Herausforderung Biodiversität

LONDON – 2010 wurde von den Vereinten Nationen zum Internationalen Jahr der biologischen Vielfalt erklärt und in Japan findet die Vertragsstaatenkonferenz zum Übereinkommen über die biologische Vielfalt statt. Es zeigt sich deutlich, dass wir mit schwerwiegenden und zunehmenden umweltpolitischen Herausforderungen konfrontiert sind und dass nie dringenderer Handlungsbedarf bestand als jetzt.

Unser Leben und das aller anderen Geschöpfe auf diesem Planeten ist Teil der biologischen Vielfalt und zugleich von ihr abhängig. Einfach gesagt, ist Biodiversität das Netz des Lebens, in dem alle Organismen in jedem Lebensraum miteinander verflochten sind, von den Fischen in der Tiefsee bis zu den Vögeln in den tropischen Regenwäldern und allem, was dazwischen ist.

Die Vielfalt der Pflanzen und Pilze bildet die Grundlage der Biodiversität und eben davon hängt alles andere Leben ab. Pflanzen absorbieren Kohlendioxid und produzieren Sauerstoff und liefern uns so die Luft zum Atmen und tragen zur Regulierung des Klimas bei. Sie liefern Nahrung, Arzneimittel, Treibstoff, Obdach, sauberes Wasser und fruchtbaren Boden. Die Vielfalt der Pflanzen erhält uns aufrecht und wird es uns in Zukunft ermöglichen uns anzupassen, Neuerungen einzuführen und letztendlich zu überleben.

    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.
