I was checking out the History Channel's Universe series when they started talking about Titan, and how it has an atmosphere 1.5X thicker than earth's, how it has rivers of Methane and Natural Gas (our new gas pump?). At any rate, figured I'd check out some articles across the internet to see what others had written about Titan and I come accross this very well written article that I've copied below. The article itself was fantastic but some of the responses this guy got was just absolutely HILARIOUS!
One of the posters said we should build windmills over there for energy. On a planet that a lake twice as large as Lake superior of pure Liquid Natural Gas! A planet where it rains methane, We should build inefficient windmills! Another poster claimed that we should leave Titan alone, as a nice preserve. Of course the fact that we're the ONLY creatures in the universe that we know of that can actually appreciate a preserve, this fact simply eluded him. Truth is, even if we did colonize Titan, we're talking about a moon that's 50% larger than our own, with half the gravity. Not a place we could necessarily put millions of people on.
Even if we could engineer a microbe that would eat the methane and exhale Oxygen (which is what many scientist thing happened on this planet), we'd still have to deal with the Nitrogen Cyanide in the Atmosphere, of which even tiny amounts could kill us. Either way, all attempts should be made to colonize other planets, just so we have a "Backup Place" to go to if we see a killer asteroid heading to earth.
Personally if I could somehow terraform these planets to make them habitable for humans, I would not care if it destroyed the Desolate Lifeless environments that are already there. Who cares, if this planet is destroyed, there would be no one left to appreciate any planets or moons that we've "preserved" for the future.
Here's the story.
