Recommended: depletion of forest and its effects
Forests and trees keep our planet cool, but every year more forests are being destroyed than preserved. Deforestation is a large contributor to animal extinction through loss of habitat and global warming through loss of natural carbon sinks. As of 2016, about half of the world’s land has been deforested and about 18 million acres of forest are lost per year. This is substantial because deforestation will devastate the animal kingdom and significantly impact our future children. The government can be a powerful asset in this matter and there are a number of ways to do that. The government should fund projects to develop a more sustainable construction material to decrease the use of wood. They should endeavour to minimize deforestation and …show more content…
Fires can take out many acres of trees and destroys many forests along the way. This can lead to government spending tons of money and man-hours to stop the fire or let nature burn all of it down. Then the land is left burned and no one to replant trees. “Hundreds of trees are lost each year due to forest fires in various portions of the world. This happens due to extreme warm summers and milder winters” (conserve-energy-future 2). This quote backs up my claim and my thesis because government would need to spend more money on forest fires to help it return the way it was before. This is relevant because in the past when government got involved and invested billions to help deforestation, we have seen outstanding result and millions of cubic meters of deforestation being …show more content…
This means that there are 422 trees per person. Then the author discusses how this isn’t necessarily a good thing and that the spread of human influence decreased the amount of trees by 46 percent. His articles states, "The U.S. had 319 million people in 2014, but 228 billion trees. That 's 716 trees per person. Brazil had 301 billion trees (1,494 per person), Canada 318 billion (8,953 per person), and China 139 billion (102 trees per person). Among highly populous countries, India (population, 1.267 billion) had a tree population of only 35 billion, leading to just 28 trees per person” (Mooney 1). The statement above gives statistics on the amount of trees there are in the some of the biggest countries in the world. This is relevant because it shows which country will need aid in the deforestation problem
Now is a critical time to address the issue of deforestation. Around the world forests are logged for timber and paper pulp. South America contains a large amount of mahogany and rosewood—highly coveted types of wood—within the Amazon basin. Forests are also cleared to make room for the planting of cash crops, such as coffee and soy, as well as livestock farms. After only a few years, overuse of these lands for crops typically causes soil erosion that quickly turns deforested regions into wastelands. Deforestation is responsible for 20 percent of global greenhouse gas emissions, which is more than all emissions all motorized transportation added together. The destruction of forests does not just threaten our climate; it threatens the livelihoods of billions of people that rely on forests for food and economic activities. The modern world relies on rainforests more than for the well-known reason. People receive many of their fruits and medicines from plant species that survive solely within the heart of a rainforest. Let’s not forget that forests also serve as habitats to wildlife a...
There are many species of trees that get turned into lumber and then manufactured. By harvesting lumber, we are cutting down many trees which are very important to many cycle in the environment. Fortunately we are able to grow back. Forests are burned or clear-cut to facilitate access to, and use of, the land. This practice often occurs when the perceived need for long term sustainability is overwhelmed by short-term sustenance goals. Not only are the depletion of species-rich forests a problem, affecting the local and regional hydrological regime, the smoke caused by the burning trees pollutes the atmosphere, adding more CO2, and furthering the greenhouse effect. For thousands of years, wood has been used as a building material and the fact is wood has huge environmental benefits over other building products. It is completely biodegradable, works as an effective insulator, and is 100 percent
Deforestation has accumulated many multifaceted controversies over time. The main one, however, is the impact deforestation has on water flow. People have different perceptions on how deforestation affects the flow of water, this lead to a controversy between conservationists and a group of theorists. Many years ago, water was used as a way for almost all the mills to function. Changes in the ecosystem depend on the rate and extent of deforestation and determines how drastic the changes will be.
“The benefits of deforestation far outweigh its impacts.” How far do you agree with this statement? With reference to examples, explain your stand.
Deforestation is fast becoming one of the world’s worst environmental/geographical occurring disasters known to mankind, and is due to humankind’s greed, ignorance and carelessness when considering the future of our environment.
“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
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.
This is alarming since recent data indicates these enormous forests are land-dwelling carbon absorbers that could help to slow worldwide climate alteration. The United Nations ' Food and Agriculture Organization (FAO) estimates “eighteen million acres of forests have been destroyed worldwide;” and NASA forecasts “that if current deforestation rates are not reduced, rainforests could become entirely eradicated in a century.” The nations with substantial deforestation are Brazil, Indonesia, Thailand, Africa (The Democratic Republic of Congo included), and remote areas of Eastern Europe. Indonesia, the country with the greatest deforestation within the last century, has lost approximately forty million acres of indigenous
Did you know that the homes of 50% of plants and animals are located in tropical rainforests (“Rainforest”)? Well, this is indeed true. All of the world’s tropical rainforests are a crucial part to plants, animals, and even humans, as they provide us with several benefits: oxygen, climate, living conditions, and many more (“Panda”). But in the more recent decades as the economy is evolving, the human race has seen the need to take more of the tropical rainforests and other natural resources to fit their daily lives. Little do they know, animals, plants, and Mother Nature are being destroyed slowly as forests and lands are being
The world’s rain forests could completely vanish with in a hundred years due to the rate of deforestation (Deforestation). Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. Not all deforestation is intentional. Deforestation can be split up among 4 main factors: 5% caused by cattle ranching, 19% over-logging, 22% from palm oil plantations, and 54% from slash-and-burn farming. They are not the only thing that is causing harm to the rainforest though. There are many other things such as Cash Crops, Shifted Cultivators, Cattle Ranching, Mining Operations, Government interest, and Hydroelectric Projects, and Plam Oil
This article describes the history of deforestation around the world and explaining how deforestation started as part of a civilizing process. Then the article tells that human populations increase causes deforestation because humans need more land for food, water, and for living purposes. Also in the last part of the article it talks about how the future of deforestation is worse than the present, even with our reforestation efforts the environment is being destroyed to fast for us to stop especially in the
Trees have the ability to release water into the atmosphere during certain stages of photosynthesis which in turn aids in replenishing clouds and maintain rainfall, but with the removal of said trees the barren land will now become drier. With the environments weather now adjusted to be more of a dry climate, and the loss of shelter the biodiversity has now decreased. If said forest harbored animals that were unique to its region it has now caused a global issue because that animal has potential to go extinct. Scientists have only tested about one percent of the plant population in the rain forests, but they often of times find plants that can have many medical benefits, so with the expansion of deforestation the opportunity to discover the medical uses for such plants becomes more limited. The change in climate also affects other areas that deal more directly with the human
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...
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...
Commercial logging for lumber or fuel supplies is another factor. The cutting down of trees for a profit is also depleting our forests. Another travesty of commercial logging is the damage caused to other trees that surround or are in the path of the trees being harvested. Logging also increases the destruction to forests in the event of fire as outline in the article entitled “Deforestation in Brazilian Amazonia: History, Rates and Consequences” written by Philip M. Fearnside, “Logging greatly increase the susceptibility of forest to fire. Once fire enters it kills trees and increase...
