supermansion-earth-day-special-song

I took a stroll

To see nature and its trees

supermansion-earth-day-special-song

But what I saw I couldn’t unsee

There was litter everywhere

supermansion-earth-day-special-song

And an oil covered bear

The buzz of saws

supermansion-earth-day-special-song

Turning ancient oaks

Into lawn chairs

I heard a sound

In the rustling of the leaves

It made me wish

That we could talk to the trees

If trees could talk

What would they tell us?

Climb up our trunks

Give us a big ol’ hug

And please don’t fell us…

They are not just pencils,

Paper and hot tub decks

They put O2 in the atmosphere

Let them bend your ear

(Everybody!)

They’d say they love us

(They’d say they love us)

So let’s stop killing

Every tree in sight

And let them hug us
