Protection of the World's Topsoil

The protection of the worlds topsoil is vital to us. The soil is still the major medium for plant and crop growth and our basic resource for land use and development. Imagine our world without soil! A barren land with almost no plant growth and constant dustbowls to block out our sunlight. Erosion would destroy our mountain ranges. Our lakes, rivers and oceans would be clogged with sediments. Like any of our worlds problems, we must educate people about the problems and risks and how the depletion of topsoil affects our everyday needs. (Kirby, 1997)

Protection of the Worlds Topsoil

THE "BIG THREE"

There are many reasons why our soils become damaged. The three biggest contributors are: erosion, deforestation and overgrazing. Erosion can be the most damaging of all three because we cannot control the weather. Erosion exists when either water or wind removes important soil particles from the earth leaving the land useless for growth. AS Vice President Al Gore states in his book, Earth in the Balance, "Iowa has lost eight inches of the best topsoil in the country and it now resides in the Gulf of Mexico" (1992). Although we cannot control Mother Nature, we can combat erosion by insuring plant or crop growth is present to naturally to dissipate the effects of erosion. If not properly managed, the damaging effects of erosion can alter out lives both socially and economically.

The second of the contributors is called deforestation. Deforestation is simply the clearing of forests to support our demands for lumber, paper products, and fuels. Without proper management of this activity, the soils are susceptible to erosion...
