Answer:
The more you take away from me, the bigger I shall get. What am I?
You can read me both ways I wear; One way it's a number reversed a snare.
I am an instrument capable of making numerous sound but cannot be touched or seen.
I direct you from outer space.
There's not a kingdom on the earth I haven't traveled over and over and though I know not whence my birth yet when I come you know my roar. I through the town do take my flight and through the fields and meadows green and whether it be day or night I neither am nor can be seen.
In birth I spring forth, in life I unfold. In death I wilt and die, but rebirth restores all.
