed no cognitive pressure. Similarly, the sugarcane farmers from Tamil Nadu performed these tasks better after harvest than before. Abstract The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy."

"A lo largo de los tres siglos que necesitó el capitalismo para consolidarse como sistema hegemónico -en el sentido gramsciano-, se fue imponiendo la ley de la oferta y la demanda, en detrimento de los gremios medievales, que durante siglos impidieron la competencia. Y cambió el significado social del dinero, que ganó un protagonismo central al tiempo que, progresivamente, se justificó el cobro de interés, que había sido condenado durante siglos. Los sistemas políticos europeos se tomaron más en serio la libertad que la igualdad y la fraternidad, de la tríada de valores de 1789 (liberté, égalité, fraternité), y la propiedad privada se erigió en el valor supremo de las constituciones, mientras se expandían por Europa las ideas de Adam Smith y John Locke. El Estado, en su concepción moderna, apareció como garante último de la reproducción del capital como eje ordenador de la sociedad; aunque, eso sí, no exento de tensiones y contradicciones, pues los estados europeos debían -y deben- sostener simultáneamente dos instituciones contradictorias: la acumulación creciente de la riqueza económica y el mantenimiento, al menos formal, de la democracia política. El engranaje capitalista estaba en marcha, pero su despegue sólo fue posible con la Revolución Industrial, que comenzó en la Inglaterra del siglo XVIII y se profundizó y expandió el siglo siguiente, sobre todo, desde el momento en que comenzaron a utilizarse los combustibles fósiles (Fernández Durán y González Reyes, 2014). La ingente cantidad de energía que éstos proveían, junto al desarrollo tecnológico, permitió el abaratamiento de los procesos productivos y la expansión de la industria y, con ello, del consumo. Entre los siglos XVIII y XIX, Europa y Estados Unidos asistieron a un espectacular aumento de la producción: para el historiador Neil McKendrick, fue la primera revolución consumista de la historia. La consecuencia inmediata fue una profundización y aceleración

""El colapso ya está sucediendo, aunque no seamos muy conscientes de ello" Enric Llopis Rebelión La función de la energía en el devenir histórico y la noción de colapso son dos de los argumentos centrales del libro "En la espiral de la energía", de Ramón Fernández Durán y Luis González Reyes. Coeditado por Ecologistas en Acción y Baladre, el texto de cerca de mil páginas y dos volúmenes constituye un trabajo enciclopédico que comienza en las "sociedades opulentas" del Paleolítico y termina en el colapso del sistema urbano agro-industrial civilizatorio. El colapso, noción muy vinculada a la idea de complejidad, "ya está sucediendo aunque no seamos muy conscientes de ello; desde el punto de vista de nuestras vidas, el colapso será relativamente lento, aunque en términos históricos sea muy rápido", afirma Luis González Reyes. El autor, miembro de Ecologistas en Acción, también forma parte de Garúa, cooperativa en la que trabaja en cuestiones de formación, intervención social e investigación. En FUHEM colabora para la inclusión de los temas ecosociales en el proceso de aprendizaje de los alumnos de tres colegios. González Reyes es además autor de "Sostenibilidad ambiental: un bien público global" (Akal) y "La política ambiental de la Unión Europea" (Ecologistas en Acción). Ha colaborado en "¿Qué hacemos frente a la crisis ecológica?" (Akal) con Jorge Riechmann, Yayo Herrero y Carmen Madorrán. -¿Qué es el Antropoceno? ¿Cuándo surge el concepto y qué quiere significarse con el mismo? El Holoceno, la etapa histórica que coincide con el inicio de la agricultura (los últimos 12.000 años), ha tocado a su fin, ya hay una nueva era geológica: el Antropoceno. El término Antropoceno fue acuñado por Crutzen en 2000. Además, la Sociedad Geológica de Londres así ha definido a esta etapa de la historia terrícola. Una sola especie, la especie humana, o mejor dicho, una élite de ella (en ese sentid

"The Fairphone is a modular handset designed with repairability and ethical sourcing of its materials as headline features. It sold 60,000 units. Amazingly, for what sounds like a nerd-phone, almost half of those buyers had never owned a smartphone before. Now the Fairphone 2 is launching, and with a totally-new, in-house design. The new phone is even easier to repair, and because it was wholly designed by the FairPhone team, its supply chain is even more responsible than ever. The Fairphone is thicker than the latest iPhone or Samsung flagship, but that's the point. Instead of packing everything into a tiny case and keeping it there with glue, the Fairphone is designed to be taken apart. The lightweight magnesium frame supports modules that can be easily replaced by the user. "We have designed it with an aim to last three to five years, looking at making it robust and modular-for repairability," says Fairphone's chief communications officer, Tessa Wernink. "Obviously how long it lasts depends quite heavily on the user, so what we as a company are doing is offering an ecosystem around the phone that supports long-lasting use, first-hand or second-hand." Inside the case (itself one of several options) you'll find the core unit, containing all the chips and radios; a replaceable battery pack; a display that can be snapped off and replaced without any tools (not even a screwdriver); a receiver unit, which contains the front camera, sensors; the headset connector and microphones; a speaker/vibrator unit; and a camera module. These modules are designed to balance manufacturing complexity with repairability. For instance, the display comes as a standalone unit, but less-vulnerable components are bundled into one module. The camera, which people are most likely to upgrade as better versions become available, is also housed in its own module. That way you don't need to toss out your whole phone just to get a better camera. "In fact, the motto from the maker mo

