Conservation of Soil Fertility

I believe that the most important aspect of the biological world to conserve would be soil fertility. The fertility of the world’s soil is an essential component of the biological world for both humans and other mammalian species. Soil itself is where carbon, nitrogen, phosphorus and many other nutrients are stored, transformed and cycled. All these nutrients are necessary for life on earth.  Soil erosion and degradation has been one of the most pressing issues facing human security in the 21st century. As the global population continues to increase our long term viability of farm land slowly begins to decline. Farming practices being shifted through the years has caused an accelerated loss of soil and this serious decline of fertile soil is threatening food supplies.
