Akhir Kehidupan dan Harapan di Laut Lepas

HALIFAX, KANADA – Kehidupan hiu dan kerabat dekatnya, ikan pari, sudah dimulai bahkan sebelum dinosaurus ada. Jenis hiu dan pari bertahan dari malapetaka kepunahan massal yang membinasakan Tyrannosaurus Rex dan seluruh dinosaurus lainnya, termasuk kepunahan Permian-Triassic yang memusnahkan 96% spesies laut. Bahkan garis keturunan hiu yang lebih baru berevolusi, seperti hiu martil, sudah ada selama lebih dari 30 juta tahun.

Namun dalam beberapa dekade saja, seperempat jenis hiu dan pari terancam punah. Kejadian ini timbul karena kesalahan kita sendiri – dan menjadi tanggung jawab kita untuk memperbaikinya.

Populasi hiu dan pari bukan satu-satunya spesies yang terancam punah. Sebagian besar keanekaragaman hayati di laut – khususnya karang, mamalia laut, burung laut, dan penyu – juga kesulitan melawan tekanan manusia. Sebagai akibatnya, ekosistem laut berisiko menjadi terurai, tidak stabil dan kurang produktif.

  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.

    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.

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.
