We are just barely beginning to investigate the harms from PM2.5 particles.
It seems like every month we discover some new and harmful effect, or that it was worse than initially estimated from smaller sample sizes, etc.
I don't think it's a conspiracy, just the way that discovery happens.
We also have a tendency to completely oversight the harm of new tech in comparison to older tech. People get super worked up about the supposedly super toxic lithium ion batteries, but have little concern for the far greater amount of mining necessary to build the frame of a car.
So it's good to have a baseline of the amount of harm done with current tech to compare to and center our reactions to these large population scale effects.
