What human activity is responsible for the formation of smog and acid rain?

The burning of fossil fuels can cause smog and acid rain.

The answer to this question is very simple! I think that the activity humans are responsible for that causes acid rain and smog is pollution of engines giving off waste. Acid rain mostly takes place in the cities such as new York or Las Angeles! I had a teacher who once told us about the problems with acid rain in new York he had said it was impossible to wash off cars once it was attached which normally leads to the car rusting and falling apart!
