Summary
Diversity in ecology and genetics appears to be a very good thing. The human species has a genetic pool (all the genes variants from all the humans alive) that is diverse and protective for our species. Human bodies and all other multi-cellular organisms host diverse arrays of micro-organisms that our essential to health.
Morbidity and Mortality
Antibiotics, pesticide, cesarean sections, baby formula, monocrops, processed foods, disconnection with nature, other pharmaceuticals like proton-pump inhibitors, and other factors have all contributed to a mass extinction of the human gut microbiome. It is estimated that humans have lost 50% of our microbial diversity in the last few hundred years.
Story
Microbial fossils isolated from 1000 old poop shows 38% novel species (now extinct)
Key Points
1. Humans bodies are an ecosystem
2. A diverse ecosystem is associated with health. Dysbiosis is associated with numerous chronic diseases.
3. The food we eat and the way we live our lives has profound effects on our microbiotia and health.
