With all due respect, I'd like to point out the following. We (the earth) are ONE planet. According to ScienceBlogs dot com, our Galaxy (The Milky Way) has roughly 250 trillion planets within it, and according to Space dot com, there are at least 100 billion galaxies in the Universe. Lets say that The Milky Way, at 250 trillion planets, is an average-sized-galaxy. That would mean that our entire Universe could contain as many as 25,000,000,000,000,000,000,000,000 planets within it (all galaxies combined). This is probably a conservative estimation, and that there could be as many as twice that number.
Scientist believe that at least 60-70 billion planets per galaxy can sustain life (x 100 billion galaxies) and assuming that He needs to visit them all, it could be quite a while before his Kingdom actually gets here, depending on where we are in the queue. My point is, we may not want to wait that long and so should maybe take it upon ourselves to take care of some of that "wicked" stuff.....you know, like contributing to global warming.

just saying....
