The Effects of Deforestation

The Effects of Deforestation

Deforestation is the process of converting forested lands into non-forest sites that are ideal for crop raising, urbanization and industrialization. Because deforestation is a serious concept, there are also serious effects to the surroundings.

Effects of deforestation can be classified and grouped into effects to biodiversity, environment and social settings. Because deforestation basically involves killing trees in forests, there are so many effects that can be enumerated as results of the activity.

When forests are killed, nature basically requires people to renew the forest. Reforestation is one concept that is in the opposite direction as deforestation, but is proven to be a much harder effort than deforestation.

So the rate of deforestation has not been offset by the rate of reforestation. Thus, the world is now in a troubled state when it comes to issues concerning the environment.

Pollution is rapidly growing along with population. Forests are greatly helping reduce the amount of pollutants in the air. So, the depletion of these groups of trees is greatly increasing the risk that carbon monoxide would reach the atmosphere and result in the depletion of the ozone layer, which in turn results to global warming.

Environment change

One major effect of deforestation is climate change. Changes to the surroundings done by deforestation work in many ways. One, there is abrupt change in temperatures in the nearby areas. Forests naturally cool down because they help retain moisture in the air.

Second is the long process of global climate change. As mentioned above, deforestation has been found to contribute to global warming or that process when climates around the world become warmer as more harmful rays of the sun comes in through the atmosphere.

The ozone layer is a mass of oxygen or O3 atoms that serves as shield in the atmosphere against the harmful ultraviolet rays from the sun. Because ozone is made up of oxygen atoms, oxygen react with carbon monoxide. Such reaction would use up oxygen atoms.

It follows that when there are more carbon monoxide atoms going to the atmosphere, the volume of oxygen would decline. Such is the case of ozone depletion.

The third effect to the environment would be on the water table underneath the ground. Water table is the common source of natural drinking water by people living around forests.

Water table is replenishing. That means, the supply of water underground could also dry up if not replenished regularly. When there is rain, forests hold much of the rainfall to the soil through their roots.

Thus, water sinks in deeper to the ground, and eventually replenishing the supply of water in the water table. Now, imagine what happens when there is not enough forests anymore. Water from rain would simply flow through the soil surface and not be retained by the soil.

Or other than that, the water from rain would not stay in the soil longer, for the process of evaporation would immediately set in. Thus, the water table is not replenished, leading to drying up of wells.

Effect to biodiversity

Forests are natural habitats to many types of animals and organisms. That is why, when there is deforestation, many animals are left without shelters. Those that manage to go through the flat lands and residential sites are then killed by people.

Through the years, it is estimated that there are millions of plant and extinct animal species that have been wiped out because they have been deprived of home. Thus, biodiversity is significantly lowered because of the savage deforestation practices of some people.

Wildlife advocates have been constantly reminding that several wild animals left in the world could still be saved if deforested forests would only be reforested and the practice of slash and burn of forests would be totally abandoned.

Social effects of deforestation

Deforestation is hardly hitting the living conditions of indigenous people who consider forests as their primary habitats. Imagine how they are rendered homeless when forests are depleted. These natives would be forced to live elsewhere, and are usually left to becoming mendicants in rural and urban areas.

Overall, effects of deforestation cannot be offset by the contribution of the practice to development. While it is logical that progress is very much needed by mankind, it must also be noted that nature knows no defeat. Destruct it and it would certainly retaliate, one way or another.

The Harmful Effects of Deforestation

The Harmful Effects of Deforestation

Human beings always have been and probably always will be to some extent dependent on forests. Trees were their habitat, their environment, their source of food and their protection from enemies. Forests are very important to man, and other organisms, and one of the biggest problems the world is facing today is the threat of totally losing the forests due to massive deforestation and suffering the harmful effects of deforestation.

Deforestation can be defined as the large scale removal of forests. Deforestation occurs when forests are converted to non-forest areas for urbanization, agriculture, and other reasons without sufficient reforestation. It is the permanent destruction of forests and woodlands.

At present, forests are considered among the most endangered on the planet. Everyday at least 80,000 acres of forest vanish from Earth. The Food and Agriculture Organization (FAO) of the United Nations show that the rates of deforestation has not abated and has actually increased by 8.5% from 2000-2005 compared during the 1990s. FAO has approximated that about 10.4 million hectares of tropical forest have been permanently destroyed from 2000-2005 compared to 10.14 million hectares in the period of 1990-2000.

The process of deforestation is often a complex pattern of progressive fragmentation of the forests. Mistakes of this sort could lead to forest destruction. Along with this destruction is the extinction of many species, heavy soil erosion, greenhouse effect, silting of rivers and dams, flooding, landslides, denuded upland, degraded watershed, and even destruction of corals along the coast.

Extinction of Thousands of Species - Destruction of the forests leads to a tragic loss of biodiversity. Millions of plants and animal species are in danger of disappearing as a result of deforestation. Tropical forests are much more biologically diverse than other forest and a very serious effect of deforestation in tropical countries is the loss of biodiversity.

Heavy Soil Erosion - One function of the forest is that its roots hold the soil in place. Without trees soil erosion and landslides easily happen. When heavy rains and typhoons come, soil is easily carried to lower areas especially to communities at the foot of the mountains.

Greenhouse Effect - Deforestation increases the amount of carbon dioxide in the atmosphere. The conitnued degradation of our forest heightens the threat of global warming because the trees and other plants that takes up carbon dioxide from the atmosphere to be used for photosynthesis are gone. The burning of wood or its decay contributes to the release of more carbon which combines with oxygen in the atmosphere thus increasing further the levels of carbon dioxide that causes greenhouse effect.

Silting of Rivers and Dams - Deforestation results in the silting of rivers sediments deposit which shortens its life span and clogs irrigation system. As a result of deforestation, the reservoir behind many dams are filled with sediments more rapidly than expected.

Flooding - One major importance of forest is that they absorb water quickly in great amount during heavy rains. But due to massive deforestation there are no trees to absorb the water thus resulting to the loss of many lives.

Landslides - The roots of the trees bind soil to it and to the bedroock underlying it. That is how trees prevent soil from getting eroded by natural agents like wind or water. When trees are uprooted, there will be nothing to hold the soil together thus increasing the risk for landslides which can cause seriously threaten the safety of the people and damage their properties.

Denuded Upland - After several harvests of the forest the cleared land is no longer suitable for planting trees. It has become a desert. The transformation of a forest to a semi-desert condition is called desertification.

Degraded Watershed - When forest mountains are denuded, watersheds are degraded and this leads to the loss of sustained water supplies for lowland communities. This is because trees affect the hydrological cycle. They can change the amount of water in the soil, groundwater, and in the atmosphere.

Destruction of Corals along the Coast - Coral areas are degraded and coral reefs are affected by siltation. As a result of deforestation there is an increase of flooding during the rainy seasons and decreased stream flow in dry seasons.

The forest provides us with many products and important services. It stops soil erosion, refreshes the air, and protect us from typhoons and other calamities. But if rampant deforestation is not controlled it will result to several problems. In one way or another, the denuded forests will back fire and people will certainly lose to the harmful effects of deforestation.
