Causes And Effects Of Deforestation

This plays a crucial role in the precipitation cycle of South America and pumps oxygen into the atmosphere.Thousands of square miles of rainforest are cut down each year, releasing global warming pollution in the form of carbon dioxide and methane from burning and decaying vegetation. Deforestation disrupts the water cycle by allowing water to runoff directly to rivers rather than being trapped in soil and vegetation and slowly released throughout the year. This makes the forest more vulnerable to drought and the further loss of trees and release of global warming pollution. As of the results the researchers predict it will be a dessert by 2050. This causes the animals and plant their to die or extinct forever which may affect us in long terms.This shrinking of the Amazon rainforest is a major reason why scientists predict that vegetation will shift from its current state as a carbon sink to a carbon source by the middle of the

Deforestation is a concerning issue that has come about within the past decade that hasn’t been getting much attention. Deforestation is defined as the clearing or removal of a forest or group of trees where the land is not used for forest use afterwards. The land could be used for urbanization, farms, ranches, extra land, or anything that the country needs that piece of land for. Deforestation has become more common and the industry for it has increased rapidly. Although so many people have increased the amount of deforestation, they don’t realize the effects that it can bring upon the world and its environment. Deforestation not only affects the United States, but effects countries all over the world in multiple ways. Each way that

Since the beginning of time, every single living organism on this planet has come to depend on one important thing, oxygen. One of the main sources of this life necessity is our trees. Trees are known to filter the air of many harmful pollutants and absorb carbon dioxide, making the air we breathe fresh and clear of toxins. But what happens when this source is eliminated from the environment? Deforestation, the removal of forests/trees, is a major ongoing issue that, not only has been happening for centuries, but is very well still occurring today. Although there are some positive aspects of deforestation, including building more communities, there are also many negatives that outweigh the positives. Scientists have estimated that between the years 1990-2015, the Earth lost approximately 129 million hectares of forest. The results have been catastrophic and include increased amounts of CO2 into the atmosphere, the impending extinction of various different species, and major changes in the weather.

There are a number of negative effects of deforestation in the Brazilian Amazon such as climate change, extinction of endemic species of rich biodiversity and destruction of home of indigenous people. First of all, climate may vary and deteriorate because of deforestation. Especially green house gas emission could have significant impacts on earth residents. Because it is calculated that Amazon rainforest contains about 10% of all carbon in the world, which total release will be disastrous. The deforestation of Amazon is responsible for the most greenhouse gas emissions which are the results of logging and burning of Amazon could have serious impacts to the whole world, including global warming (Butler, 2007). For instance, increase of 0.8 C from 1880 was indicated and especially two last decades of 20th century were hottest ones. Moreover, effects of it can be considerably felt in Alaska, Eastern Russia and Canada, where the double increase of temperature compared with total average was indicated (National Geographic News 2007). Another damage that deforestation could make is runoff of Amazon River. It is estimated that if “widespread deforestation” arise, there will be 20% increase in runoff, which could be

The Brazilian forest is known to produce around ten percent of the current greenhouse gasses, which contributes to global warming. Deforestation is also the leading cause of loss in forest cover in forests. When there is no forest cover in an ecosystem the soil can become eroded when rain events occur, causing the soil to move downward which causes damage to the habitats. Clear cutting the forest can not only impact the species and plants that are living there, but also the indigenous people that have been living there for

In fact if more trees are cut down, habitat of animals could be destroyed and we could end up with extinct species as mention before. Not only does this affect the Amazon alone, but it affects the whole southern part of America. With the reduction of trees the capacity to absorb carbon, modified water cycles, and soil, deforestation and climate change could cause the Amazon to be replaced with savannah like vegetation. With a big alternation to the ecosystem like the savannah could distress Brazil. If the ecosystem is distress this can cause changes in temperature, and rainfall is the increase like hood with extreme weather events. These events are usually caused by the climate change and regional deforestation. Events such as droughts and floods are part of the natural rain forest climate change, but alternation to the climate change can bring severe weather change. This can hold a negative impact on suburban areas with transportation, agriculture, and businesses going out of business due to extreme weather events. The climate change is not only important but it can cause a distress to the Amazon rain forest that deforestation is not an option to continue.

As parts to of the world still continue to commit acts of deforestation in the rainforest areas, at the same time, the climate on earth also becomes affected by these actions, too. The trees in the rainforest are essential to the water cycle (Szalay). The water cycle is the movement of water on the earth (“Summary of the Water Cycle”). The trees in the water cycle act in the process of evapotranspiration. The word evapotranspiration is evaporation and transpiration together (Briney). Evaporation is when water converts from liquid into a gas or vapor (Briney). Transpiration, however, is when a plant or tree absorbs the water from their roots and is evaporated back into the atmosphere through its leaves, stems, or flowers (Briney). The water evaporated from the trees and plants contribute to the rainfall in the forest (Briney). In the article The Effects of Deforestation in Amazonia, author Harald Sioli states, “With the reduction of rainwater re-evaporating from the original forest, the rate of its recycling will also diminish” (200). If the process of evapotranspiration decreases due to deforestation, the amount of rainfall will also decrease. The rainforests like the Amazon will change in climate and become dry and could possibly cause more forest fires due to the reduction of precipitation in the rainforest (Shukla, Nobre, & Sellers).

