The air we breathe is sweet and clear
Used every day of every year
Pure and fresh, up to the sky
Expanding out, forever high

Nourished by Earth's plants and meat
Depending on the food we eat
To keep us strong, and keep us fit
Our lives, indeed require it

Water runs from mountain brooks
Seeping out from rocks and nooks
Trickling, bubbling, Nature's spout
Refreshing us, inside and out

Necessities to stay alive
We need them, crave them to survive
All the creatures, flowers, trees
Require elements, as these

If one small peice was pulled away
The world would surely die that day
But, trust me, Love, this much is true;
I'd sooner perish without you
