Beautifully sung at many Plum Village retreats by Francoise Pottier.

This is the Earth (or any noun: water, people, etc.)
Celebrate the Earth (same noun)
May you always have (or any verb: drink, etc.) your fill
We can save the treasure if we work (or any verb: stick, hang, etc.) together
And celebrate the Earth (same noun).

Don't think we don't need you; we need you.
Don't think we don't hear you; we hear you.
Those who care just lift your voice and join us as we sing.
Save our planet, keep our planet green.
