It's unfortunate. Not just because of the lost beauty. But I think it contributes ever so slightly to the relentlessly increasing narcism of modern youth. When you seen the enormity of the galaxy spread out in front of you, it's hard (for me, anyway) to not be reminded of the puny insignificance of one's problems. On the properly appreciated scale, your entire existence is so utterly inconsequential that it really doesn't make sense to get too worried about things. As A.E. Housman put it:
Life, to be sure, is nothing much to lose,
But young men think it is, and we were young.