"Our new blog is designed to radically reduce the energy use associated with accessing our content. Low-tech Magazine was born in 2007 and has seen minimal changes ever since. Because a website redesign was long overdue - and because we try to practice what we preach - we decided to build a low-tech, self-hosted, and solar-powered version of Low-tech Magazine. The new blog is designed to radically reduce the energy use associated with accessing our content. Why a Low-tech Website? We were told that the Internet would "dematerialise" society and decrease energy use. Contrary to this projection, it has become a large and rapidly growing consumer of energy itself. In order to offset the negative consequences associated with high energy consumption, renewable energy has been proposed as a means to lower emissions from powering data centers. For example, Greenpeace's yearly ClickClean report ranks major Internet companies based on their use of renewable power sources."

"The cryptocurrency uses as much CO2 a year as 1m transatlantic flights. We need to take it seriously as a climate Bitcoin's electricity usage is enormous. In November, the power consumed by the entire bitcoin network was estimated to be higher than that of the Republic of Ireland. Since then, its demands have only grown. It's now on pace to use just over 42TWh of electricity in a year, placing it ahead of New Zealand and Hungary and just behind Peru, according to estimates from Digiconomist. That's commensurate with CO2 emissions of 20 megatonnes - or roughly 1m transatlantic flights."

"Last year I went to West Kalimantan in Borneo to see for myself the effects of the runaway growth of the palm oil industry. I came home firm in the belief that Iceland would not continue using palm oil until companies delivered on their zero deforestation commitments. This is because palm oil has had devastating consequences for local communities, who are being displaced, and on endangered species like the orangutan (our closest relative in the wild), which are being driven close to extinction. Palm oil has many benefits, chiefly that its yields are better than the alternatives. But it is grown almost exclusively in areas of tropical rainforest, which are the 'crown jewels' of our planet's biodiversity. With 146 football pitches of rainforest being lost every hour in Indonesia alone, the urgency of the crisis cannot be overstated. And global demand is set to double by 2050. At Iceland the 1,000 tonnes of palm oil we used annually pale into insignificance compared to many of our competitors. As such a tiny player we took the decision that the only way we could create meaningful change was to shout very loudly from outside the established palm oil industry. So we decided simply to stop using palm oil until the industry cleaned up its act. It was our own decision to give consumers a choice where previously there was none. We never called for a wider industry ban, and accept entirely that a wholesale boycott of palm oil is not the right long term solution. ..."

"This book YOUNG & CREATIVE - Digital Technologies Empowering Children in Everyday Life aims to catch different examples where children and youth have been active and creative by their own initiative, driven by intrinsic motivation, personal interests and peer relations. We want to show the opportunities of digital technologies for creative processes of children and young people. The access to digital technology and its growing convergence has allowed young people to experiment active roles as cultural producers. Participation becomes a keyword when "consumers take media into their own hands". Digital technologies offer the potential of different forms of participatory media culture, and finally creative practices. YOUNG and CREATIVE is a mix of research articles, interviews and case studies. The target audience of this book is students, professionals and researchers working in the field of education, communication, children and youth studies, new literacy studies and media and information literacy."

"Las necesidades humanas fundamentales o básicas son las mismas en todas las culturas y en todos los períodos históricos. Lo que cambia a través del tiempo y de las culturas es la manera o los medios utilizados para la satisfacción de las necesidades. En ese sentido, cada sistema económico, social y político adopta diferentes estilos para la satisfacción de las mismas necesidades humanas fundamentales. En cada sistema, éstas se satisfacen (o no) a través de la generación (o no generación) de diferentes tipos de satisfactores. Uno de los aspectos que define una cultura es precisamente la elección de su satisfactores. A continuación, os proponemos una serie de actividades diseñadas por Marta González Reyes a realizar en el aula para favorecer la cooperación y la reflexión conjunta entre los alumnos y alumnas entorno al tema de las necesidades humanas y los satisfactores. Estas actividades parten de una reflexión realizada en Consume hasta morir, que se puede encontrar en este enlace: http://www.letra.org/spip/spip.php?article1928."
