Soil and human security in the 21st century
... Human security has and will continue to rely on Earth’s diverse soil resources. Yet we have now exploited the planet’s most productive soils. Soil erosion greatly exceeds rates of production in many agricultural regions. Nitrogen produced by fossil fuel and geological reservoirs of other fertilizers ...
