Why?

Why do trees grow?
When you can cut them down.
Why do people swim?
When they can easily drown.
Why is the sky blue?
When we pollute it so much.
Why does the blind read?
When all they can do is touch.
Why is the grass green?
When all we do is litter.
Why does a husband still love his wife?
When all he does is hit her.
Why is it we can't choose,
When we want to die?
Because God put us on this earth,
To keep us asking, Why?
