Desertification: What Is It?
Author : Shawn Wilson
If you’re interested in environmental or green issues, you probably know all about things like sustainable design and energy conservation You have a decent understanding of the effects man’s actions can have on the planet, including issues like deforestation and global warming But you may not know about one very important effect of the deforestation currently spreading all over the globe: desertification
Desertification is one of the first truly visible consequences of the effects of man’s disregard for the health of the planet; many consider it to be a sign of what our children and our children’s children will soon come to face
But what is it? Desertification is the name given to the process which turns a normal, healthy ecosystem into a desert– a desert that wouldn’t have appeared if nature were allowed to take her natural course The term doesn’t include the natural deserts that have existed for thousands of years Natural deserts develop over time due to a low amount of rainfall or a difficult climate, making a particular swath of land unable to support animal or vegetable life easily The “artificial” deserts included in the term desertification are unintentionally created by man
Desertification is the result of one or several man-caused events, including acid rain (which results from manmade pollution), the overgrazing of cattle, intentional and unintentional manmade fires, and, of course, the cutting of trees for the production of paper products and for wood
What Happens During Desertification
In some areas, only one of the above factors might come into play to encourage desertification In other areas, you may see a combination of all four When a piece of land has been sufficiently affected by man in order for the desertification process to start, the land slowly transforms from a rich habitat into an unnatural and often completely uninhabitable desert
In an unnatural desert, different species of animal life living in the area begin to die The local plants disappear gradually– or sometimes all at once When the vegetation begins to die off, the desertification process begins to speed up With the loss of plant life comes the loss of oxygen and other valuable resources that feed an area– and the whole planet
With desertification, a whole ecosystem can die– and remove from the planet all of the much-needed natural resources that ecosystem used to provide And it’s a problem that doesn’t simply affect some animal in plant life in one small area; desertification also affects man in several key ways And one of the most important is flooding
Trees do more than create oxygen and feed ecosystems; their roots also anchor the soil into place, keeping it firmly where it belongs But when trees and their roots begin to die, catastrophic flooding and mudslides become much more common These floods kill people and damage ecosystems in the here and now; this isn’t something that we can let future generations worry about, because it is affecting mankind every day If that’s not enough, the lower levels of oxygen brought about by the process of desertification also speed up the progression of global warming
