The next threat is passive breathing. I inhale air and remove the oxygen, replacing it with carbon dioxide. You have to breathe my used carbon dioxide.

This would not be so terrible EXCEPT that winds blow from West to East (usually). Therefore everyone in England, for example, getting less oxygen because all of their air has been depleted of oxygen by Americans and Canadians (Mexico, Central and South American are in too low a latitude to affect the UK, but they DO affect other places).

The UK is suffering from anoxia, and I for one REFUSE to give up breathing just because some Limeys are gasping for breath! I have enough trouble with the halitosis that wafts into Idaho from Portland and Seattle!
