Tötet die Killermoskitos

SINGAPUR – Moskitos sind zwar klein, aber ihr Stich hat schwere Folgen. Sie verbreiten eine Vielzahl von Krankheiten – wie Chikungunya, Dengue, Malaria, Gelbfieber, West-Nil-Fieber und das Zika-Virus – denen insgesamt jedes Jahr Millionen von Menschen zum Opfer fallen. Die Malaria ist (hinter Tuberkulose und AIDS) eine der weltweit tödlichsten Krankheiten. 2015 fielen ihr 429.000 Menschen zum Opfer. Angesichts eines derart riesigen Problems muss die Ausrottung von Moskitos – und der von ihnen übertragenen Krankheiten – in der Entwicklungshilfe oberste Priorität haben.

Insbesondere in den Entwicklungsländern gehören die Moskitos nach Aussage der Weltgesundheitsorganisation zu den stärksten Gefahren für die öffentliche Gesundheit. Wie aus einer Abbildung im Blog von Bill Gates aus dem letzten Jahr hervorgeht, sind Moskitos jedes Jahr für 830.000 menschliche Todesfälle verantwortlich – 250.000 mehr, als von unseren Mitmenschen verursacht werden.

Neben den massiven menschlichen Verlusten verursachen die von Moskitos übertragenen Krankheiten auch erhebliche wirtschaftliche Kosten. Was die infizierten Menschen betrifft, sind darin Kosten für Behandlungen, Krankenhauskosten, Kosten für den Transport von Krankenhaus und wieder zurück, Kosten für die Abwesenheit vom Arbeitsplatz sowie solche für Insektenspray und Moskitonetze enthalten.

    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.
