Soil Conservation
Soil is highly useful to us. We grow plants and trees in it. It holds the trees in place and supply nutrients and water to the plants to grow. The top soil is very healthy for plants to grow, and therefore, farmers take good care of the top soil for better yield.
However, a strong wind or heavy rains can easily remove the fertile top soil. The removal of soil by water or wind is called soil erosion. A forest is a great collector and storeroom of water. The root structure of a tree holds together the soil and stops soil erosion.
Soil erosion brings less fertile soil on the earth’s surface, if this process is not stopped well within time, the land may soon turn into a barren land or a desert. The crops will no longer grow in such an unfertile soil, and soon there will be food scarcity. Now who wants to go hungry to bed? We can prevent soil erosion by preserving the forests, and planting more trees.
How can we Conserve Soil?
When a piece of land is not being used for agriculture, it is a good idea to grow grass, plant, flowers and trees on it. Doing so, would keep the top soil firmly in place and prevent the soil erosion. Another good method is terrace farming. Farm lands on hill slopes are cut out into steps or terraces, so that when water runs down the slope, the top soil does not get washed away, and is absorbed in the same area.
Deforestation
The need to construct buildings, dams, shopping malls, extraction of ore, oil and natural gas has led to a reduction in forests. Deforestation refers to removing of trees from a forest area for the purpose of commercial use. It is a process that involves cutting down of trees and clearing a big forest patch for smaller bio-diverse ecosystems, such as, plantations,...

Planting trees in semi-arid areas attracts rainfall and prevents such areas from becoming deserts. Aforestation prevents soil erosion and conserves the fertile top soil for agricultural use.
Employment through Afforesttaion
Governments on the globe have devised several tree-planting programs that engage people to sow seed and plant saplings. Thus, it provides job opportunities for people. Even ecotourism, help people to earn their livelihood.
Activity 2: Give Your Opinion!
On an A4 size paper, write your opinion on any one topic given below.
• Write a letter on Plants – Forest as A Resource that informs people about its importance and how they can make their contribution.
• Write a letter to the local newspaper to educate them on the importance of recycling, reusing, and reducing the use of paper products to prevent deforestation and global warming.
Tropical rainforest have lots of rain because it is very hot and wet due to its location along the equator. That means that there is more direct solar radiation hitting the land and sea there than anywhere else. They release moisture into the atmosphere which returns to the ground as rain. It rains more than ninety days a year in tropical rainforests and the strong sun usually shines between the storms. The water cycle repeats often along the equator. The main plants in this biome are trees. Tropical rainforests store water like a huge sponge. In fact, it’s believed that the Amazonian forests alone store over half of earth’s rainwater a lot of the rain that falls on the rain forest never reaches the ground. It stays within the trees because the leaves act as a shield, and some rain never gets past the trees to the smaller plants and grounds below. Surprisingly, soil in rainforests is very poor in nutrients. This is because the nutrients are stored in the vast numbers of trees and plants rather than in the soil. Tree roots bind the soil together, while the canopy protects the soil from heavy rains. W...
Soil erosion began with the dawn of agriculture, when people abandoned their hunter-gatherer lifestyles and began using the land for intensive agriculture, thus removing the protective vegetation cover and growing food crops on disturbed soil surfaces. For many civilizations, it is believed that surface wash erosion, that can occur unnoticed until it is too late, was a main contributing factor for their demise. Soil erosion and other degradative processes have destroyed, over the millennia, as much arable land as is now cultivated.
Agriculture need to be evolved in such a way that that it becomes more sustainable and environment friendly. Effective techniques can be incorporated in such a way that high crop yield can be achieved from less area of land which will reduce deforestation. Reforestation practices should also be inculcated into the locals so that they can be a part of that process. This will increase the reach and involvement level of people in reforestation process.
In cases of a lack of vegetation soil is exposed to erosion. Wind erosion blows the top soil off especially in the sandier areas where there are finer particles. Animals or cultivation of the soil can also break down soil particles into sizes that are more susceptible to wind erosion. This can cause a build up of soils in other places. Water washing over the loose, exposed soil can also result in large volumes of soil being lost. Most Australian soils are very shallow and have most of the nutrients in the top few centimeters. Erosion that carries away these top few centimeters of soil is particularly damaging. The remaining soil is unproductive, often unable to be re–taken over by native vegetation and susceptible to further
Soil and rock are the main composition of the planet’s crust. Rock is often considered a consolidated material but soil is described as an unconsolidated remains and deposits of solid particle that have been formed by the breakdown of rocks. Soils can be grouped into two categories depending on the method of deposition. Residual soils have formed from the weathering of rocks and remain at the location of their origin. Residual soils can include particles having a wide range of sizes, shapes and compositions depending on amount and type of weathering and the minerals of parent rock. Transported soils are soils that have been relocated from their original place. Transportation may have resulted from the outcome of gravity, wind, water glaciers or human activities. Transported soil particles are often segregated according to size during the transportation process. The method of transportation and deposition has significant effect on the
Deforestation is a widely used term, but one with different meanings. Disturbance deforestation refers to all man made disturbances that alter a forest, these are the most common. This argumentative essay discusses the positive and negative aspects of deforestation. In the first part of the essay the pro arguments of deforestation will be discussed. For example, the issue of Global population and how forests are being used, land use and the ways forests contribute, wood use, forest growth, destruction and the reasons for cutting down the trees. The second half of the essay will cover the issues that are harmful to the environment because of deforestation. Many environmental issues take place everyday; a big question that arises, is if the global economy will ever finds middle on the issue of forest thinning. If deforestation was used only in the most crucial of times, the world might become a better place.
The forests around the world a supply a plethora of community amenities and commercial goods , nevertheless forested terrain progressively is becoming transformed to accommodate other uses, including cropland, pasture, mining, and urban areas, which can produce superior private financial returns. The wide array of benefits the forest provides that vanish directly tied to deforestation have resulted in several policies drafted with the sole intention to reduce the frequency of deforestation. This paper has two primary objectives. First, this paper will review and summarize both the preceding and current research on deforestation. Second, it will emphasize the significance of future research and development, as well as other solutions needed
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
It is evident that the problem of deforestation is a challenge to stop but despite this, it is more manageable. Preserving intactness of these forests has an association with minimization of drastic climatical changes and fluctuations as well as global warming. In addition, the ecosystem and host habitats remain intact and, as a result, there is no extinction of species or displacement of indigenous communities that live in these
Restate thesis: In reality forests are better left alone, forests provide the earth with a regulated climate, strong biodiversity, and good nutrient rich soil for plants to strive on.
The loss of protective vegetation through deforestation, overgrazing, ploughing, and fire makes soil vulnerable to being swept away by wind and water.
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.
home farm. Reducing soil erosion is one of the most important practices on my home farm.
Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it’s formed.
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.
