The earth currently has approximately 6 trillion tons of top soil suitable for agriculture, down from estimated 10 trillion tons in 1970. Erosion caused by human activity continue to remove approximately 1.5% of the 6 trillion tons each year. The removed top soil mostly wash down rivers and end up at the bottom of the sea.
Unlike proven oil reserves, which increases every year as more exploration uncovers more oil, there is little prospect of significant discovery of new previously unknown topsoil reserves.
