    Pollution has been a problem since the advent of fire. Neanderthals burning fires inside caves were exposed to intense indoor pollution. In more modern times, Native Americans living in what we now call Los Angeles had enormous problems with air pollution.

    Actually, there weren’t that many problems until the Industrial Revolution started. Chemical fires (natural fires don’t really cause enough pollution to make a difference) were used often in factories before people knew the dangers that the smoke could cause. It would be over a hundred years later, in the 1960’s or so, when people would start to understand the pollution being caused. However, it’s also due to the industrial revolution that we have the technology we use now, as there were great leaps and bounds in scientific knowledge.
