Why?

Strolling through the deep, dark bundle of trees,
I can hear the birds calling for me,
But there's also the sound of a swinging axe,
Slicing the tree as I hear it all.

I follow the sound of the axe, 
There they are, humans with axes and chainsaws,
Cutting through the trees, finding things they need,
I see a squirrel running from the cut trees.

That tree is its home,
So I yell "STOP!"
They all look at me confused,
Then I yell "STOP!" again.

They all run away, scared?
But now the squirrel's home is saved,
The frightened squirrel returns,
It gives me a happy face, like it's thanking me.

My frown turns into a smile,
So I continue with my stroll through the now bright woods,
As the birds return to singing.
