TEDx Talks· 2025-12-22 17:11
All right, I want everyone to just take a moment. Um, take a moment and look down at your feet. I want you to picture what's below your feet and below that and below that and below that.And please stop before you come out on the other side of the world. What did you see. Dirt, roots, rocks, lava.Did anyone see a neatode. This horrifyingly adorable creature played a great part in the reason we are all alive right now. And I bet that most of you didn't know it existed and have been walking all over it your en ...
Practicing Sustainable Soil Renewal at the Altadena Community Garden | Erica Slater | TEDxAltadena
TEDx Talks· 2025-11-18 16:29
Environmental Impact & Remediation - Soil health is crucial for food production, water filtration, carbon capture, and ecosystem support; damaged soil puts communities at risk [1][2] - A fire in Altadena destroyed homes and the Altadena Community Garden, releasing toxins into the soil and devastating the community [3][4] - Micromediation, using mushrooms to clean the earth, is being employed to restore the soil by breaking down toxins into less harmful organic material [6][8][9] - Mycelium, the root network of mushrooms, transforms toxins into food for the soil, acting as a natural cleaning system [7][8][9] - Micromediation has been used to clean up oil spills, heavy metals, and microplastics, and is being experimented with in fire remediations [9] Community & Restoration Efforts - The Altadena Community Garden is being restored through community involvement, including gardeners, volunteers, and partners [10][11] - The community is working to restore the health of the soil, hoping that mycelium will remove contaminants and allow new plants to grow [11] - The Altadena Community Garden was originally established 50 years ago on barren land through community cooperation and a belief in the power of growing food together [13][14][15] - The community is experimenting with micromediation and plans to share their findings to help restore soil health in Altadena [16][17] - The goal is to create a healthier and more resilient future for Altadena through community, cooperation, and creative experimentation [16][18]
Humus - the basis of life | Franz Rösl | TEDxOTHRegensburg

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]
The answer is soil | Chris Huskins | TEDxWinchester
TEDx Talks· 2025-07-01 16:58
Environmental Concerns & Challenges - Soil depletion poses a significant threat, potentially rendering soils unable to grow food within 60 years [1] - Conventional agricultural practices, including plowing and chemical use, degrade soil health, leading to dust storms, floods, and rising food prices [2][5] - Degraded soils lose their capacity to hold water and store carbon, exacerbating climate change and food insecurity [5] - Over the past 70 years, the nutritional content of fruits and vegetables has decreased significantly due to soil degradation [6] Solutions & Regenerative Practices - Healthy soil, teeming with microorganisms, can sequester carbon, filter water, and provide essential nutrients for food production [4][5] - Regenerative agriculture practices, such as no-till farming, cover cropping, and livestock integration, can restore soil health and ecosystem function [10] - Gabe Brown's farm serves as a successful example of how regenerative practices can revitalize degraded land and enhance resilience to extreme weather [11] - Beavers can act as natural water engineers, creating wetlands that boost biodiversity and replenish soil [13][14] Call to Action - Supporting farmers who employ regenerative or organic practices is crucial for promoting soil restoration [17] - Governments should prioritize funding soil restoration initiatives over destructive agricultural practices [17] - Recognizing soil as the foundation of life and educating future generations about its importance is essential for ensuring a sustainable future [18]
