水资源之战

对于人类和所有生命形式的未来,还有什么比水更重要的呢?自然界的水资源十分丰富,大多数人即便再活一万年也不会认真考虑水的问题。

我们抽取水、利用水,再把废水排放到江河海洋。但很快我们就会缺少淡水,因为淡水只占全球水资源总量的3%。只要想一想石油会引发什么样的争斗,缺水所带来的灾难就会令人不寒而栗。尽管拉丁美洲的水资源比较丰富,但其它地方的情况却没有那么乐观。欧洲正处在缺水的边缘,而水资源短缺的问题在非洲、中亚和中国已经迫在眉睫。

近二三十年来我们才开始意识到问题有多么严重,而这要归功于像世界水资源论坛这样的节水组织,该组织第四届年会今年3月刚刚召开。遗憾的是,该论坛还算不上官方组织,也没有决策权。但它为思想和辩论提供的土壤至少有一项极大的好处:那就是使公众和决策者意识到水资源问题的严重性。

    The Brexit Surrender

  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.
