A single cell, so small and round
In a world of microbes, I am profound
I reproduce quickly, with no need for mates
I adapt and evolve, it’s simply my fate
I can be helpful, or cause harm and pain
I exist in every place, from soil to the vein
I am a bacterium, and this is my story
A never-ending journey, without any worry
I may be tiny, but I am mighty and strong
I have survived for ages, and I will live on
Through the ages I’ve been, and I will always be
A tiny, yet powerful, part of this world’s history.
