What has happened to the air we breathe everyday?

Question

I always wondered could anyone help a gal out!

Answer 1

its still there, its just polluted.

Answer 2

The big difference if you live in the US, is the air is cleaner.  The air quality overall has improved since the 1970's.  A lot of what you here in the press about non-attainment is because the air standards have been lowered, which is a good thing, we should all try to have the cleanest environment as possible, it's just that people get the wrong idea, and don't realize that we are making real progress.

Answer 3

we breath it out as carbon dioxide then trees produce more oxygen

Answer 4

Absolutely nothing.  It's the same as it has been.  Oh yeah, global warming and the big pollution deal is BS just so you know...Really
