Hey Raverguy? Be different than everybody else please? Just once, get an idea in your head and type it into google. You know, do a little independant research? Now, nothing against you because this is typical behavior on a website. People should be motivated to find the truth and not just ask for it to be spoon fed to them.
Now, I typed in percentage of carbon dioxide into this magical thing called GOOGLE...

A request to all of you... Before you scream for a link could you at least take the time to type google and the subject into your browsers? That way you get independent verification of the information you are reading...
