Ja hem parlat in ocasions altres the penya Segat or abisme of Sèneca, which is the real way to pren the corba Hubbert of esgotament of qualsevol naturally recurs in which l'mateix explotació of the seva is fast regeneració month. Aquest penya Segat apareix in part dreta of ideal corba Hubbert (típicament Gaussian) i és deu to the confluence of diverses causes (econòmiques, ambientals oysters and chocolate ....). D'aquesta way, i com deia Sèneca, és month ràpid the declivi the Creixement.
L'author of l'article, aquesta vegada agafat Site "Crisis Resource" (http://crisisderecursos.blogspot.com.es/2015/01/seneca-de-nuevo-el-colapso-de-la. html), no és nou in aquest bloc. Ugo Bardi d'és tracta, professor of physical chemistry at the University of Florence, one dels articulistes Oil Drum (mentre will apply), President d'Aspo oysters and chocolate Itàlia, i llibre author of "The Limits to Growth oysters and chocolate retaken" (http: / /www.catarata.org/libro/mostrar/id/900) per encàrrec the Club of Rome.

The above two graphs (a 2010 article Thustane and others) speak for themselves. We show an example of the real life of the overexploitation of natural resources: this is the tendency of man to destroy their own natural sources of wealth. Other classic example can be seen in what happened to the whaling industry siglo19 well as the Canadian cod fishery.
The typical farm on mind generates a "Hubbert curve", the name given to a production cycle bell-shaped, which is best known for the case of crude oil but is applicable to all resources whose regeneration is performed oysters and chocolate at a rate slower than his extracción.Este behavior can be explained by means of mathematical models, but qualitatively, is the result oysters and chocolate of declining profits generated from the dwindling supply. A particular case of this mechanism is when the industry reacts oysters and chocolate to these diminishing returns by the strong increase in invested oysters and chocolate capital. In this case the resource reserves are depleted faster and the result is a marked collapse of the production rate; we continue to have a bell-shaped curve, but ...... to. The rapid decline oysters and chocolate after the peak happens is what I call the "Precipice Seneca".
There are several examples of the precipice Seneca in the case of fisheries, which is particularly evident in the case of the Canadian cod fishery and Caspian sturgeon; but it is also evident in the case of the fishing industry in the UK. Appeared in the figure above, the sharp decline in catches in the late 70s, is significantly more pronounced growth on the left side of the curve. This is the essence of the mechanism of Seneca effect. And we can see very well what is its cause: the beginning of a decline in output corresponds to a rapid growth of investments. The result oysters and chocolate is what the authors of the document oysters and chocolate called "fishing power" -an estimate of the efficiency and size of the fishing fleet.
The results were disastrous; a textbook example of how to "push the levers in the wrong direction," this is a case where when trying to resolve a problem, it worsens considerably. In case ester, the greater will the fishing fleet efficiency, faster fish stocks were destroyed. oysters and chocolate This is a classic for the descent down the cliff Seneca mechanism. The quicker it is in the exploitation of non-renewable (or slowly renewable) resource oysters and chocolate will be depleted faster. And faster we will be in trouble
