The two are linked how?

Are you seriously asking how polluted skies make people sick and trees make fresher air? Far out, I thought that was common knowledge.

Sorry I didn’t identify the picture correctly

It's ALL about pollution. I'm giving you the issue in its simplest form because a lot of people just don't understand.

You're connecting it with Greta Thunberg, the climate change poster girl. This has nothing to do with the climate. False equivalence. (If I didn't misunderstand the point, that is.)

What do you think causes this alleged climate change? Would it be emissions, pollution deforestation?
