Microbiome Crisis: The Invisible Biodiversity Battle Inside Us
10 Nov
Summary
- Microbiome loss linked to health issues, described as "internal climate crisis"
- Simple steps like gardening and kissing can boost microbial diversity
- Finland leading the way with rewilding kindergartens to expose kids to microbes
As of November 10th, 2025, a growing body of research is highlighting the importance of preserving the human microbiome - the trillions of bacteria, fungi, and viruses that live within our bodies. Experts now describe the loss of this internal biodiversity as an "internal climate crisis", with urbanization, processed foods, and overuse of antibiotics contributing to the problem.
Just like we need to protect ecosystems in nature, we must also safeguard the microscopic worlds within our own bodies. Researchers say simple steps like gardening, spending time in nature, and even kissing can help boost microbial diversity and improve overall health. Finland is leading the way with a program that's rewilding kindergarten playgrounds to expose children to beneficial microorganisms from an early age.
While the idea of microbes covering our bodies may sound unnerving, these invisible ecosystems play a crucial role in keeping us healthy. From wound healing to immune function, the microbiome is now recognized as a key factor in human wellbeing. As the science behind this field gains credibility, more people are realizing the importance of nurturing the biodiversity within.
