The Dangers Of Deforestation

By Sebanti Ghosh

Forests have a huge impact on the environment. The trees help in balancing the oxygen-carbon dioxide balance of the earth, by absorbing carbon dioxide from the environment and releasing oxygen. Forests regulate temperature of the Earth and rainfall, and thus prevent droughts. The trees impede the velocity of runoff on the soil surface. This thwarts soil erosion and landslides, thereby reducing possibilities of floods. The leaves that fall on the forest ground act as nutrient sources that increase soil fertility. The forests also offer shelter against adverse environmental conditions to diverse forms of wildlife. Moreover, forests are significant not just ecologically but economically as well. Firewood, commercial timbre, gums, raisins, medicines, and other products of industrial use are obtained from forests.

Over-exploitation of forests by humans has been continuing unabated through centuries. Increased urbanization has resulted in mass deforestation. Indiscriminate felling of trees for converting forest-lands into agricultural fields, for industrialization or mining, and overgrazing by domestic animals are all contributing to the loss of this exhaustible natural resource. Diverse forest ecosystems are being converted into high yielding mono-cultural tree plantations.

The lush green rainforests used to cover 14% of the surface of the Earth. Now this value has dwindled to only about 6%. It is anticipated that the remaining rainforests could disappear within the next fifty years.

The consequence is loss of biodiversity. Many species of plants and animals are already extinct. Others are also fading away, due to loss of habitat. Apart from the loss of genetic resources, this also entails loss of essential medicinal herbs and even several aboriginal tribes. Other major impacts include soil erosion, flooding, and desertization.

Perhaps the most severe outcome is global warming due to the greenhouse effect. Increased deforestation has led to the accumulation of greenhouse gases in the atmosphere, like carbon dioxide, methane, nitrous oxide and chlorofluorocarbon. This is heating up the atmosphere and the temperature of the world is rising. The resultant climate change would affect crop, animal and forest growth. Sea-levels will rise causing devastating floods, and at the same time severe droughts would occur frequently. Agriculture and aquaculture both will suffer. If timely steps are not taken to prevent this, the entire human race will be endangered

8 Basic Ways of Preventing Deforestation

By Nathalie Fiset

There have been so many discussions on the effects of deforestation in our environment. These effects range from alarming to catastrophic. We have read newspaper headlines that show the wreckage that natural disasters have done. Flashfloods have not only damaged millions of properties all over the globe but it has also collected lives. Landslides have done the same. These two are the results of nature’s balance that has been disturbed–they are the effects of deforestation.

Deforestation is the act of converting patches of forests to become areas of residence or industry. More and more businessmen are pushing through forests to obtain more land. Environment is sacrificed in exchange for profit. And this is a highly disturbing fact.

As an individual or as a part of the global community, you can do something to help prevent deforestation. Maybe you can’t fight off illegal loggers with your bear hands but with some basic ways, you can make a difference–no matter how small. Here’s a list:

1. If deforestation is a negative event, then a positive event should take place to counter its effects–reforestation. Plant trees and begin doing this in your yard. Trees give off oxygen that is essential for human existence and they, in turn, capture the carbon dioxide that humans and animals exhale. Trees also help in containing water in its roots. With this simple act, you are able to prevent soil erosion, which is the root cause of landslides!

2. Use recycled items such as books or pad paper, toilet paper, even shopping bags. If you can, do not waste any of these products so that no new raw material would be required to replace them.

3. If you are a farmer (or if you know someone who works as a farmer), try to rotate your crops. Instead of using a different portion of land each year, why not use the same portion with different crops? This practice also helps in maintaining the fertility of the soil. With the rotation of crops, not only is there a variety on the harvest each year, there is also the possibility of keeping that portion of land for as long as you can.

4. Cut down only the mature trees. Do not kill baby trees. And for every tree that is lost, plant another one as a replacement.

5. Join environmental awareness groups that would help you be an advocate of reforestation. In Washington, specifically in the Washington Middle School, there was a group of students that established a service-learning project. In their project, they asked a penny from each person. They explained that this money would help in buying acres of the rainforest in Amazon. Once this pushes through, no deforestation could take place in that purchased area.

6. There is a report that in Indonesia and Malaysia, more and more trees are cut down to produce palm oil. This massive destruction in the forests of both countries resulted into the loss of habitat for the native orangutans. With the loss of more trees, more animals become homeless. You can’t help prevent this altogether but you can limit your consumption of products that contain palm oil such as breads, chocolates, and even some cosmetics such as shampoo, soap or toothpaste. As to your food consumption, you can begin a diet of roasted or boiled foods instead of frying them.

7. Instead of using firewood, use coals to heat up your fireplaces during the winter season. Remember that it takes only a few hours to consume the firewood but it would take years to grow a single tree. Think twice before purchasing firewood again.

8. Support the laws or programs that were made to protect the forests and to stop any form of deforestation. Programs such as the Tropical Forestry Action Plan have done a major difference on the way deforestation is looked at today. This program spearheaded the discussion of tropical deforestation.

It is imperative to know that there is no such thing as a small, insignificant act when it comes to defeating deforestation. No matter how small your deed maybe, the important thing there is ‘every act can make a difference’. Deforestation can be prevented and you can be an active force in achieving that.

The Effects of Deforestation in our World

By Erin Hunt

The Effects of Deforestation in our WorldMany of the earth’s most delicate ecosystems have been affected by rampant and irresponsible deforestation. Although the dire effects are well known and documented by researches around the world, deforestation still persists by those who wish to flout the law. Why are forest ecosystems so valuable and what are the effects of deforestation in our world?

Among the ecosystems that currently exist, forest ecosystem have been widely recognized as one of the most efficient and delicate on earth. Forests are important ecosystems because they hold many important nutrients and help to recycle nutrients too. They are also important because they absorb and hold water thus making them a very rich and porous humus topsoil.

Deforestation happens when trees are cut down on a wide scale. This will lead to widespread disruption of a forest ecosystem. When a forest is cleared, the humus rich topsoil is left exposed leading to a number of dire consequences. The rain that falls on the exposed soil converts that rich topsoil into a sealed-off soil that is moist and muddy. It causes the soil to be washed easily into waterways. What is left behind is poor subsoil that leaves the land vulnerable to more natural erosion. In other words, deforestation leads to massive soil and land erosion.

When deforestation happens in tropical rain forests the effects are more devastating. It is because humus topsoil in tropical rain forests is known to be very thin and lacking in nutrients, so when deforestation occurs, the topsoil that is left behind is very vulnerable and will tend to wash away and erode easily. After deforestation in tropical rain forests, the only thing left is very poor nutrient, hard, clay-like subsoil that is not rich enough to sustain most forms of agriculture.

Sediments that are washed away eventually enter our drains, streams and rivers. These eroding sediments are often responsible for clogging up water channel leading to the problem of flooding. Soil erosion upsets surrounding ecosystems and has been known to be responsible for killing off the fishes and flooding reservoirs.

However despite all the ill effects, deforestation still happens around the world at alarming rates, especially in developing countries. A survey carried out by the United Nations Food and Agriculture Organization estimates that 33.8 million trees were cleared between 1990 and 1995 in developing countries. That area would be 3 times the size of France! Why? What is happening? It is because forests are ready source of timber and wealth and after the forests are cleared, there’s room for agriculture. Most of the agriculture is directed the to the planting of cash crops and grass and other crops to support greater beef promotion.

Global warming is a threat that will affect generations to come. The atmosphere surrounding us that supports life is a God-given gift. It must be protected. We should be leaders in efforts to curb global warming, not resistant followers.
