I have heard the story once that O2 is highly toxic to life if it were taken too much or in highly densely form, but because it exist with a combination of nitrogen in the rate of 1:4, it is beneficial to life.

Actually what's really toxic is the partial pressure of O2. This is the reason why divers can't dive below 85 feet (If I recall correctly) on Nitrox II. It's also the reason why pilots need pressure suits and full face masks even if they're breathing pure oxygen above Flight Level 350 or so. If you can't get the ambient air to a pressure of at least 20 percent of an atmosphere, then you'll slowly go hypoxic as your body attempts to breath in sufficient oxygen.

Thank you for finding my comment. I wanted to make a comment this directly to the article, though, I felt it slightly off topic, so I posted here. Seemed nobody's reading my journal, your comment encourages me much.--
