Nature's beauty
From the tallest peak to the smallest flea
In every leaf and every tree
Nature's wonder never ceases to be

The mountains high and rivers blue
The animals that roam so true
The sun that warms and skies of hue
Nature's magic always shines through

The breeze that blows and waves that crash
The fireflies that in summer flash
The thunderous storms and lightning's flash
Nature's power will always last

So let us preserve and appreciate
The beauty of nature, it's never too late
For it's a treasure we can't recreate
A reminder of life's precious fate
