Solidaridad con los tiburones

SAN JOSE – Desde hace mucho tiempo se viene diciendo que sabemos más sobre la Luna que sobre los océanos. Después de todo, 12 personas han caminado sobre la superficie de la Luna, pero sólo tres se han adentrado en la parte más profunda del mar. Pero ahora parece que sabemos mucho menos acerca de los océanos de lo que pensábamos - y que tal vez hemos podido hacer incluso más daño de lo que creíamos.

En un estudio reciente  se observó que durante años se han subestimado las capturas de pescado. Este hecho debería captar la atención tanto de las organizaciones regionales de ordenación pesquera, que supervisan la pesca comercial en alta mar, como de las que velan por el cumplimiento de la Convención de las Naciones Unidas sobre la conservación de las especies migratorias de animales silvestres  (CMS), que abarca las especies migratorias en peligro de extinción.

Según la CMS, las especies que requieren hoy en día la protección más estricta – incluidas en el Apéndice I – figuran los tiburones blancos, además de las cinco especies de peces sierra y once especies de rayas. Las reuniones de la CMS sobre los tiburones migratorios, que tendrá lugar este mes en San José (Costa Rica), representan una importante oportunidad para avanzar en la elaboración de normas para asegurar la conservación y la utilización sostenible de estas especies, de forma que puedan seguir cumpliendo su función ecológica fundamental como depredadores apicales.

    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.
