“ Our annual homicide rate was 8.5 per 100,000. Eleven percent of us fell below the poverty line (as measured by consumption). And we spewed 20 million tons of sulfur dioxide and 34.5 million tons of particulate matter into the atmosphere. Fast forward to the most recent numbers available today. The homicide rate is 5.3 (a blip up from 4.4 in 2014). Three percent of us fall below the consumption poverty line. And we emit four million tons of sulfur dioxide and 20.6 million tons of particulates, despite generating more wealth and driving more miles. Globally, the 30-year scorecard also favors the present. In 1988, 23 wars raged, killing people at a rate of 3.4 per 100,000; today it’s 12 wars killing 1.2 per 100,000. The number of nuclear weapons has fallen from 60,780 to 10,325. In 1988, the world had just 45 democracies, embracing two billion people; today it has 103, embracing 4.1 billion. That year saw 46 oil spills; 2016, just five. And 37% of the population lived in extreme poverty, barely able to feed themselves, compared with 9.6% today. True, 2016 was a bad year for terrorism in Western Europe, with 238 deaths. But 1988 was even worse, with 440. When the Enlightenment began, a third of the children born in the richest parts of the world died before their fifth birthday; today, that fate befalls 6% of the children in the poorest parts. The world is about a hundred times wealthier today than it was two centuries ago, A century ago, the richest countries devoted 1% of their wealth to children, the poor, the sick and the aged; today they spend almost a quarter of it. Most of their poor today are fed, clothed and sheltered and have luxuries like smartphones and air conditioning that used to be unavailable to anyone, rich or poor. Poverty among racial minorities has fallen, and poverty among the elderly has plunged.”
