Not sure how CO2 emissions equivocate with violent crime, but if we're gonna go there...
The majority of homicides and violent crime in the US occur in proverty centers, primarily over drug turf, the victims and assailants usually people of color. Second on the list is the mix of alcohol and guns..everywhere.
Mass shootings in schools, supermarkets, etc, however? The majority take place in non poverty centers, the shooter invariably white.
For context:
The number of shooting deaths in the US in 2019? 14,000+
The number of pollution generated health deaths in 2014? 60,000+
An estimated ****** deaths were attributable to air pollution in the United States in 2021.
