A terrifying article about the next United States dustbowl:
From the article:
The UCS study analyzed various scenarios for erosion rates and total soil loss using soil survey data from the National Resources Inventory, a research program conducted by the USDA and Iowa State University. Because of climate change, the possibility for even more accelerated erosion rates exists. The study found if more flooding and droughts lead erosion rates to worsen again, reverting back to the higher rates recorded almost forty years ago, farmers nationally are at risk of losing more than two inches of soil by 2035 and five inches by 2100.
In other words, we depend on the soil to grow the food we eat, but we are not good stewards of the soil. Therefore the topsoil is washing and blowing away, and with it our ability to grow grains like wheat, corn and soybeans. It could lead to a food catastrophe.
