Very pretty - so aliens regards us glow worms in a cave. That's not what I
would call a purposeful and intelligent change to the environment.

Riddle me this...

1. Is it likely that eventually our atmosphere would be significantly
affected by world-wide industry pumping out mega tons of pollution every
day?

2. If "yes", is it plausible that now is the time that the
atmosphere is starting to notice us? (Is a century long enough?)

3. Is it likely that a change will be good or bad with regard to its
effects on current life?
