" Ocean Acidification is sometimes referred to as Global Warming's Equally Evil Twin. The irony is intentional and fair enough as far as it goes... No single mechanism explains all the mass extinctions in the record and yet changes in ocean chemistry seem to be a pretty good predictor. Ocean Acidification played a role in at least 2 of the Big Five Extinctions: the End-Permian and the End-Triassic. And quite possibly it was a major factor in a third, the End-Cretaceous. ...Why is ocean acidification so dangerous? The question is tough to answer only because the list of reasons is so long. Depending on how tightly organisms are able to regulate their internal chemistry, acidification may affect such basic processes as metabolism, enzyme activity, and protein function. Because it will change the makeup of microbial communities, it will alter the availability of key nutrients, like iron and nitrogen. For similar reasons, it will change the amount of light that passes through the water, and for somewhat different reasons, it will alter the way sound propagates. (In general, acidification is expected to make the seas noisier.) It seems likely to promote the growth of toxic algae. It will impact photosynthesis—many plant species are apt to benefit from elevated CO2 levels—and it will alter the compounds formed by dissolved metals, in some cases in ways that could be poisonous.
Of the myriad possible impacts, probably the most significant involves the group of creatures known as calcifiers. (The term calcifier applies to any organism that builds a shell or external skeleton or, in the case of plants, a kind of internal scaffolding out of the mineral calcium carbonate.)...
Ocean acidification increases the cost of calcification by reducing the number of carbonate ions available to organisms that build shells or exoskeletons. Imagine trying to build a house while someone keeps stealing your bricks. The more acidified the water, the greater the energy that’s required to complete the necessary steps. At a certain point, the water becomes positively corrosive, and solid calcium carbonate begins to dissolve. This is why the limpets that wander too close to the vents at Castello Aragonese end up with holes in their shells.
According to geologists who work in the area, the vents have been spewing carbon dioxide for at least several hundred years, maybe longer. Any mussel or barnacle or keel worm that can adapt to lower pH in a time frame of centuries presumably already would have done so. “You give them generations on generations to survive in these conditions, and yet they’re not there,” Hall-Spencer observed.

" Currently the best educated and the brightest minds of any nation are not among its elected, but among its public, and in much greater numbers.But even having a great number of the best and the brightest amongst us does not make us capable of installing a working version of direct democracy right away. People who claim that it does, may be there to voluntarily or involuntarily damage the credibility of direct democracy.Direct democracy needs a yet inexistent infrastructure to support the new mechanism that will render the public capable of constituting the experience necessary to domesticate direct democracy, without destabilizing our societies with needless haste, emotions and fractures. One way of doing it may be the constitution of a nation-wide, internet reliant hence fluid, non-political organism parallel but totally hermetic to our representative democracies, with a unique objective: creating the means, platforms and protocols necessary for the public and all the specialists it contains, to communicate horizontally.The public may decide to keep for the moment our representative democracies, but in parallel create an experimental version of direct democracy until we all acquire the necessary perspective and invent new working mechanisms of self-governance. Later the public may decide to have both representative and direct democracies sharing governance for a time, and experience first-hand the advantages and disadvantages of both systems before deciding where to go from there.

" If one looks at modern society, it is obvious that in order to live, the great majority of people are forced to sell their labour power. All the physical and intellectual capacities existing in human beings, in their personalities, which must be set in motion to produce useful things, can only be used if they are sold in exchange for wages. Labour power is usually perceived as a commodity bought and sold nearly like all others. The existence of exchange and wage-labour seems normal, inevitable. Yet the introduction of wage-labour involved conflict, resistance, and bloodshed. The separation of the worker from the means of production, now an accepted fact of life, took a long time and was accomplished by force.In England, in the Netherlands, in France, from the sixteenth century on, economic and political violence expropriated craftsmen and peasants, repressed indigence and vagrancy, imposed wage-labour on the poor. Between 1930 and 1950, Russia decreed a labour code which included capital punishment in order to organise the transition of millions of peasants to industrial wage-labour in less than a few decades. Seemingly normal facts: that an individual has nothing but his labour power, that he must sell it to a business unit to be able to live, that everything is a commodity, that social relations revolve around market exchange… such facts now taken for granted result from a long, brutal process.By means of its school system and its ideological and political life, contemporary society hides the past and present violence on which this situation rests. It conceals both its origin and the mechanism which enables it to function. Everything appears as a free contract in which the individual, as a seller of labour power, encounters the factory, the shop or the office. The existence of the commodity seems to be an obvious and natural phenomenon, and the periodic major and minor disasters it causes are often regarded as quasi-natural calamities. Goods are destroyed to maintain their prices, existing capacities are left to rot, while elementary needs remain unfulfilled. Yet the main thing that the system hides is not the existence of exploitation or class (that is not too hard to see), nor its horrors (modern society is quite good at turning them into media show). It is not even that the wage labour/capital relationship causes unrest and rebellion (that also is fairly plain to see). The main thing it conceals is that insubordination and revolt could be large and deep enough to do away with this relationship and make another world possible. "

" Something, which the police called a bomb, had exploded in his shed. Investigations were begun, and the efforts of the authorities were soon to be categorized by the appropriate officals as " feverish" , for bombs began to go off all over the place. The police collected fragments of the exploded bombs, and the press, anxious to help the police in their work, published impressive pictures of the fragments as well as a drawing of a reconstructed bomb together with a very detailed description of how it had been made.The police had done a really first-rate job. Even my brother and myself, both of us extremely untalented men in technical matters, could easily grasp how the bomb makers had gone to work. A large quantity of ordinary black gunpowder, such as is the be found in the cartridges sold for shoutguns, was encased in plasticine; in it was embedded an explosive cap, of the type used in hand grenades during the war, at the end of a thin wire; the other end of the wire was joined to the battery of a pocket flashlight -- obtainable at any village store -- and thence to the alarm mechanism of an ordinary alarm clock. The whole contratation was packed into a soapbox. Of course my brother did his duty as a journalist.He published the police report, together with the illustrations, on page one. It was not my brother's doing that this issue of the paper had a most spectacular success and that for weeks men were still buying it; no. the credit for that must go to the police; they had done their bit to ensure that the peasantry of Schleswig-Holstein would have a healthy occupation during the long winter evenings. Instead of just sitting and indulging in stupid thoughts, or doing crossword puzzles, or assembling to hear inflamatory speeches, the peasantery was henceforth quetly and busily engaged in procuring soapboxes and alarm clock and flashlight batteries. And then the bombs really began to go of.... Nobody ever asked me what I was actually doing in Schleswig=Holstein, save perhaps Dr. Hirschfeldt, a high official in the Prussian Ministry of the Interior, who had recently taken to frequenting Salinger's salon. Occasionally, and casually, he would glance at ne with his green eyes an honour me with a question, such as: " And what are the peasants up to in the north?" To which I would usually only reply: " Thank you for your interest. According to the statistics, the standard of living is going up -- in particular, there has been in increased demand for alarm clocks. "
