Is civilization teetering on the edge of a cliff? Or are we just climbing higher than ever? Most people who read the news would tell you that 2017 is one of the worst years in recent memory. We're facing a series of deeply troubling, even existential problems: fascism, terrorism, environmental collapse, racial and economic inequality, and more. Yet this narrative misses something important: by almost every meaningful measure, the modern world is better than it ever has been. In the United States, disease, crime, discrimination, and most forms of pollution are in long-term decline, while longevity and education keep rising and economic indicators are better than in any past generation. Worldwide, malnutrition and extreme poverty are at historic lows, and the risk of dying by war or violence is the lowest in human history.