Have your eyes ever set on a barren land where even technology can’t reverse the damage we have caused? We care mostly for the present, but we must never forget to see to the future and in this case the deforestation of the Amazons. “Deforestation is considered the second largest anthropogenic source of carbon dioxide to the atmosphere” (Song et al. 2). Each day we are wiping out miles of trees from one of our most diverse ecosystems in the planet, and one of our largest “lungs” in the world. At our rate of destruction of the rainforest, we would have inflicted in our future a great disservice, as the trees cut down would no longer give us clean air and more CO2 would pollute our air. CO2 can have a negative impact on our health. As we breathe in this air, it can lead to lung cancer and other diseases. By destroying the Amazon ecosystem we could drive many exclusive species that only live in the Amazon to extinction. Will we know the harm we have caused right away? Probably not, but we will definitely find out sooner rather than later. The cause of the Amazon deforestation is due to our need for wood to stay warm, and for developing countries to use it for fuel. Our top priority in conserving the Amazons is the unforeseen environmental impact that can be caused to our planet and to us. “Tropical deforestation also has other negative externalities, such as the loss of biodiversity, erosion, floods, and lowered water levels” (Jusys).

Deforestation around the world has not only affected the forests in which species live in but now is being recognized as one of the main causes of climate change. Since the destruction of the rainforests has sped up in recent years, a cooling band around the equator forms and those emissions can outweigh any

2017). Deforestation also indirectly affects the water cycle by disturbing the atmospheric circulation patterns. As evapotranspiration occurs in the water cycle from the forests, the water rises up to the atmosphere and the wind moves the rain. So when trees are cleared, the cycle of losing natural resources continues as fewer trees lead to less water to evaporation in the water cycle which decreases the precipitation the Amazonian forest need. This finally leads to more death of trees and the ecosystem within the forest. Zemp et al.’s result on forest resilience in their simulation supports that the Amazon’s forest survival also decrease as there is an overlap in Zemp et al.’s statement when they state that in their simulations, forest resilience decreases overlap with deforested areas. Despite the evidence showing the detrimental effects of deforestation, Zemp et al.’s research focus on the quantity of the forest and deforestation, therefore, the research has a gap such that other geographical influences such as fertilization, greenhouse gases, and water use are not accounted for. However, Zemp et al.’s had gained more understanding as they have used other research papers, like [Spracklen and Garcia-Carreras, 2015; Lejeune et al., 2015], to close the gap of unanswered gaps in the deforestation issue. Although the paper has

There is a chain reaction due to deforestation. Deforestation leads to decrease in biotic pump disrupting the water cycle leading to a decrease in transpiration and increase in temperature. Such rise in temperature leads to lack of rainfall, increase droughts and forest fires to which the fires will disrupt the water cycle even more. The effects of deforestation on Amazon forest resilience research by Zemp et al. (2017), build upon previous research done in the field of forestry studies and used similar methods to collect data. Although they have come to some shortcomings such as the risk of underestimating the differences which are introduced in evapotranspiration following deforestation, compared to study using fine-scale observations

The change in the Amazon is already affecting our daily life. In Sao Paulo, the biggest city in the American Continent, has been suffering with the worst drought ever. And it is all because the Amazon pumps into the air moisture that will turn into rain in the Midwest, Southeast and South of Brazil. The higher the deforestation, less moisture and therefore less rain. And without rain, the reservoirs are empty and taps

A study published by an international team of scientists warns the Amazon is being largely impacted by dams, mining, overfishing, and deforestation. In this transect the focus will be deforestation

Genetic engineering is a recent development that has gained tremendous commercial appeal. The potential benefits of genetic engineering have captivated the general public and clouded their moral values. The ultimate goal of genetic engineering is to create a utopian society where problems such as disease and world hunger no longer exist. Genetically engineering humans to be ideal beings may eventually lead to the creation of a “super race.” A super race is a race of strong, healthy, and highly intelligent individuals who contribute to the advancement of society. Despite the attractive potential benefits of the creation of a super race, there are several potential negative consequences that may not all be foreseen by humans. Tenzin Gyatso, the world’s fourteenth Dalai Lama, chimes in on the discussion of genetic engineering in his article, “Ethics and the New Genetics.” He, too, sees the “obvious and wonderful benefits” (Gyatso 132) of genetic engineering; however, he warns his readers of the social, political, and ethical ramifications that may result from genetic engineering. Gyatso reminds humans of the great responsibility that comes with new knowledge and power. In Brian G. Henning’s review of “The Case Against Perfection,” Henning discusses the dangers that may result when humans try to perfect nature. In order to move forward with the technology available, the world needs ethical considerations in regulation of development. In order to make decisions in the area of

Imagine living in a world without trees. It is nearly impossible because trees play such a crucial role all throughout the world by providing the earth with a home for plants and animals, natural resources, and protection. If the current rate of deforestation continues a world without trees could become reality. According to National Geographic, deforestation is defined as “clearing Earth’s forests on a massive scale, often resulting in damage to the quality of the land” (“Deforestation and Its...” ❡1). Since early times trees have been used to benefit humans without regard to the harm it has caused. The United States was 46 percent forested before the European Settlement and by 1907 was already only 33 percent forested (Becker ❡2). Although it can be used for developmental and agricultural purposes, deforestation has a negative impact on the earth that has a detrimental effect on humans, animals, and plants.
