That is ture. Earths atmosphere will eventually disipate.

If one really thinks about it, how long do you really think we would last on this planet the way things are going now? Environment and Pollution is one thing, greed, resources, war hatred are other things. Unless we "see the light" and change our ways, earth won't last another 500 years in my opinion. That doesn't mean that we can't go other places...but Earth is our home. Its a shame the way we treat it.
