Wood is, and never was anything rare. Its varying strengths and weaknesses give timber the title of the ultimate building material. No one would ever believe that trees could ever be in danger. Yet anywhere from 46-58 thousand square miles of forests are lost each year, that’s equivalent to around 48 foot-ball fields every minute. The Amazon Rainforest alone has lost over 15% of its trees in the last 50 years, and considering the size of the forest, is a lot more than it seems.1 Trees have proven to serve much more than a nice kitchen cabinet. Thousands, if not millions of animals call forests their home or food. They even give oxygen, and take in carbon dioxide to keep this planet safe. “Forests are the world’s air-conditioning system--the …show more content…
Though there are some forests that were cleared completely by nature, but now it is practically impossible to find no connection to humans.5 Most of the time, when clearing a forest for plantations or cattle ranches, people will purposefully start a forest fire for a quick and easy solution. This not only ruins the soil, but attracts invasive species, decreases biodiversity, among many others. If not for humans, the earth would most likely be covered in rich forests, full of diverse vegetation and animals.3 It is obvious how urban cities affect deforestation, demanding for more products that shouldn’t be supplied, but no forests also affects urban …show more content…
Of course there will always be trees, at least for much longer than the life of forests, but the previous forest’s ground will lose its worth. At least 20% of the Earth’s greenhouse gas emissions are directly related to deforestation. Without vegetation to take in carbon dioxide, over 1.5 billion tons of it gets released into the air every year. Even the water cycle is affected. The lower the plants, the dryer the land, which leads to less rain overall, creating more desertification. The northwestern regions of China reported to have their rainfall average deplete by ⅓ from 1950 to 1980.5 “Humanity is cutting down its forests, apparently oblivious to the fact that we may not be able to live without them.” - Isaac Asimov. Even with the amount of deforestation, there are still ways for ay person to help slow the effects that could potentially harm the Earth
(Kumar et al., 2008a). Globally, 1.3 1010 metric tons of wood is produced by terrestrial
The controversy over logging, and more specifically clearcutting, is not a new issue in America. Ever since the 1920's and 1930's, when this nation started to become conscious of conservation, citizens have weighed the consequences of logging. Critics have questioned whether the increase in jobs, tax dollars, and economic growth was worth the destruction of forest lands. Regardless of what they believe today, the logging industry had become so efficient that by the late 1980's nearly 100,000 acres of federal land had been clearcut since the industry began. Logging technology has advanced rapidly in terms of speed, to meet the increasing demands for lumber, paper, and other products derived from trees. This in turn has greatly impacted the environment by severely degrading watersheds, leading to increased soil erosion, the diminution in the quality of drinking water, and the decline of fish stocks, among many other consequences. In this essay I will examine the progression of logging equipment throughout the 19th and 20th centuries and discuss how these changes in technology have not only changed the relationship of those who work in the industry, but also haw this has changed the wider relationship of society and nature.
Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).
Taking wood from rainforests and old-growth forests is detrimental to the environment and society. However, it is possible for us to have sustainable wood if we make an effort.
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.
There are many rainforests in the world but one of the biggest one is the Amazon rainforest, which is located in the northern half of South America and lies in the countries of Brazil, Colombia, Peru, Venezuela, Ecuador, and Bolivia. The Amazon also lies in between the Tropic of Capricorn and the Tropic of Cancer. The size of the Amazon resembles the size of the United States from the Atlantic Ocean to the Rocky Mountains. Since this rain forest lies next to the Equator, the climate is warm and humid. The average temperature is in between sixty-eight to ninety- three degrees. The Amazon has two seasons but each one is six months each. They are classified as the wet season and the dry season. The wet season occurs between December to May and the dry season occurs between June to November. The average rainfall is fifty to two hundred and sixty inches per year. The forest floor only gets up to two to five percent of sunlight since the canopy blocks the sunlight from getting to the forest floor. The Amazon rain forest got the nickname, the world’s pharmacy, because many medicines have been found in the tree bark, the tree’s leaves, and other parts of the trees.
On average millions of hectares of forests are destroyed each year resulting in severe consequences that will affect not only our lifestyle, but also all the animals with which we share our planet. Many species of animals and plants will become extinct and if we continue with the destruction of our forests, earth will be unable to sustain life.
Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
“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
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...
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 is the elimination of existing trees from the earth; attributable factors include urbanization, logging, ranching, and farming and to some extent land speculation. Land speculation can be included as cleared land is more valuable than forested land. Deforestation, done in the name of progress, and the long-term, devastating effects of it, is killing our planet.
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...
Trees are one of the most important parts of the biosphere. They provide oxygen, which is one of the largest producers of life. Humans live and strive off of oxygen every second of their lives. Not just humans need oxygen to survive and thrive on Earth, but animals, and other creatures on the planet do as well. Trees are a huge part of all life and if they were gone, there would consequently be no form of life. Not only do trees create all forms of life, but they create beautiful surroundings for an area and create a comfortable and shady environment for all surrounding life. Even though trees seem to be everywhere you look, the planet is losing billions upon billions of them a year. Anywhere from three billion to six billion trees are lost every year, ("How Many Trees Are Cut Down Every Year? Rainforest Action Network Blog. N.p., n.d. Web. 10 Apr. 2014”). With this fact in thought, it shows that planting one tree can create a bigger difference than you realize.
