Now we know who's causing global warming

I really don't know what to make of today's strip. I feel bad trying to say anything bad about it, because pollution is bad, mmmkay? But it's just so bizarre. Isn't smoking pretty much already prohibited in all workplaces already? I've encountered a few places (like my old job, for example) where there was a smoking lounge, but most places don't have anything like that anymore, much less allow people to light up at their desks. Or assembly line station. And would a boss try to ban it because it pollutes? Most people ban it for, you know, health reasons. Not that air quality doesn't affect our health, obviously, but I've never heard of this sort of correlation.

Man, I just hope Honcho is doing something about that pollution from his factory. Honest, guys, I just don't know what to say here. Well, except that "diffo" is just wrong. As is the hyphen between "cigarette" and "smoking." (And does that mean that pipes and cigars are A-OK?) And also, use different words in the expo box and how people are coughing. That's just lazy.
