For every one acre of land lost to shopping centers, houses, roads, and other
developments, 7 acres are lost for feedlots and feed cropland.4
This loss of forest land leads to topsoil erosion (there are no trees to
keep the topsoil in place).
This year, in the United States, we will lose 17 billion tons of
topsoil to erosion.4
The overgrazing of deforested land is a major cause of desertification.
