3) ...we managed to more than double our average life expectancy, simply by the application of our minds to the problem of human survival.
Can you verify this? I think you will find that this is misinformation.
Average life expectancy stats, when stripped of death at childbirth incidents, which is something that has improved dramatically, are much closer than is popularly assumed.
I'm not going to go to trouble of proving it... but I suggest to you that if you wish to use this in your argument that sooner or later someone will point out that this is not accurate and will be willing to prove it.
You might want to reconsider using this idea in your presentation.
very best,

I think the average life expectancy in America in 1800 was something like 35. Globally, the effect is even more pronounced. This is one of many similar graphs online:
Nor do I think it's invalid to include death at childbirth. Are you talking about the death of the woman during birth, or the child? Either way, the improvement after the Industrial Revolution was staggering. I think we take current living conditions somewhat for granted. In Britain, for instance, life was pretty grim before the Industrial Revolution, and it was fairly commonplace for kids to die before age 10. In the 80 or so years after 1780 the population of Britain almost tripled.
Another interesting stat I read (but can't find it now) went something (approximately!) like this: It took hundreds of thousands of years for the human population to reach one billion. After the Industrial Revolution, successive billions were added in 100 years, then 75, then 50 etc (actual number of years is different but I can't remember....you get the idea though!). This is without a doubt the greatest achievement of any species on Earth. No other species has been able to improve its living prospects so dramatically through the application of thought and action.
