It is true that without industrialisation we would not be able to mass-produce medicines and medical technology and equipment. However, the industrial revolution could still have happened without the healthcare element of it, and if this had happened without it, the child mortality rate would still have been high. On top of that, the adult mortality rate would have still been high. As such, populations would not have boomed even remotely to the levels that they did and have.
For example, if you take away just vaccines, antibiotics, and antiseptic creams alone, then overnight the child mortality rate would rocket, and a simple cut that gets infected could lead to the death of a child. Also, the same would be true for adults.
I can’t remember where I read it, but I believe via simple medical treatments alone, so mostly over-the-counter ones, virtually every child by the time they reach the age 15, have likely been saved up to 10 to 15 times from death, and yet because the things that might have caused their deaths are now so innocuous to us and so easily treated, we don’t even realise just how many times they have been saved from death.
The best example I think that shows just how much the healthcare revolution played a part in populations booming is the smallpox vaccine alone, which was invented in 1798 by Edward Jenner. Due to the fact it stopped so many children from dying it was one of the main elements that led to the substantial population boom of the 1800s.
Anyhow, thanks for reading! Much appreciated, and you are right, without the Industrial Revolution, the healthcare revolution could not have happened.
