But every one was burning then not so now, actually few by contrast.

Before we were burning trees, now we burn oil, coal, and gas.

With less polution. I have no polution control device on my fireplace and I
doubt way back when there were any such devices either. Ther is all kind of
polution control devices on oil, coal, gas, and gasoline burning machines.



From 1850 to 2000, the total energy consumption of the USA increased by
a factor of 50. Of course a large amount of that is due to population
increase, but the per-capita energy consumption has increased roughly 4x
over that period.

So.. much cleaner energy consumption compared to way back when.

Cleaner in what sense? As the US switched from agrarian to modern it
uses 4x as much energy per person. How is that cleaner overall?

what,,,,, 4 times more people using cleaner burning fuels than wood.....
