"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."

"Imagine you could use any kind of small head difference in a river or canal. The power those drops contain might surprise you. We created a technology that can make use of all these small waterfalls or rapids in a way that's safe for the environment. Gone are the days that communities had to choose between having power or fish to eat. Our robust and fish friendly vortex turbiness will generate energy 24/7 at an incredibly low cost of energy. That way you can have a project with high return on investment that improves the world just that little bit. Now, if you look at a river or canal, you'll notice that it's full of these small cascades, that's how nature builds rivers. We have created a distributed turbine system that can combines a large amount of turbines into one big virtual hydropower powerplant. These virtual hydropower plants can be as large as 10MW in power output. That's the power production of a small city! We can do this because our civil structures are designed to be easy to install, and the electronics and robust power take-offs are designed to keep working with minimal maintenance. The energy produced can be directly connected to your appliances or machinery, and at the same time connected to the national distribution grid, so you can inject the unused power to it, maximizing the revenue through a net billing connection."

"Carbon dioxide (CO2) is a gas essential for life- animals exhale it, plants sequester it. It exists in Earth's atmosphere in comparably small concentrations, but is vital for sustaining life. CO2 is termed a greenhouse gas (GHG) - a gas which absorbs and emits thermal radiation creating the 'greenhouse effect'. Along with other greenhouse gases, such as nitrous oxide and methane, CO2 is important in sustaining a habitable temperature for the planet: if there were absolutely no GHGs, our planet would be simply too cold. It has been estimated that without these gases, the average surface temperature of the Earth would be about -18 degrees celcius.1 Since the Industrial Revolution, however, energy-driven consumption of fossil fuels has led to a rapid increase in emissions of CO2, disrupting the global carbon cycle and leading to a planetary warming impact. As an international community, UN member parties have set a target of limiting average warming to 2 degrees celcius above pre-Industrial temperatures."

"Teaching climate science & action can seem daunting: for university-level lecturers, teaching to younger children can be quite intimidating. For primary-level teachers, the science and scope can seem too vast and fast changing to cover. For everyone, the content can be overwhelming. As adults, how do we present this topic to children: give them the information they need without crushing them? I decided to face the challenge, and over the course of one rather sleepless night, put together some materials for my 6 year-old son's class. This post summarizes and communicates that experience, in the hope that others can take ideas and inspiration, and will be encouraged to volunteer to teach about climate in primary schools. Teaching and engagement in schools is now part of all of our work, as researchers, academics, parents, activists, advocates, so I hope this idea spreads. The 4-part lesson plan worked quite well: the topics & materials held the children's attention, gave them varied aspects to think about and interact with, and they seemed to come away with deeper understanding. The whole thing took roughly 1 hour. This is doable!"

"El consumo de los hogares acomodados en todo el mundo es, con mucho, el determinante y el acelerador más fuerte del aumento de los impactos ambientales y sociales mundiales. Thomas Wiedmann, Manfred Lenzen, Lorenz T. Keyßer & Julia K. Steinberger Nature Communications volumen 11, número de artículo: 3107 (2020) Citar este artículo Resumen Durante más de medio siglo, el crecimiento mundial de la riqueza ha aumentado continuamente el uso de recursos y las emisiones contaminantes mucho más rápidamente que éstas se han reducido gracias a una mejor tecnología. Los ciudadanos ricos del mundo son responsables de la mayoría de los impactos ambientales y son fundamentales para cualquier perspectiva futura de volver a condiciones ambientales más seguras. Resumimos las pruebas y presentamos posibles enfoques de solución. Cualquier transición hacia la sostenibilidad sólo puede ser efectiva si los cambios de gran alcance en el estilo de vida complementan los avances tecnológicos. Sin embargo, las sociedades, economías y culturas existentes incitan a la expansión del consumo y el imperativo estructural de crecimiento en las economías de mercado competitivas inhibe el cambio social necesario."

"Somos Científicos y Científicas, ¡sácanos de aquí!" es una actividad de divulgación que, gracias a la colaboración de la Fundación Española para la Ciencia y la Tecnología (FECYT) y Gallomanor Communications, pone en contacto a personal investigador con estudiantes de 14 a 18 años a través de internet.

"Ayer viví una experiencia fabulosa que da cuenta de la potencia de las redes. Estaba buscando videos de experiencias concretas de sala y aula para mostrar en la práctica cómo se trabaja un proyecto didáctico y llevaba dos días buscando en la web sin demasiado éxito. Entonces se me ocurrió escribir un tuit a unos colegas españoles, referentes del Aprendizaje Basado en Proyectos, para preguntarles si podían sugerirme algunas experiencias. Inmediatamente comencé a recibir por Twitter contactos con enlaces a una enorme cantidad de experiencias riquísimas. Si bien algunas pocas estaban en video como buscaba, descubrí espectaculares blogs de colegas españoles que registran y comparten todas sus acciones en el aula o en la sala. ¡Pasé el día entero leyendo, analizando y aprendiendo! Me quedaron unas reflexiones sobre esta experiencia: 1.- El enorme poder de las redes para conformar comunidades de aprendizaje, es irremplazable y se opone el "reunionismo" característico de las instituciones educativas argentinas. Como define Éttiene Wenger (2001), las comunidades de práctica se caracterizan por "el compromiso mutuo, una empresa conjunta y un repertorio compartido". Yo agregaría también que la motivación que las reúne genera un entusiasmo que muchas veces contagia. 2.- La colaboración entre pares de los docentes españoles es un gran ejemplo: compartir planificaciones y experiencias se vivió como algo natural. En nuestro país aún sobrevive una tradición que limita la difusión de experiencias. Se suelen escuchar frases como "no lo publico porque me van a robar", "no muestro mis planificaciones más que a los directivos", etc. El saber compartido parece un poco alejado todavía de nuestra cultura docente. Será cuestión de barrer prejuicios y animarnos más, como en una de las iniciativas que intentamos poner en práctica con estudiantes del profesorado cuando abrí el blog "Planificar juntos". 3.- El potencial de los blog
