The kid is my older daughter, I'll let her know she has a creepy voice!!
Seroiusly though, it's meant to be a bit spooky, I rekon the music box helps the effect too.
It's our generation which has made these problems which are going to affect her generation and beyond, what if children were aware of the issues threatening the environment and were able to orate their opinion eloquantly?
I used a child voice to enforce the point, if it was a mature voice reading the words, it would appear to be just another public service announcement and people would probably just drift off but, in my opinion, the "creepy" kids voice draws your attention and makes you listen to the words.
Steve, looking forward to the mail.
