As a result, some babies died because of unsterile water, bottles and nipples, and many others
simply died of starvation, while parents looked on helplessly.
They didn't have any knowledge
of nutrition, they weren't able to eat nutritious, calorie dense food whenever they wanted due to the absence
of agriculture, and their immune systems were likely weaker than ours (living together in large numbers placed enormous selective pressure on our early agricultural ancestors to develop strong immune systems, keep in mind that early human civilizations did not have indoor plumbing... so they were sometimes exposed to fecal matter both from fellow humans and from livestock and they didn't have the kinds
of disinfectants and anti-biotics we have today,) so for them to have serious health complications makes perfect sense, nature can be very harsh and doesn't care how long its been since your last meal or what your calorie and micro nutrient needs are... a lot
of people
died at very young ages back then
simply because they got sick and didn't have proper medical treatment or due to malnutrition or
starvation.
The truth
of the matter is that if the world reduces the use
of fossil fuels there will be
starvation on a broad scale, and many more people will
die simply because they lack the energy for clean and safe living.
