The Symbiotic Self | Dylan Orsolini | TEDxWCC

Biological Composition & Symbiosis - The human body is composed of approximately 30 trillion human cells and 39 trillion microbial cells, indicating humans are outnumbered by microbes within their own bodies [1] - Symbiosis, or cooperation, is a fundamental aspect of biology, as important as competition in evolution [3] - Mitochondria, essential for eukaryotic life, evolved from bacteria through a symbiotic relationship [4] - Microbes in the digestive tract aid in breaking down indigestible foods and enhancing nutrient absorption [5][6] - E coli on the skin protect against harmful pathogens by providing a barrier against invaders [7] Genetic Diversity & Microbiome Impact - The human genome contains approximately 22,000 protein-coding genes, a surprisingly low number compared to other organisms [8] - Human biodiversity is significantly influenced by the microbiome, which shapes individual experiences throughout life [9][10] Ecological Perspective - Viewing the human body as a collective of organisms highlights the importance of balance and strength within this ecosystem [10] - Humans, like microbes on the planet's skin, have a responsibility to protect and preserve the Earth as a superorganism [11]
