Breathe in, breathe out
We're still alive because o2's throughout
Air due to plants and algae

Water, light, and a breath
Is all it takes for plants to make
Their food and the air that we breathe

From lowly grass to lofty trees
All plants on earth hold the key
To all we eat, and all we breathe
The source of all our energy

Not all that we have
On this earth is what meets the eye
Because all that's green keeps us alive
