公海上的死亡与希望

加拿大哈利法克斯——鲨鱼及其远亲鰩鱼在恐龙出现前就已经在地球上生活。它们躲过了消灭霸王龙及其他所有物种的灾难性大灭绝,也躲过了消灭96%海洋物种的二叠纪-三叠纪大灭绝。即使是锤头鲨等较新进化的鲨鱼谱系在地球上的生存时间也已经超过3,000万年。

但短短数十年后,四分之一的鲨鱼和鰩鱼就将面临着灭顶之灾。这是我们的错——保护鲨鱼是我们义不容辞的职责。

并非只有鲨鱼和鰩鱼在劫难逃。海洋生物多样性的其他部分——尤其是珊瑚、海洋哺乳动物、海鸟和海龟—— 也正在疲于应对人类的压力。结果导致海洋生态系统稳定性和效率下降,并有可能面临四分五裂的威胁。

    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.
