The Story of Stuff exposes the connections between a huge number of environmental and social issues, and calls us together to create a more sustainable and just world. @ www.storyofstuff.org you can download this and other movies, scripts and more • Story of Bottled Water • Story of Cap and Trade • Story of Cosmetics • Story of Electronics Info - Video Consumerism • Shop Till You Drop – The Crisis of Consumerism Are we too materialistic? Are we willfully trashing the planet in our pursuit of things? And what's the source of all this frenetic consumer energy and desire anyway? Shop 'Til You Drop challenges us to confront these questions head-on. arte.tv and youtube.com • Prêt à jeter / Kaufen für die Müllhalde Glühbirnen, Nylonstrümpfe, Drucker, Mobiltelefone --bei den meisten dieser Produkte ist das Abnutzungsdatum bereits geplant. Die Verbraucher sollen veranlasst werden, lieber einen neuen Artikel zu kaufen, als den defekten reparieren zu lassen. Die bewusste Verkürzung der Lebensdauer eines Industrieerzeugnisses nennt man "geplante Obsoleszenz". Bereits 1928 schrieb eine Werbezeitschrift unumwunden: "Ein Artikel, der sich nicht abnutzt, ist eine Tragödie fürs Geschäft". Die Dokumentation erzählt die Geschichte der geplanten Obsoleszenz. arte.tv und youtube.com Info - Video Peak Oil • A Crude Awakening – The Oil Crash (DVD) The film tells the story of how our civilization’s addiction to oil puts it on a collision course with geology. It visits with the world’s top experts and comes to a startling, but logical conclusion – our industrial society, built on cheap and readily available oil, must be completely re-imagined and overhauled. Economics • Tomáš Sedláček – Ökonomie: nichts als Moral Warum die Ökonomie ein kulturelles Phänomen ist Der 34-jährige Tscheche Sedláček packt die Ökonomie an ihren Wurzeln: in den Mythen und der Religion, in Theologie und Philosophie, in Psychologie, Literatur und Film. Katja Gentinetta unternimmt mit ihm einen Streifzug durch die Höhenflüge und Abgründe der Ökonomie und fragt, was wir denn ändern müssten, um dem Krisenmodus zu entkommen. Podcast: sternstunden.sf.ch, Sternstunde Philosophie vom 05.02.2012 Info - Audio Goldgrube Abfall Wir produzieren immer mehr Abfall. Das ist nicht für alle schlecht. Für die Energieproduzenten sind die wachsenden Müllberge ein gutes Geschäft. Hinzu kommt die Idee des «Urban Mining»: aus dem Abfall können Rohstoffe wieder gewonnen werden. Input reist dem Abfall nach, beleuchtet, wer wie vom Abfall profitiert und will wissen, wie wertvoll Müll wirklich ist. Podcast: drs3.ch, Input vom 30.10.2011 Landfrass / Zersiedelung Wird weiter gebaut wie bisher, so sieht die Schweiz in 200 Jahren aus wie Tokio. Ein Bild, von dem niemand träumt. Dennoch geht die Zersiedlung ungebremst weiter. Zu viele profitieren davon. Was dabei herauskommt, zeigt uns der Architekturkritiker Benedikt Loderer. Wir erfahren von einem Geografen, wie es überhaupt so weit kommen konnte, und wir beleuchten mit einem Stadtforscher, wie die Zukunft des verdichteten Wohnens ausschauen könnte.
