Human Progress
What improved, what powered the gains, and what the gains cost.
Human progress · planetary strain
Living conditions improved and human capabilities expanded, while the systems behind them grew into a planetary force.
Progress was real and costly. Because it was built through choices, tools, and institutions, it can also be redirected.
Evidence and limits
The earliest points are often historical reconstructions; recent points draw more heavily on direct measurement, surveys, censuses, and administrative records.
Read the lines for broad direction rather than year-by-year precision. Each measure keeps its own dates and units, so heights and slopes should not be compared as though they shared one scale.
Living conditions
Living conditions rose sharply
The first question is simple and human: did ordinary lives become longer, safer, more literate, and less poor?

Capabilities
New capabilities diffused fast
Communication, energy, food production, and clean-energy manufacturing show how quickly practical technologies can spread once the supporting systems exist.
These gains did not arrive as one smooth moral awakening. They came through public health, agriculture, fossil energy, institutions, vaccines, schooling, sanitation, trade, and countless local adaptations. This view shifts from outcomes to capabilities: the tools that let information, food, energy, and communication move at new speeds.

These measures put the progress story beside its physical shadow: the scale of human activity and ecological change.
But capability is not weightless. A world with more people living longer, eating more, traveling farther, and using more machines also becomes a larger physical presence on the planet. The same historical engine that lifted living standards increased energy use, material extraction, emissions, and pressure on other forms of life.

Before cities or writing, humans learned to turn natural materials into tools, heat, food safety, and shared protected space.

The honest conclusion is neither triumphalism nor despair. Human life improved in ways that would have been hard to imagine in much of the past, through systems that also changed the planet at dangerous scale. The task now is to keep the human gains while changing the machinery underneath them.
The averages cannot tell us who received the gains or who gained the power to shape what came next. Continue with The Unequal Inheritance.
