What will happen if all tress and plants on earth are cut down?
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 among 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.
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.
Desertification isn't a simple problem, and because it's caused by many factors no one solution will fix it. But there are things that the environmentally conscious among us can do to help prevent future desertification. One is using and encouraging the use of less paper in day-to-day life. Recycle paper and do what you can to live paper-free in your home and office. Another is working to pass legislation that will control the amount of wood that can be taken from any one area, or the amount of cattle that can graze in an area.
Huge issues like global warming require huge --and difficult-- solutions. But desertification, though complex, takes place locally, and on a smaller scale than something like global warming. And while this makes desertification receive less attention than it deserves, it also means that your efforts can make a difference in your area.
Ozone layer degradation
Chemicals that are present in various household or cosmetic products such as spray net for hair grooming have contributed to the degradation of ozone layer; exposing us to direct heat of the sun in a level higher than we experienced.
Our constant development requires that particular areas where there are rare animals with a short survival rate have to be suited with our requirement to expand and develop and most of the times we ignore the importance of these rare species.
The more forest we lose the faster rate we will experience water degradation. Someday water will be more expensive than petrol. We should remember that water is one of our life support, we used to drink water for free. But now if you will notice, bottled water is becoming a necessity and the cost is gradually increasing.
Among the environmental problems that we have to consider is human and cultural degradation, indigenous people or natives to certain places are maintaining their culture and are reminding us of our origins and our ways are being invaded by our modern culture. The reason why we have so much disaster in our environment is that we have forgotten the essence of our existence. The environmental problems that we are facing are actually interconnected and only we can do something about it, because we were the ones who created it in the first place.
A course of increase occurring in earths surface and atmosphere are referred as global warming. Over the last century, research have proven that global temperature has increased by one degree Fahrenheit. Industrial age have paved way to the increase of carbon dioxide and build up of other greenhouse gassess in the atmosphere.This trigger a deliberate warming in the planet.
Reasons behind it...
Carbon emissions - Carbon dioxide traps the heat of the sun on the globe, much like a veritable balloon filled with warm air. On an average day, humans add to the atmospheric level of carbon dioxide in several ways, from power plants to vehicles. Air pollution from industrial plants is increasing at an alarming level despite steps taken to enforce environmentally friendly practices.
Deforestation - Deforestation is another aspect of global warming. Deforestation is viewed as the primary driver of the increased in carbon dioxide in the environment. Human activities expanded to the extent of destruction of rainforest. With lesser trees to absorb CO2, global warming prevails and challenges the existence of humanity.
The dire consequences
Weather patterns - Drought is a state of inadequacy of water supply in a given place. Most harmful consequence brought by drought is starvation. As farmlands are destroyed by drought, crop yields declined. This results to famine in less developed and undeveloped countries.On the contrary, drought may results to stronger rains,severe floods and even hurricanes and tsunamis.
Health - Air pollution is a very convenient tool to spread diseases. Polluted air makes it easy to impair and destroy a persons respiratory system. Nowadays, young generations were victims of air borne diseases, allergies and fatal diseases such as malaria, cholera and dengue fever.
Adverse effects on wildlife - Every now and then, it's not surprising to hear the extinction of our wildlife. How can we expect these little creatures to survive if we are destroying their habitat to pursue and satisfy our need for an industrialized lifestyle? We invented technology to make our life easier at the expense of these creatures' survival. When are we going to recognize our mistakes?
What measures you can take?
Curb pollution factor - Fighting any forms and faces of pollution will definitely make a change. Global warming can be stopped and mother earth will be rescued. We are the creator of this technology and should be aware of its negative features. We have to act now and start working for a healthy environment. We have to work on using more alternative energy sources from solar power, wind power that are considered as clean energy sources.
Legal compulsions - Governing bodies started to act to solve this problem by passing some laws that will evaluate the creation of machines and its adverse effects to nature. These laws aim to protect our ecology and environment and continue to preserve on what is left after the destruction. In addition to this, local governments created programs designed to promote awareness to people about renewable energy sources.
Environmental degradation may be defined as the deterioration of the environment through depletion of resources such as water, soil and air; the destruction of ecosystems and the extinction of wildlife. Environmental degradation has occurred due to the recent activities in the field of socio-economic, institutional and technologies. Environmental changes are dependent on a variety of factors including economic growth, population growth, urbanization, intensification of agriculture, increasing energy use and transportation. Poverty still remains a problem at the root of several environmental problems.
Agricultural development and farming activities contribute, to soil erosion, land salination and loss of nutrients. The green revolution and over exploitation of land and water resources, and use of pesticides and fertilizers have increased to many folds resulting in land degradation and water logging.
Water pollution and scarcity:
Leaching from overuse of pesticides and fertilizers is an important source of contamination of water bodies.
