HI Diana!
whew! I thought I was missing a few screws, I tried the first link you gave, and I wasn't able to reach the site, I finally clicked another link that was posted in this thread from MSN HERE,
http://www.msnbc.msn.com/id/11736311/
but they did not mention anything about Oxygen in that article just Methane and CO2 and Carbon.
thank you for clearing that up for me, it was driving me crazy!
LOL,
Dennis
