养鱼场杀手

根据最近由联合国粮农组织发表的一份报告显示我们所吃的鱼几乎有一半来自养鱼场而不是野生的。在此方面,养殖鲑鱼的消费量增长应该是最快的,它的产量在过去20年间急剧上升了大约300%。

然而,鲑鱼是食肉动物,为了满足这些大批的人工养殖的鱼类的贪婪的食欲,水产业开始越来越多地把他们的注意力放在了一种通常叫做南极磷虾的很小的甲壳纲动物身上。但是那对于海豹、阿黛利企鹅、座头鲸、蓝鲸以及其他许多物种来说却是一个坏消息,因为绝大部分南极海洋生态系统的生物体依靠吃磷虾或者其他吃磷虾的东西为生。

这种在南大洋冰冷的海水里发现的磷虾是鱼的油脂和饲料的一种重要成分。不幸的是,最近的研究显示被扩大的磷虾捕捉会威胁到南极的生态系统。来自世界上主要捕鱼国的代表今年秋天聚集在澳大利亚商议限制磷虾的捕捉量以此来帮助那些以磷虾为生的生物。

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
