过去75年迎来了人类历史上人类福祉的最大幅改善。但在过去十年中，大部分进展都停滞不进了。这种情况发生的同时，富裕世界将注意力转移到了气候变化上。这不是巧合，必须改变这种状况。
The last 75 years have brought the greatest improvement of human welfare in history. But over the past decade, much of that progress has stalled. This happened at the same time that the rich world shifted its attention to climate change. This is not a coincidence and it has to change.
以极端贫困为例，长期以来，极端贫困被定义为每天的生活费不足一美元。1950年，超过一半的人类都处于那种贫困状态。如今这一比例为7.6%，是有记录以来的最低水平。平均受教育年限几乎增加了两倍，从3.2年增至近9年。电力普及率大幅飙升。问题依然存在，但取得的成就是惊人的。
Consider extreme poverty, long defined as living on less than a dollar a day. In 1950, more than half of humanity was that poor. Today the share is 7.6%, the lowest ever recorded. Average schooling has almost tripled, from 3.2 years to nearly 9. Electricity access has soared. Problems remain, but the gains have been spectacular.
如今，发展速度已放缓至爬行状态。经过近两个世纪的贫困减少，自2016年以来，穷人的数量一直没有变动。根据世界银行的数据，全球进展正处于1950年以来最慢的速度。
Now development has slowed to a crawl. After almost two centuries of declining poverty, the number of poor people hasn’t budged since 2016. Global progress is at its slowest pace since 1950, according to the World Bank.
