Recommended: Effects of deforestation

Merriam-Webster defines deforestation as “the act or process of cutting down or burning all the trees in an area” (Def. 1). Sometimes, deforestation can occur unintentionally because of forest fires, changes in climate, floods, and insects. Most deforestation happens intentionally by humans in order to use the land for farms and cities or to use the trees for paper and wood products. This practice has existed since the dawn of man, and in that time, about 80% of the Earth's forests are gone. If we continue at this rate, all of the rain forests in the world could disappear in a hundred years. Deforestation is harmful because it can lead to biodiversity loss, soil erosion, and desertification.
According to the World Wildlife Fund, tropical rain forests hold about 80 percent of the known species on Earth, which is where a majority of deforestation is taking place. Endangered species that live in forests, such as bonobos, giant pandas, and Asian elephants, are especially at risk of extinction because of deforestation. When one certain species is wiped out of an area, it impacts the whole food chain in that ecosystem. This is known as the domino effect. If a certain plant is removed from an ecosystem, the insect that relied on that plant will die out from a lack of food. The snake that ate said insect will also have no food. Deforestation can have a disastrous effect on nearly every species living in the forest.
Deforestation not only affects living creatures, but the soil and nutrients in forests as well. When trees are cleared from an area, it removes the protective covering and shading that the plants in the forest need. If the plants die out, soil erosion occurs. The roots and water storages of trees, which hold soil and nutrien...

    The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.

  • Deforestation In The Amazon Rainforest

    Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .

  • Satire Of Deforestation

    854 Words  | 2 Pages

    Deforestation: an act of pure terrorism towards the forests of the Earth, the most evil and brutal punishment to wildlife imaginable. Every year, thousands of trees in multiple forests are chopped down either for the wood humans can make resources for or to make room for more humans to grow as they continue to rise in population. Many problems can result from deforestation: loss of habitat to animals that rely on the forest trees to survive, resulting in endangerment or extinction as the animals must forcefully move to another place to thrive in numbers while avoiding the invading humans, and the effects of potential global warming can occur due to the carbon dioxide released by the machinery used to bulldoze the trees down, and only a few

    Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.

    “The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests

    Though deforestation has increased at an alarming rate throughout the past fifty years, deforestation has been performed during the course of history. According to the World Resources Institute, a majority of the world’s enduring naturally occurring forests are found in Alaska, Canada, Russia and the Northwestern Amazon. Research has demonstrated forests are more likely to be destroyed and repurposed where economic revenues tied to agriculture and pasture are prominent, typically attributed to advantageous weather conditions, or lower expenses of demolishing the forest and delivering merchandises to the global

  • Deforestation and Biodiversity

    2666 Words  | 6 Pages

    Deforestation, defined by biologist Charles Southwick as "the destruction of forests; may involve clear-cutting or selective logging" (p. 365), is a predominantly human-driven process that is dramatically altering ecosystems worldwide. "Clear-cutting" involves the indiscriminant removal of every single plant and tree species from within a selected area. The other major process of deforestation, "selective logging," focuses removal efforts on only specific, predetermined tree species within a chosen area. The statistics gathered about human deforestation over time are considerable, and they can be somewhat controversial. Depending on the source and the location selected, the magnitude of deforestation varies. Southwick estimates that, approximately 10,000 years ago, 6.2 billion hectares (23.9 million square miles) of forest existed on earth (p. 117). That figure is equivalent to 45.5% of the earth's total land. He further estimates that, by 1990, this amount had declined 30%, with only 4.3 billion hectares of forest remaining (p. 117). Southwick also acknowledges other estimates that place the total amount of deforestation between 50% and 75% (p. 117). NASA has similar deforestation statistics that confirm these trends. According to their website, 16.5% of the Brazilian Amazon forests have been destroyed. They also note similar magnitudes of deforestation in Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), despite the significantly smaller total area of forest within these countries. These grim figures are somewhat tempered by the NASA finding that, over the past ten years, the deforestation rate has declined from 6,200 square miles per year to 4,800 square miles per year. Though this trend is n...

  • Discussion of the Issue of Deforestation

    604 Words  | 2 Pages

    Deforestation is the amputation of trees from forest areas more swiftly than they can be replanted or regenerate naturally. The fact that trees play an incredibly momentous part in stabilising climate, atmospheric composition and soil structure, removing trees rapidly becomes a major problem. There are numerous reasons behind the felling of trees by mankind. The Amazon basin is a prime example of humans exploiting rainforests. Within this tropical rainforest lie a vast variety of tree species, with many uses, giving humans even more reason to exploit this area.

    People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation.

  • Deforestation as a Major Problem

    3202 Words  | 7 Pages

    Scientists themselves are just beginning to understand the serious problems caused by deforestation. Deforestation occurs all over the world by all types of people. Peasant farmers even add to the problem because in most tropical countries the farmers are very poor only making between eight hundred and fifty four hundred dollars annually (NASA Facts). Therefore, they do not have enough money to buy what they need to live therefore they must farm to raise crops for food and to sell. In these poor countries the majority of people are peasant farmers this farming adds up to a great deal of deforestation. These farmers chop down a small area of trees for there plot to farm on and burn the tree trunks (NASA Facts). The combined number of farmers maintaining this process creates a great deal of clearing and burning of the land they need to cultivate, which results in land being treeless. Commercial logging is also another common form of deforestation. This commercial logging wipes out massive amounts of land sometimes deforesting several miles at...

  • Deforestation Essay

    875 Words  | 2 Pages

    Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?
