    Growth has only really slowed this century and it's plummeting, there's a graph in your extract that shows that. Even the graphs that show long term growth show a recent flattening out. Had exponential growth continued at the same rates as in the second half of the 20th century, it would have been unsustainable but that's not what's happened or happening. The current explanation is that as industrialisation, urbanisation and education, particularly of women, increases numbers of children diminish, on a farm, children are cheap labour, in the city they become an almost unaffordable luxury. In Australia, the current fertility rate is 1.58 per woman. Worldwide it's still around 2.4 but dropped from 5.6 in 1970.
    Well in 1950 the population was 2.5 billion. It took the length of human history to get there.

    In the 73 years since we've seen a 300 + percent increase to over 8 billion.

    I'd argue it's because countries like India have a new middle class and advances in medicines / social care that have enabled this.

    Humans are flourishing guys!

      Yes, the chances of offspring surviving increase in correlation with wealth, so people don't reproduce as much as they get wealthier. As middle classes expand birth rates decline.

      There's generally never been a better time to be alive than today, unless you're stuck in poverty.
      TF is this?.........Obviously you're not a golfer.

        If only those communist academics didn't invent the atom bomb we'd have more people!

          And it's that growth that got us in this mess. We'd need a substantial decline to get it back.
