No way it is all liberal media hype.

I suppose you mean "Do we need *clean* air to live?" because common sense tells us that suffocation is not a good thing for your health. Of course we need clean air; people in cities with heavier air pollution such as Beijing and LA tend to get more respiratory infections. Also, polluted air causes acid rain, which burns leaves off trees...leading to deforestation and eventual desertification. The media might blow certain ecological problems up (like in The Day After Tomorrow) but this is a real issue.

Not technically. Air is mostly nitrogen gas which humans don't use. We use the oxygen (about 16% of air) and plants use the carbon dioxide (about 2-3%).
The other thing to consider is, no air means no air pressure (like barometric pressure) so our environment would be pretty much exactly like the surface of the moon. All our water would evaporate, there would be no weather, and since there would be absolutely no greenhouse effect it would also be very, very, very cold.
cheers.

it is not so much air that we need because air is made up of many things like oxygen, nitrogen, helium, and many other gases. but we do need a lot of what is in the air to stay alive. like oxygen, carbon, and it may seem like we dont use it but nitrogen aswell. we breath in and breath out the same amount of nitrogen but that is not to say that we dont use it because we do. just look it up on google or something. but be careful because not everything you hear there is true.

Nope don't need air... just oxygen... problem is, I am not aware of another safe way to get oxygen into my blood system other than by breathing air.

Obviously...Air has oxygen which our bodies need to survive. Hold your breath and see if you want air after a while.

No. We only need zest from a lemon and 3 drops of cat piss and we're good.

Maybe if your will were strong enough you would not need air to live.
