Would you say the same thing about human suffering if the bronze age was 100 years later? And what about all the suffering and deaths from the pollution? Or the massive global wars fossil fuels enabled? Because without massive oil and gas reserves both WWI and WWII would have been far harder to sustain or commit to in the first place.

With such a massive shift in politics and technology with a lack of fossil fuels I think it is near impossible to compare the modern world to a world without those.
