The Positive and Negatives of Deforestation

The Positive and Negatives of Deforestation

Earth and the lives of everything that depends on it - from the smallest bacteria to the largest sea creatures - rest on a delicate matter and that is balance. A single, seemingly harmless disturbance in this balance has consequences that are both beneficial and disadvantageous. One of these is deforestation.

Deforestation has always been a practice of many developing communities and has contributed greatly to civilization as we know it today. Unfortunately, much of the ill effects of deforestation is caused by greed, bad agricultural practices and government neglect.

Why forests are important -

Other than for their beauty, forests are highly responsible in keeping and sustaining global ecosystems. In fact, much of the quality of life we enjoy, we owe to the forests. It is also the home of more than half of all creatures and organisms in this planet. From food to life-saving medicines, forests give mankind a variety of gifts that contribute much to our quality of life.

The positive consequences of deforestation -

Depending on the needs of the social group concerned, deforestation has made it possible for communities to be built. Forests make way for residential houses, office buildings and factories. Governments are able to build roads to make trade and transport easier and therefore more convenient to residents.

Deforestation can also mean the conversion of forest land to productive land for agricultural uses. This results in better and more abundant production of food and materials, virtually eradicating periods of want and lack. Economically, deforestation has contributed much in giving many communities the opportunity to make positive changes in their lives.

The negative consequences of deforestation -

Unfortunately, the negative consequences of deforestation far outweigh its positive effects. Here are a few of them:

1. Exposing soil to heat and rain. When forests are cleared, soil cover, which consists mainly of vegetation, is removed as well. This exposes the bare soil to extreme conditions produced by the sun's heat and rainwater.

With these activities alternating, the soil quickly compacts. As rainwater flows, it will wash out the nutrients and other organic materials that make the soil rich and fertile. Add to that the frequent activities of tilling, cropping and grazing which gradually results to the degradation of the soil's quality.

These practices are specially a concern in areas where forest zones are drier. Agriculture practice on top of deforestation can result to the desertification of many areas. Desertification is also a direct result of the demand for the soil to produce more (as a consequence of the increase in human population), thereby decreasing to a significant degree the land's carrying capacity.

2. Flooding. Deforestation can result to watersheds that are no longer able to sustain and regulate water flows from rivers and streams. Trees are highly effective in absorbing water quantities, keeping the amount of water in watersheds to a manageable level. The forest also serves as a cover against erosion. Once they are gone, too much water can result to downstream flooding, many of which have caused disasters in many parts of the world.

As fertile topsoil is eroded and flooded into the lower regions, many coastal fisheries and coral reefs suffer from the sedimentation brought by the flooding. This results to negative effects in the economic viability of many businesses and fatalities in wildlife population.

3. Non-suitability of deforested areas for conversion. Most of the areas that have undergone deforestation are actually unsuitable for long-term agricultural use such as ranching and farming. Once deprived of their forest cover, the lands rapidly degrade in quality, losing their fertility and arability.

The soil in many deforested areas is also unsuitable for supporting annual crops. Much of the grassy areas are also not as productive compared to more arable soils and are therefore not fit for long-term cattle grazing.

4. The displacement of indigenous communities and their traditional way of life. When governments decide to offer forests for deforestation mainly to open up areas for 'civilized' communities, access to forest resources by indigenous peoples are ignored. In fact, indigenous peoples are hardly included in economic and political decisions that directly affect their lives. This encroachment ignores their rights as much as it takes away the resources that their ancestors have bestowed upon them.

5. The loss in the number of biodiversity. This is probably the most serious consequence of deforestation. Put simply, it means the destruction and extinction of many plant and animal species, many of whom remain unknown and whose benefits will be left undiscovered.

Each year, as deforestation continues, much of the wilderness from which we benefit and would have continued to benefit from will be lost forever. With it are the millions of chances in the form of plants and wildlife that could bring us many economic and medical solutions to pressing problems we currently face.

While it's true deforestation has brought with it opportunities to improve our lives, we have not mastered the right kind of responsibility that goes with having control over our planet's resources. As a result, we and all the other creatures on this planet suffer greatly from the consequences of our actions.

Some Of The Facts About Deforestation

Some Of The Facts About Deforestation

Deforestation is a permanent destruction of forests and woods. Deforestation is the conversion of forested area to the non forest land for the use of industrial gain, livestock, and urban use. In the ancient times, most of the land was covered with forests. As the population and other demands damage the earth and it leaded to deforestation.

In all over the world the rate of the destruction of forests is unimaginable. Nearly half of the mature tropical land is destroyed. As the humans are more conscious for searching of new accommodation, and making urban areas, they have become the largest cause of deforestation.

Examples of Deforestation:

Many tropical countries are the victims of deforestation. For example:
• Philippine
• Central America
• Nigeria
• Ethiopia
• Brazil

Other than the beauty, forests are responsible in keeping the world healthy and green. If we are enjoying the quality of life, it's just because of forests. Forests are the gifts that contribute to our quality of life. Deforestation has always been a practice, which is dangerous for lives. Unfortunately all of the negative effects of deforestation are caused by bad agricultural practices, and negligence on the part of government.

Causes of Deforestation:

Deforestation is happening due to many reasons. Some are the common reasons are:
• Urban and Construction purpose
• Population growth
• To grow crops
• Agricultural practices
• To create cattle grazing lands
• Climate change
• Cut the woods for using fuel
• Clearing forests for mining and oil exploitation
• Making roads and highways
• Slash and burn forming techniques
• Wildfire
• Acid rain
• Greenhouse effect
• Making products from woods

Consequences of Deforestation:

There are two types of consequences of deforestation:
• Positive Consequences
• Negative Consequences

Positive Consequences:

Deforestation has made possible the needs of the social groups. Forests are the way for residential houses, building and factories. Roads are building for trading and easier transports. Deforestation also made possible to produce agricultural products. The lands are used for agriculture. This brought more productions of foods and other materials. Economically deforestation contributed much and made positive changes in the lives of humans.

Negative Consequences:

The negative consequences are:
• Exposing of soil
• Flooding
• Drought
• Disruption of water cycle
• Loss of biodiversity
• Climate change
• Desertification
• Shrinking beauty
• Increased population
• Irreversible environmental changes

How to prevent deforestation:

Deforestation should be controlled. There are some suggestions which should be considered.
• Reforestation/Plantation
• Wildlife sanctuaries: not only save the wild animals, but also save the woods and trees.
• Commercial forest plantation
• Water management: improper water management causes the deforestation. This should be controlled.
• Use recycled items
• Farming practices
• Become an advocate: learn how the person can spread the word.
• Support conservative organization: support the organization through donation, money, time etc.
