As usual: Treat the symptoms, not the cause.

Or… Drive fewer cars and run fewer gas motors!!!

“We just set off fireworks for a holiday, for an entire day! Why is there so much smoke pollution?!? Maybe we should start seeding the clouds, because there’s nothing else that we can do…”

Pollution controls, dumbasses. Hey, and maybe some incentives not to extremely overpopulate? Maybe some free condoms or something? Only people pollute.
