The Value of Biodiversity in Our Homes
Last Updated: Apr 13, 2025Today homeowners are incredibly concerned with the spread of germs and bacteria in our houses. However, what may surprise many is that each of our homes has a distinct microbial ecosystem. Our homes contain a more diverse population of microbes than what we find outside. Microbes, germs, fungi, good and bad bacteria - it is all present in our homes. In addition to preventing the unnecessary spreading of germs, it is also essential for homeowners to understand the importance of biodiversity in our homes. A community of microbes and their genes is called a microbiome.

We spend almost 90% of our time indoors. Consequently, the design and operation of the built environment can have a significant impact on our health. Since microbes are virtually everywhere, it is vital to learn about the microbes that are cohabitating our spaces.
Why Are Microbes Important, and What Do They Do?
Microbes, or microorganisms, are tiny living things that are found virtually everywhere yet cannot be seen with the naked eye. Microbes are a general term for fungi, bacteria, viruses, algae, and protozoa. They can be found on surfaces, in and on our bodies, and in the air, we breathe.
Although microbes are often associated with dirtiness, most microbes are incredibly beneficial. These microbes can be both advantageous and detrimental to our health, depending on their type. They are essential to life. In fact, a human body is made up of over 100 trillion microbes, both in and on the body.
Are Microbes Dangerous?
Mostly not, but sometimes. About 1% of microbes can cause diseases or allergic reactions. Current events will show you just how harmful microbes can be and how they can create worldwide pandemics. Coronavirus, chickenpox, measles, and malaria are all examples of harmful microbes. However, the majority of microbes are surprisingly good for you and your home.
What Is True of Microbes?
We Are Exposed to Hundreds of Thousands of Microbes Every Day
Our bodies, the outside environment, our homes, every surface we touch - all are full of good and bad microbes. Fear not, as is this normal and inevitable. The more diverse the microbiome, the higher the potential health benefits.
The Majority of Microbes Are Healthy for Us
Microbes can reduce the chances of allergies or autoimmune diseases, especially in small children. They can also fight against infections, help with digestion, and help to maintain your reproductive health. However, some microbes have the potential to be very harmful to our health.
