人性化的保护

巴黎——世界上的自然资源正在急剧减少。世界各地的动植物物种正在以前所未有的速度消失——消失速度是自然灭绝速度的100到1,000倍。

地球上最危险的生态系统处于发展中国家,因此对它们的保护需要仰仗世界上某些最贫困国家的力量。反过来,贫困人口往往从周边自然环境的恶化中最先受损。但是在发展中国家,迫在眉睫的经济需要却往往能够压倒长期的必要需求,因此对脆弱环境的保护很少能够成为国家优先考虑的目标。

全球发展中国家的生物多样性既能为所在国家服务,也能令世界各国得到好处。能为当地人服务,是因为经济上最脆弱的民众往往需要依赖周围环境中的生物资源才能维持生计,他们的食物、能源和收入都需要从周围的环境中获取。世界银行估计,自然资源能够占到低收入国家财富总量的四分之一,而在高度发达国家中自然资源仅仅构成3%的财富比例。说它具有全球性,是因为自然生态系统能够提供的一系列服务,包括洁净空气和新鲜淡水,能够使远离国界的民众都从中获益。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
