The effect of soil degradation on human, animal and plant health Soil degradation is the biological, physical, chemical, and biological decline of soil quality or health. This phenomenon is problematic because it reduces the capacity of soils to support plant and animal life. Additionally, it reduces the ability of soils to regulate essential ecosystem services such as water regulation and nutrient cycling. Soil degradation has become a global issue and has come about largely due to land conversion from forests and grasslands to intensive agricultural practices. Land conversion depletes soil organic matter values, releasing large amounts of carbon dioxide into the atmosphere, contributing to global climate change and reducing soil fertility and soil health. Dr. Christine Sprunger, soil scientist and ecologist at W.K. Kellogg Biological Station (KBS) and the Department of Plant, Soil, and Microbial Sciences at Michigan State University, discusses the danger of soil degradation on human and animal life, and what we can do to mitigate it.
