Humus - the basis of life | Franz Rösl | TEDxOTHRegensburg
TEDx Talks· 2025-09-22 16:39
Soil Health and Human Health - The quality of the soil directly reflects human health, as humans are a reflection of the earth that provides food [2] - Plants transform the earth into a form that humans can incorporate into their bodies, highlighting the importance of plant-soil interaction [1][2] - Soil is a living organism with the ability to regulate and heal itself, functioning like an organism through symbiotic processes [5] - Symbiosis between plants and microorganisms is crucial for nutrient supply and protection from predators [6][7] - Healthy soil can absorb up to 100 liters of water per square meter, preventing flooding and soil erosion [13] Impact of Agricultural Practices - Pesticide use destroys symbiosis between plants and other organisms, causing permanent damage to soil life and affecting plant health [8] - Force-feeding plants with liquid manure or synthetic fertilizers disrupts symbiosis, leading to sick plants and potentially sick people [10] - Soil compaction from heavy machinery hinders plant root growth, making them less resistant to stress and reducing yield [16][17] Soil Management and Sustainability - Humus is a result of symbiotic processes and is a very important part of the soil; conditions should be created to promote its buildup [7][8] - Loss of humus through erosion leads to higher loss of soil fertility, with 1 cm of humus soil taking 100 years to form [14] - Maintaining biodiversity in fields makes the use of pesticides unnecessary, promoting plant health and disease resistance [11][12] - Healthy soil promotes the quality of drinking water and groundwater recharge through active microorganisms that purify water [15][16] Interconnectedness of Life - Everything is connected in symbiosis, emphasizing that health is based on a symbiotic environment and peace [18][19]

[Music] [Applause] So my background is in computational neuroscience and applied math. Um I went to Google uh about 12 years ago and uh my my first number of years that that I was working there. The the main project was to add AI features to Android and Pixel phones.So uh most of the AI uh in in those phones uh over those years came from uh teams that I built. Uh some of these features are things like uh face unlocking and um music recognition. This feature called now playing.Uh we built um predictors of ne ...

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]
