The Lorax - Teaching Children Philosophy Author: Dr. Seuss Publisher: Random House Summary by jayme johnson The Lorax has gone. Guidelines for Philosophical Discussion The Lorax , by Dr. One underlying message contained within the Lorax that is a good source of philosophical discussion is the idea of the interconnectedness of the things that live in an ecosystem. Answers to many of the questions about our social responsibility to the ecosystem seem currently to be driven by the notion of sustainability . So far the discussion has been geared to the idea of social responsibility , but we can also ask about what the nature of social responsibility itself is. One final interesting philosophical topic that gets raised in the Lorax might be called the intrinsic value argument for environmental preservation . Questions for Philosophical Discussion The Lorax tries to speak for the trees. When the Lorax first appears to speak on behalf of the tress, the Once-ler claims he is doing no harm by cutting down Truffula Trees to make Thneeds.

The Environmentalist Unsere Arbeitsweise - Novartis Stiftung für Nachhaltige Entwicklung Unsere Arbeitsweise (Flash-Animation, grosse Ansicht) Durch die synergistische Verknüpfung von praktischer Projekt- und Programmarbeit im Gesundheitsbereich, Think-Tank-Aktivitäten (Forschung, Publikationen, Beratung und Informationsarbeit) sowie entwicklungspolitischem Dialog und Networking suchen wir nach neuen Lösungen altbekannter entwicklungs- und gesellschaftspolitischer Probleme. A Disappearing Planet Given the natural extinction rate, we would not expect more than one mammal species go extinct per century. However according to the scientists, 1,469 are currently in danger of extinction in that time. Primates are highly at risk, especially the lemur family. Rhinos, bears, and big cats are also in trouble. According to the natural extinction rate, we should not see more than one reptile extinction per century. According to the natural extinction rate, we should not see more than one amphibian extinction per century. According to the natural extinction rate, we should not see more than one bird extinction per century.

Association pour la sauvegarde de la biodiversité TENDUA a été créée en 2008, après un voyage en Inde où, en dépit de nombreux parcs nationaux, la faune sauvage et ses habitats sont menacés. Le constat est malheureusement planétaire : partout dans le monde, la biodiversité est en danger, sur terre et dans les mers. La 6e extinction majeure de biodiversité est en cours : en 150 ans l’homme a réussi à détruire son environnement comme il ne l’avait jamais fait auparavant. Les précédentes extinctions connues des scientifiques étaient le résultat d’un processus évolutionnaire ; or aujourd’hui, l’équilibre de la planète est menacé par les activités humaines. En août 2013, il a été estimé que l’humanité, par sa consommation effrénée, a dépassé la capacité de régénération de la Terre. Cela étant, nous n’avons plus le temps d’être pessimistes. Une nouvelle relation entre l’homme et la nature TENDUA propose à chacun de réfléchir à un nouveau type de relation entre l’homme et la nature. Adhésions et partenariats Comment adhérer ?

FAO: FAO Home Ocean Acidification | EARTH 103: Earth in the Future Background Increasing levels of CO2 in the atmosphere are slowly causing the surface of the ocean to become more acidic. This is because the ocean absorbs some of the CO2, forming a weak carbonic acid. At present, the ocean absorbs about a third of fossil fuel emissions, but this amount is likely to increase to 90% in the future. Over the last century, the average pH of the ocean has decreased, and there are hints that the current levels are beginning to impact organisms that make their shells out of the minerals aragonite and calcite (both composed of CaCO3). Coral reefs that are made of the mineral aragonite are highly vulnerable to ocean acidification. Changes in atmospheric CO2 and consequences on the oceans. The following video provides a thorough overview of the potential impact of acidification on the oceans. Chemistry 101 As we discussed in Module 5 on the Carbon Cycle, the absorption of CO2 in the ocean forms weak carbonic acid (H2CO3). Credit: National Academies

SFE : la Société Française d'Écologie Press Clips: Forget the Fragile Lands: It’s Time to Hit the City! by Harriet Festing A popular guidebook on Sri Lanka describes Colombo (the capital) as an “odorous crush that will either instantly repel or draw you in by its charms.” If you’re only on a short trip to Sri Lanka, the book goes on to say, “you may wish to pass Colombo by.” The message is clear – get out of the city and onto the beaches if you want to enjoy your visit. Here lies the problem of tourism, and ecotourism in particular, in the developing world. Ecotourism has the potential to distort and pollute the very cultures it purports to be concerned about. The truth is that the most sustainable forms of tourism are urban. For Sri Lanka, the false promises in the name of ecotourism has had worrying consequences. But does it have to be that way? New York is one of the most sustainable tourist attractions in the world. In November, Project for Public Spaces (PPS) hosted a high-level delegation of Armenians for a ten-day training course in New York City on Placemaking.
