Ever hear of the industrial revolution? Take a second to imagine what cities were like in the mid-19th century with factories belching out black smoke from coal burning plants. Cities with open sewer systems that reeked of human feces. Small wonder that the lifespan of human beings were significantly shorter than today. The very fact that you would challenge me on this point only illustrates the ignorance of most people and how that effect the dialogue on climate change.
So because it was worse in certain cases back then it's perfectly fine today. Great logic, got it. Still didn't even address the actual question either.
