Fair enough. I think the difference is that any issue that falls into the "save humanity" category, such as colonizing other planets, or saving the earth from global warming, do not feel urgent for me, because of my perspective. For the Earth to be uninhabitable due to global warming would mean that it could no longer serve its intended purpose, and thus God would wrap things up before that point in time. Now it's perfectly fair to ask "What if you're wrong?" I don't believe I am, but I am willing to do my best to take care of the Earth the best I can. It is after all God's beautiful creation, under our stewardship. But I have to balance that with many other things that may be more important. For example, having a strong economy with the help of fossil fuel, so that families can support having children, etc...
