Under the right (or is that wrong?) circumstances even oxygen,

And if one tries to live on good food, but of one kind only, health

It's all about the right amounts in the right measures and right
places. Correct?

Yes. Most educated people know that CO2 is essential for life on
earth. (It's what green plants take in.) The thing is to have just
enough, but not too much, of it.



People educated in government schools? I once had a respiratory
therapist tell me that CO was carbon dioxide. I could not get
her to understand that CO is carbon monoxide. I hope I don't
wind up in the hospital where she works.

I was educated in government schools and got a fine education. As were a huge
number of
Americans.

One idiot shouldn't condemn a whole system. By the way, what public school did
that person go to?
