About Perspectograph
We may like to think humans rule the planet, but microbes far outnumber us. Around a nonillion (10³⁰) microbial cells live on Earth—more than the estimated number of stars in the observable universe. They are everywhere: in the soil beneath our feet, in oceans and the atmosphere, and even inside our own bodies.
They are also some of Earth’s oldest residents. For billions of years, microbes have survived, adapted and thrived in places most life forms could never endure—from deep ocean sediments and hot springs to polar ice.
But microbes do far more than survive. They recycle nutrients, support ecosystems, and help drive the processes that make life on Earth possible. Today, we are also finding ways to use their abilities in agriculture, biotechnology, energy production, and environmental cleanup.
Perspectograph explores this largely unseen world: how microbes live, the vital roles they play in nature and the surprising ways we are learning to work with them. Like the Cosmic Turtle, they represent balance, endurance, and the quiet forces that keep the world going.
About the Author
Dr. G.O. Sanni studied Microbiology at Obafemi Awolowo University in Ile-Ife, Nigeria, where she earned her Bachelor’s and Master’s degrees. She later completed a PhD in Environmental Microbiology at the University of Essex, UK, specialising in the microbial ecology of oil-polluted marine environments. After moving to Canada, she obtained a Certificate in Applied Clinical Research from McMaster University in Ontario.
Outside science, she has always enjoyed reading, writing, and exploring a wide range of subjects. She also enjoys graphic design and runs a YouTube channel where she shares some of her creative and educational projects.
Her interests in microbes, storytelling, and visual design came together in an illustrated science book for young readers, which remains unpublished. She is also the author of Wrathenville, a gothic supernatural horror novel published in 2025.
She lives in Calgary, Canada, with her family.
