Dave, I did read the NASA link you posted. It's timely, considering the Curiosity rover (aka Mars Science Lab) is due to land on 5 Aug. It should provide alot more information about whether biological processes have played a role on Mars. I look forward to reading more.....NASA missions tend to get alot of front-page coverage in the local news for some reason. But I don't see any thing sinester or threatening in what the MSL finds, or anything that could affect the need to protect and conserve our scarce resources on Earth. Can you explain why it's so significant to you that the methane on Mars (and other planets) was apparently created via geological processes (as well as some small portion of the methane on Earth)? And what's not polically correct about acknowledging this fact? I've got no problem with it at all, and I've already said I'm an environmentalist. Are you saying that since inorganic processes can create methane, there is no need to conserve it? Or that there is a virtually unlimited supply of methane on other planets, so that all we need to do is find a way to go get it? Note, I'm not interested in changing your thinking, just curious about what it is. Just can't understand why it would be so important to know how the oil and natural gas we consume was created all those eons ago. Perhaps you think there is some kind of conspriracy by "big oil" to make it appear that the world's supply of oil will run out in 43 years (or 100 years, pick your own number).
