The world may be running out of usable topsoil, the layer that allows plants to grow. According to an article that suggest we have only about 60 remaining years of topsoil. Around 40% of the world’s agricultural soil is now classified as either degraded or seriously degraded; the latter means that 70 percent of the topsoil is gone.
Our top soil is being lost at 10 to 40 times the rate it can be replenished, and our food production systems are to blame, which epitomizes the term “unsustainable.” It takes decades or even centuries to regenerate significant levels of soil.
