El imperativo en pro de la diversidad biológica

LONDRES – En este año, declarado Año Internacional de la Diversidad Biológica por las Naciones Unidas y en el que se celebrará la reunión del Convenio sobre la Diversidad Biológica en el Japón, está claro que las amenazas al medio ambiente que afrontamos son muy graves y van en aumento y que nunca había sido tan urgente la necesidad de actuar.

Nuestras vidas y las de todos los demás seres vivos de este planeta forman parte de la diversidad biológica y dependen de ella. Dicho de forma sencilla, la diversidad biológica es la trama de la vida, compuesta por todos los organismos que encontramos en todos los hábitats, desde los peces de los océanos profundos hasta las aves de los bosques tropicales y todo lo que se encuentra entre medias.

La diversidad de plantas y hongos forma parte de la base misma de la diversidad biológica y de ellos dependen todas las demás formas de vida. Las plantas absorben el dióxido de carbono y producen oxígeno, con lo que proporcionan el aire que respiramos y contribuyen a regular el clima. Brindan alimentos, medicinas, combustibles, abrigos, agua potable y suelos fértiles. La diversidad vegetal nos mantiene ahora y en el futuro nos permitirá adaptarnos, innovar y en última instancia sobrevivir.

    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.
