Preserve the Forests In agreement with Kim Stafford‚ who opposes the clear-cutting of old growth forests‚ I feel that it is necessary to preserve the profitable lumber in its natural state for future generations. Currently‚ the tons of lumber produced from the Pacific Northwest region of the United States are taken for granted‚ and most people do not realize that the forests will be destroyed within ten years at this rate of exploiting our natural resources. We must make loggers a profession

What is Soil? Soil is the surface of the earth’s crust where plants have their roots and where many small animals make their home. It is also a result of the breakdown of rocks. Formation of Soil Soil is formed when rocks break down into very small particles by various processes such as weathering. There are two types of weathering: Physical Weathering and Chemical Weathering. Physical Weathering arises from the heating and cooling‚ the wetting and drying‚ and the freezing and

SOIL EROSION Janeen Uy I BS MANAGEMENT ES 10 J Submitted to: Dr. Severino Salmo III March 8‚ 2012 Soil is found on the Earth’s crust and formed through weathering and decay of organisms. It may be considered dirt to a lot of people but it is highly an important tool for our survival. The soil holds the roots of the plants where nutrients are stored. It is important since it enables the soil to store and regulate the flow of water‚ filters the pollutants and improves the soil’s quality

The soil is an important part of the landscape and contributes to determine the way in which natural vegetation‚ crops and human settlements are distributed on the territory. But the importance of the soil is mainly related to its double role as a reserve of nutritional elements and water and mechanical support (how would plants be able to stand upright if they did not have the soil to put their roots in?) for vegetation‚ leading to the creation of forests and protected areas. A direct observation
Free Life Biodiversity Natural environment
Soil is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral

Kenneth R. Sagum May 7‚ 2013 FR1 NATSCI1 “Effects of Soil Erosion in the Philippines” The soil is among our most precious resources‚ yet we often take it for granted or destroy it by making it susceptible to soil erosion. In the Philippines‚ for example‚ 22 provinces had been reported to have "alarming" soil erosion rate. Among those that had been losing their topsoil were Cebu‚ Batangas‚ Marinduque‚ Ilocos Sur‚ and La Union. This means that 58 per cent of the country’s total

SOIL POLLUTION INTRODUCTION Soil is the thin layer of organic and inorganic materials that covers the Earth’s rocky surface. The organic portion‚ which is derived from the decayed remains of plants and animals‚ is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments‚ was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient
