why isn't the sky as blue as it used to be ? it seems that when I was a kid the sky used to be blue now its light light blue
It's turning brownish grey from nasty all up in the air.
Lol, pollution maybe? :P
Perhaps your eyes are not what they were back in the day.
If you moved to a new place it can change the way the sky looks. For example if you live by the ocean the sky is blueer because it's reflecting off the ocean.
