Show Top Soil Our farms are Just as wide and just as long as they ever were, but are only two-thirds as thick and getting thinner every day. A third of our nation's topsoil has washed away. Topsoil is the basis of America's wealth and greatness. All of our food, clothing cloth-ing and shelter comes from the soil. When our iron, coal, oil and other natural resources are gone, we will have to devise substitutes sub-stitutes from products grown from the soil, because the soil is one natural resource that does not have to wear out or be used up. |
