Yes and no. Carbon dioxide's common name is carbonic acid and it is indeed acidic though a gas. Foliage can deal with it as a gas. When rain falls through it, it becomes dissolved and becomes the liquid form of carbonic acid and becomes known as "acid rain".
As long as there's carbon dioxide, there will always be, at the least, a weak, dilute "acid rain" falling. It becomes an issue when the concentration is high due to high levels of carbon dioxide in the atmosphere...so you see, a lot of carbon dioxide, combined with massive forest clearing (as foliage processes carbon dioxide), the concentrate of carbonic acid becomes more problematic.
The goal isn't so much as to control all sources of carbon dioxide as it is to control the portions of carbon dioxide generation that we CAN control.
