The war on faith.

[Matt R.]

(pure guess)

Yes, I do. I'm not "traditionally" religious, but I'm definitely religious to a significant extent, and I definitely care about the continued existence of earth.

A religious person may rationalize that it doesn't matter what happens on earth because ultimately, he/she will be in heaven. But, an atheist can rationalize not caring about what happens because, ultimately, the sun will burn out and the universe will die a slow heat death. Thus, he/she may as well maximize pleasure at the expense of a healthy Earth since no matter what occurs in the interim, the ultimate destination is non-existence (for both the person and the universe in its current form).

So yeah, I really have no idea. But I can see equally valid arguments going both ways as to why a religious person vs. a non-religious person "don't care" about the continued existence of earth and life. If they aren't exactly equal in "caring", I would guess that they are extremely close -- I've never met a religious person that legitimately doesn't care about the current situation on Earth because he thinks he's going to heaven.
