I think it’s better if you make the location and victim rate specific in that case. For me, I live in a developing country in which pretty much every household have at least one motor vehicle, and the air pollution in bigger cities (especially the capital) is basically notorious. So when most people are told to work from home, there’s definitely a change in pollution rate, that is of course in affected areas.
Excessive household garbage would lead to more pollution because of waste processing, is that what you meant? I’m not quite sure about this then again I don’t know much about waste disposal anyway and from where I live, they usually just get thrown away and some get recycled.
