Today you are going camping
With your family, friends or class.
Please help us, dont drop any litter!
Because your litter lives longer than us!

Refrain: Because nothing is forever
And nature is getting tired.
If we dont stop and think today
Tomorrow the Earth could die.

Refrain

Today you cut down your forests
But the planet needs our leaves.
Please stop it because tomorrow
You will have no air to breathe.

Refrain

You can have a bath or a shower
But today is the time to think.
Save the rivers because without them
You will have no water to drink.

Refrain

Today we are still in your forests,
In the sky, in the rivers, but look:
Dont kill us! Because your children
Will see us in picture books.
