Why does light from stars make us look back in time?

Because the light takes a long time to reach Earth, allowing us to see the past.

How has the global population growth rate changed since the 1960s?

The growth rate has been decreasing steadily over the years.

Economic strain, social security system failures, and increased labor costs can occur.

By attracting global talent, investing in human capital, and rethinking work at older ages.

Fertility rates are dropping globally, leading to reduced populations in many countries.

Light from stars reaching Earth after a long time allows us to glimpse into the past, much like how population changes reflect shifts in societal structures and economic systems over time.
The global trend of decreasing fertility rates leading to aging populations necessitates proactive measures like attracting international talent, investing in human capital, and redefining work norms to address the challenges posed by demographic shifts.

Light from stars in the night sky reaches Earth after a long time, making us look back in time.
Earth's population is similar to stars, with some regions experiencing or soon facing population decline.
Despite the global population growing to around 9 or 10 billion, the growth rate has been decreasing since the 1960s.
Worldwide, fertility rates are dropping, with various countries projected to have significantly reduced populations by the end of the century.
Many countries are already facing an aging population, with a shift towards low fertility and depopulation.
Failure to adapt to these demographic changes can lead to economic strain, social security system failures, and increased labor costs.
In a resilient world, countries can attract talent globally, invest in human capital, and rethink work at older ages to navigate demographic shifts successfully.
