“Peak” is a popular word these days—in particular when used before the word oil. But Peak Dirt? The concept refers to topsoil or, to be more specific, topsoil depletion. Earth, on average, is covered with about 3 feet of topsoil and this shallow skin of nutrient-rich matter sustains most of our food and plays a critical role in supporting life. “The estimate is that we are now losing about 1 percent of our topsoil every year to erosion, most of this caused by agriculture,” explains David Montgomery, a geologist at the University of Washington.
