To avoid your confusion

Smog and GHG/AGW are different topics.

I agree with you about smog.

Don't agree that inert materials are not potentially pollutants.

"Do you agree, then, that what we should be doing instead is trying to limit the amount of smog and pollution that is emitted by industry?"

Yes totally!

Which is a separate issue from AGW, be it that they share some commonality.
