Grampa says, so it must be true
The seas and oceans once were blue,
Grampa says that lakes were seen
All crystal clear, not gooey green.

Grampa says when he was small
They'd winter, summer, spring and fall.
Grampa says they used to eat
'Fruit' and 'vegetables' and 'meat'.

Grampa says that in his day
Folk rode in 'cars' on a 'motorway'.
Grampa says that till Earth browned,
People lived above the ground.

Grampa says, and I don't doubt
He knows what he is on about,
Grampa says there used to be
A living thing they called a 'tree'.

Grampa says that since his birth
We've swiftly trashed our mother Earth
Grampa says it's in the stars
That next we'll take our trash to Mars.
