After a birthday party I would always go outside and accidently lose my balloon and let it drift off into the sky, but now I know to never take a balloon outside because if it floats away I am sad and it could end up in a turtles stomach.
I used to think that if I put something in the bin it would magically vanish, but now I know that it can take over 100 years to break down.
I used to think chopping a dead tree was okay, but now I know it is a habitat for the animals.
I used to think that if I was drawing and messed up it was fine to start over on a fresh piece of paper, but now I know that it is killing the trees.
I used to squish little bugs all the time, but now I know that you should never do that because it is murder and you are destroying the food chain.
