According to the Food and Agriculture Organization of the United Nations (FAO), one-third of the planet’s soils are degraded. This condition is caused by a number of natural factors, including wind and water erosion and nutrient imbalances, but people also leave an indelible impact on the earth. About 38 percent of the worlds’ surface is dedicated to agriculture to feed a population of 7.2 billion. That population is projected to increase to over 9 billion by 2050.
