  2. Soil biodiversity - Wikipedia

    en.wikipedia.org/wiki/Soil_biodiversity

    Soil structure is essential to soil health and fertility; soil structure decline has a direct effect on soil and surface food chain and biodiversity as a consequence. Continued crop cultivation eventually results in significant changes within the soil, such as its nutrient status, pH balance, organic matter content, and physical characteristics ...

  3. Soil health - Wikipedia

    en.wikipedia.org/wiki/Soil_health

    Soil health testing is pursued as an assessment of this status [1] but tends to be confined largely to agronomic objectives. Soil health depends on soil biodiversity (with a robust soil biota), and it can be improved via soil management, especially by care to keep protective living covers on the soil and by natural (carbon-containing) soil ...

  4. Biodiversity hypothesis of health - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_hypothesis_of...

    According to the biodiversity hypothesis, reduced contact of people with natural environment and biodiversity may adversely affect the human commensal microbiota and its immunomodulatory capacity. The hypothesis is based on the observation that two dominant socio-ecological trends – the loss of biodiversity and increasing incidence of ...

  5. Environmental health - Wikipedia

    en.wikipedia.org/wiki/Environmental_health

    Environmental health is the branch of public health concerned with all aspects of the natural and built environment affecting human health. To effectively control factors that may affect health, the requirements that must be met to create a healthy environment must be determined. [ 1 ]

  6. Soil ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.

  7. Soil biology - Wikipedia

    en.wikipedia.org/wiki/Soil_biology

    The soil is home to a large proportion of the world's biodiversity.The links between soil organisms and soil functions are complex. The interconnectedness and complexity of this soil 'food web' means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil.

  8. Environmental protection - Wikipedia

    en.wikipedia.org/wiki/Environmental_protection

    Since 1970, the United States Environmental Protection Agency (EPA) has been working to protect the environment and human health. [65] The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters.

  9. Soil functions - Wikipedia

    en.wikipedia.org/wiki/Soil_functions

    Soil provides raw materials for human use and impacts human health directly. The composition of human food reflects the nature of the soil in which it was grown. An example of soil as a source of raw material can be found in ancient ceramic production. The Maya ceramics showed traits inherited from soils and sediments used as raw material. [8]
