the other option is to act like we have only one planet to live on, but it sounds like you'd rather just omit the impacts from the industrial revolution on the atmospheric since, you know, it's such a small fraction of earth time. before commenting on this topic, at least do some research on carbon footprints, etc. also, no kleenex needed...i actually don't even like the cold (though i do love snow, go figure). i do, however, have more faith in the people who study this topic for a living and do have concerns on what the longterm impacts of global warming could be. wish more people would at least entertain the idea that it matters.
