Die Rettung der Fischbestände

Es fällt schwer, die Zukunft der Fischbestände optimistisch zu sehen. Der weltweite Hochseefischfang nahm nach dem Zweiten Weltkrieg rasch zu, stagnierte dann in den späten achtziger Jahren des vorigen Jahrhunderts und ging seither weiter zurück. Dieser Rückgang wird nur schwer zu stoppen sein.

Die rasche Dezimierung der Fischbestände ist die unausbleibliche Folge einer immer ausgefeilteren Fischereitechnik, mit der man aufgrund wachsender Nachfrage durch Bevölkerungswachstum und höherer Einkommen der Menschen auf die schwindenden Fisch- und Meerestierbestände losgeht. Bisher wurde der Rückgang der Fischbestände durch massive Fischimporte aus Entwicklungsländern und durch Produkte kaschiert, die es früher nicht gab, wie beispielsweise Zuchtlachs.

Aber auch in den Entwicklungsländern gerät das Überfischen der Meere zu einem Problem. Der Fischerei stehen daher in nächster Zukunft weltweit drastische Veränderungen ins Haus. Ein deutliches Anzeichen dieses Problems ist das ,,Abfischen am Beginn der marinen Nahrungskette'' - also der Trend, Fische und Weichtiere zu fangen, die vielfach zur Beute der größeren Fische gehören, die man früher gefangen hatte.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
