I'm not talking about the climate or climate change, I'm talking about observable, scientific data that shows the air quality is unhealthy and even dangerous for humans.
And what good is a strong economy if your workforce is unhealthy or dead? Poor air quality leads to increased asthma and COPD, along with other respiratory conditions, cancers, and even things like skin conditions and mental illness. All of that is an extra burden on our healthcare system, which raises the prices, which means companies either have to pay more in insurance or the employee needs to contribute more, either way that's less money to go around for most people.
And to care more about wealth than the environment is short sighted since you need a sustainable, healthy environment to keep an economy moving.
