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。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
